12.1 Introduction

Micronization is a size reduction in which particles are reduced down to micrometer resulting in particle-size distribution is less than 10 microns. Acceleration of particles has been involved for particle-to-particle impact or impact against a solid surface. Micron technology is an emerging technology which has a great potential in nutraceuticals and functional foods. By increasing the surface area per unit mass, compared with larger-sized particles of the same chemistry, tiny particles are made more biologically active. A lot of attention has been gained by micronization in food research and development. Functional properties, surface areas and structures gets altered by reduction in particle sizes of different materials (e.g., metal salts, metal oxides, chitosan and organic compounds) by micronization or nanotechnology to micro- or nano-sizes and bring some new applications in the academic world as well as in food industry.

They absorb a large concentration (10-40 wt %) of C0₂ that either swells the polymer or melts it at a temperature below (10 to 50 °C) it’s melting/ glass transition temperature hence, this technique is useful for micronization of especially for polymers. Active substrate(s) in a polymer or other carrier substance can be used with suspensions for micronization process. In manufacturing advanced pharmaceuticals, coating materials, micro sensors, polymers and many other chemicals particle design has been gaining importance. Formulation homogeneity and control particle size can be improved by micronization. Moreover, bioavailability of poorly soluble APIs (active pharmaceutical ingredient) by increasing particle surface area and accelerating dissolution rates can also be improved. Because of the high impact velocities possible as a result of particle acceleration in a fast gas stream, fluid energy mills are used for micronization. Particle velocities in a jet mill are in the range of 300 to 500 meters per second, compared to 50 to 150 meters per second in a mechanical impact mill, in many industrial fields like food technology, pharmaceuticals, catalysts, pigments, and biopolymers, for example, are some categories of products that can be used as micro-sized particles, micronized powders are of great interest. High-temperature reactions that require high energies, on jet milling that is characterized by low efficiencies and mechanical stress, and on liquid solvents precipitation that has a poor control on particle size and can pollute the product comes under the traditional techniques for producing micronic powders. Generally, the control of the powder size and the span of its distribution are still very approximate. In recent years, many supercritical fluids-based techniques have been developed for the production of micronic and nanometric particles. Some particular properties of gases at supercritical conditions such as enhanced solubilization modulation and its power, large diffusivities, organic solvent reduced operation, and the connected possibility of controlling powder size and distribution resulted from this process. Important characteristics of powders like particle size and size distribution have significant effects on dissolution properties, flowability and release kinetics. Therefore, particle engineering is the most important step during processing of powdered foods. Lower micrometer range and sizes are needed for many applications particles with special requirements. Processes like jet milling, pearl milling or high pressure homogenization are used for micronization.

Pesticide Toxicity

Chemical tactics to manage pests can include many types of compounds. Some merely repel or confuse pests. Some interfere with weed photosynthesis, insect molting processes or development in some way. Others, including some botanical and most conventional insecticides are broadly toxic to living systems. The term pesticide literally means “pest killer". Generally speaking, when using pesticides, we are trying to garner the advantages of using pesticides while minimizing the risk to humans and other non-target organisms. Risk to humans of pesticide use is often described as:

ABSTRACT

Traditional herbal drug preparations are known for centuries to protect several human diseases such as peptic ulcer, diarrhea, piles and dysentery. Current days knowledge about the underlying biochemical mechanism for most of the gastric ulcers and majority of the duodenal ulcers deserve appropriate consideration and due weightage while consolidating regarding the efficacy of a plant extract. The present investgation relates to a pharmaceutical composition comprising an effective amount of lyophilized extract or at least one bioactive fraction obtained from flowers of Woodfordia fruticosa (L.) Kurz, along with one or more pharmaceutically acceptable additives or carriers. The present results provides a composition for treating ulcers such as stress induced ulcer, peptic ulcer, cold restraint induced ulcer, drug induced ulcer and acid induced ulcer, and also the composition used as specific inhibitor of gastric H+, K+-ATPase. Herbal formulation in the form of capsules were conducted on marker-based stability studies as per ICH Q1 guidelines at accelerated and real time stability studies (40±2°C, 75% ± 5% RH and 30±2°C, 65%±5% RH, respectively), and also stability testing investigation was done as per stability specifications at intervals of 0, 3, 6 months for accelerated stability studies and 0, 3, 6, 9, 12, 18, 24, 36 months for real time stability. The present data reveals that this species is one of the potent Indian medicinal Plant which helps in curing ulcer and associated diseases.

Abstract: Genus Jasminum contains 90 species to be true in existence and use, range from landscape to hair adornments, and perfumes. It is native to Indo-Malayan region. Morphological variants from different species have been developed in different regions in India. Unfruitfulness, cross incompatibility, pollen and seed sterility, delicate flower parts, peak and active night flowering, endosperm antagonism often pose significant challenge to breeders. Genetic information and trait heritability is almost unknown for this crop. Phenotypic traits requiring future improvement include recurrent flowering for fresh flower market, high concrete recovery, biotic and abiotic stress tolerance. Future breeding and genetic studies are needed for further transform this crop.

ABSTRACT

Donor-recipient protoplast fusion vis-à-vis cybridization is an effective technique to transfer plasmon-coded traits in cultivated tetraploid (2n=4x=48) potato (Solanum tuberosum L.) from its diploid (2n=2x=24) cross-incompatible wild relatives. However, the method, although attractive, is difficult in terms of not only inactivation of nuclear and plasmonic genomes of the participating donor and recipient protoplasts, but also post- fusion culture and regeneration of putative cybrids. Here, we report an improved method for donor-recipient protoplast fusion and subsequent post-fusion culture and regeneration of electrofused protoplasts in potato. In the present experiment, Solanum verrucosum Schlechtd. (2n=2x=24) accessions CPC 1339 (CGN No. 17774) and HAW 2246 (CGN No. 17766) containing sensitive [Tr^s] plasmon for tetrad-type cytoplasmic male sterility were used as donors and S. tuberosum subsp. tuberosum cvs Kufri Ashoka, Kufri Chipsona-1 and Professor Broekema as recipients. For nuclear inactivation, the in vitro-cultured donor plants were exposed to 1000 Gy of unfiltered γ-rays before protoplast preparation using a revised protoplast isolation medium (PIM) containing 2.0 % Cellulase ‘Onozuka’ RS and 0.25 % Macerozyme R-10. The recipient protoplasts were treated with antimetabolite iodoacetate (1.0 mM ) for 45 min at 10 °C for chondriome inactivation. The protoplasts were aligned in an amplitude of 300 Vcm^-1 for 0.5-1.0 s before being electrofused by one DC pulse of 600-800 Vcm^-1 for 40 μs using a Cell Electrofusion Processor FPH 01001 (Bioelectronics Corporation, Troy, Michigan). The fused protoplasts were immobilized in alginate-plates, and cultured on modified VKM medium containing 0.3 M glucose at about 400 mOsmol (pH 5.6). After 8-10 weeks, the developing protocalluses were dissociated from alginate-plates and cultured for regeneration on MS medium supplemented with varying concentrations of zeatin/ zeatin riboside and gibberellic acid. The protocalluses derived from electrofusion between donor S. verrucosum accession CPC 1339 and recipient S. tuberosum cv. Kufri Chipsona-1 could be successfully regenerated into plantlets. Morphological as well as molecular-genetic characterization of regenerated microplants, both for nuclear and chondriome genomes, confirmed the putative cybridity as well as established the extent and pattern of mitochondrial recombination following donor-recipient protoplast fusion. The results have been discussed in relation to donor-recipient protoplast fusion approach and its potential application in potato genetic improvement.

Introduction

Spatial data is different from a non-spatial data in the sense that it always has a spatial reference system which is nothing but a pair of coordinate values and a system of reference for these coordinates. For example, the locations of benchmark soil series of India can be defined as pairs of longitude and latitude in decimal degree values with respect to the prime meridian at Greenwich and zero latitude at the equator. The World Geodetic System (WGS84) is a frequently used system of reference on the Earth. The different types of spatial data are: (i) point, which is a single point location, such as a GPS reading or a geocoded address (ii) line, which is defined as a set of ordered points, connected by straight line segments (iii) polygon, an area, marked by one or more enclosing lines, possibly containing holes and (iv) grid, a collection of points or rectangular cells, organised in a regular lattice. Among the above said spatial data, the first three are vector data models and represent entities as exactly as possible, while the fourth data model is a raster data model, representing continuous surfaces by using a regular tessellation. In this chapter, we discuss how a spatial data can be handled in R. There are several packages available in R in which spatial data analysis can be handled e.g. sp, rgdal, raster etc. All the contributed packages for spatial data analysis in R address two broad areas: moving spatial data into and out of R, and analysing spatial data in R. In the following section, the sp package for spatial data handling is briefly discussed.

An area with similar soil, climatic conditions and resource availability resulting in similar type of crops and cropping systems. Ex. Rice based cropping system, Ragi based cropping system, Wheat based cropping system, Cotton based cropping system etc.

Efficient cropping zone: An analysis of productivity efficiency of crop was made by Kanwar (1972) using relative yield index (RYI) and relative spread index (RSI).

A zone where both yield and spread indices are maximum that is above 90 per cent is called most efficient and in case of indices below 90 is the least efficient zone of a crop.

Dry Root Rot / Charcoal Rot

Macrophomina phaseolina

Economic Importance

• Dry root rot has been found in most of the soybean-growing areas of the India.
• The disease has been increasing in importance and can result in substantial yield losses.
• In most fields, stand losses range from less than 5% to over 50% in severe cases.
• It is most prevalent on seedling and young plants, causing a root and stem rot.

ABSTRACT

Colchicine, one of the most widely used alkaloids is synthesized in Gloriosa species, a plant of great medicinal importance. The seeds, tubers and leaves of six different species of Gloriosa were phytochemically investigated for alkaloids and were found to contain colchicine and colchicoside. These alkaloids were isolated and quantified by HPLC analysis. This is the first report of alkaloids in Gloriosa plantii, Gloriosa lutea, and Gloriosa vuchuria. The colchicine and colchicoside content of the Gloriosa species was found to be organ dependent as there was statistically significant differences (P<0.05) between different organs but not among different species under study. The total alkaloids are organ as well as species dependent as there were statistically significant differences (P<0.05) between all the species as well as organs of different species of Gloriosa under study and its organs.

Abstract

Jasrota Wildlife Sanctuary (JWS) in Jammu and Kashmir (J&K) Union Territory is floristically less explored. Between 2018 and 2019, field surveys and exploration tours were undertaken to obtain information from local people residing around JWS through open interviews, semi-structured questionnaires and group discussion. Total 113 informants were contacted and data collected by means of ‘snowball method’. A total of 138 species of 60 medicinal plant families were documented subjected to preliminary investigation, which includes 47.10% herbs, 28.26% trees, 19.57% shrubs, 4.35% lianas, and 0.72% parasites. Most dominant families were Fabaceae (11 gen. and 12 spp.), Lamiaceae (6 gen. and 8 spp.), Asteraceae (8 gen. and 8 spp.), Moraceae (2 gen. and 6 spp.), Caesalpinaceae (4 gen. and 6 spp.), Rosaceae (5 gen. and 5 spp.), Euphorbiaceae (4 gen. and 5 spp.), Solanaceae (4 gen. and 4 spp.) and Malvaceae (4 gen. and 4 spp.). Some of the common high valued medicinal plants were Ajuga integrifolia, Aloe barbadensis, Asparagus adscendens, Boerhavia diffusa, Cassia fistula, Lantana camara, Murraya koenigii, Ocimum tenuiflorum, Tinospora cordifolia, Zingiber officinale and several other plants. Traditionally lesser used plants were Abrus precatorius, Acacia catechu, Commelinabenghalensis Cyperus rotundus, Silene vulgaris, Robinia pseudoacacia, Urtica dioica and Ziziphus mauritiana. These medicinal plants are used in treatment of obesity, anti-helminthic, liver infection, diabetes, intestinal infections, rheumatism, tumours, stomachache, insomnia, nerve troubles, skin infection, aphrodisiac, memory related disorders, dermatological problems and asthma. Species with high frequency index should be analyzed for pharmacological research and for discovering of new medicines. It has been observed that lots of medicinal plants grows in this protected area and this sanctuary need proper conservation and management planning.

Alimentary canal : The endoderm is formed by delamination in mammals and birds. This endoderm surrounded by splanchnic mesoderm forms the gut. The endoderm underlying the embryonic disc and serving as a flat roof to the early yolk sac becomes gut endoderm. At 20^th day a rapidly expanding embryonic disc begins to fold into a cylindrical embryo. The gut endoderm also participates as a component layer. Folding first into the head end and then into the hind end of elongating embryo this endoderm necessarily takes the form of the two internal blind tubes. The open end of the each tube where it becomes continuous with the yolk sac is called an intestinal portal while the tubes are named the foregut and hindgut. The caudal end of the hindgut is cloaca. An intermediate region opening ventrally into the yolk sac through the narrower yolk stalk is midgut.

Mole

A mole is defined as the amount of chemical substance containing exactly 6.022 140 76 × 10₂₃ numbers of constitutive particles such as atoms, ions and molecules. This number is a fundamental constant named Avogadro’s number in honor of Italian scientist Amedeo Avogadro. This constant is properly reported with an explicit unit of “per mole,” and rounded version being 6.022 × 10₂₃/mol.

This definition has been adopted since November, 2018 revising the old definition based on the number of atoms in a sample of pure ₁₂C weighing exactly 12 g. Thus, as per the definition, 1 mole of any element contains the same number of atoms as 1 mole of any other element. However, the mass of 1 mole of a particular element is different from that of another element.

Molar mass

Molar mass of an element (or compound) is the mass in grams of 1 mole of that substance, a property expressed in units of grams per mole (g/mol).

Rice

Plant parasitic nematodes cause serious damage to rice crop. Thirty two species belonging to 13 genera were observed in association with the crop. Among them few are considered to be important. They are the rice white - tip nematode (Aphelenchoides besseyi), rice stem nematode (Ditylenchus angustus), rice root nematode (Hirschmanniella oryzae), root-knot nematode (Meloidogyne graminicola) and the cyst nematode (Heterodera oryzicola).

The white-tip nematode (Aphelenchoides besseyi)

The yield loss due to the white-tip nematode is estimated to be as much as 17.4 to 54.1 per cent. The nematode is distributed in India, Bangladesh, Sri Lanka, Japan, Indonesia, Taiwan, Former USSR, Italy, Cuba and Madagascar.

3.1 INTRODUCTION

A nursery is a place, where seedlings, saplings, trees, shrubs and other plant materials are grown under intensive care and maintained until they are ready for final transplanting in the main field. The importance of the best quality planting material as an initial investment is a well-realized factor for persons engaged in horticulture field. So, nurseries have great demand for the production of plants, bulbs, rhizomes, suckers and grafts. But in general, good quality and assured planting material at reasonable price is not available in most of the cases. Nursery is the basic need of horticulture. Plant propagation techniques and practices is the core of horticulture nurseries. The planting materials for horticultural plantations are raised from seeds and vegetative parts. The difficulty of procuring seeds and their rising cost makes it necessary to find means to increase seedling survival and growth.

5. Description

Indian Butter tree (mahua) is one of the most important trees of Indian forest. It produces delicious and nutritive flowers, fruits, seeds and valuable timber. It is a deciduous tree with a large, spreading, rounded crown that can grow 16 metres or more tall. The short main trunk can be up to 80 cm in diameter. Mahua is an indigenous tree of high economic value. A characteristic tree of the dry region, it is found in north and central India. The tree is very well known to rural folk since ages in India. Its flowers, fruits, and oil obtained from seeds are eaten in various ways. Mahua flowers are a rich source of sugar containing appreciable amount of vitamins and minerals. Fruit is eaten as raw or cooked. Pulp is a good source of sugar, whereas dry husk makes a good source of absolute alcohol. Seed is a good source of oil.

Planting System

Main objective of layout is maximum number of plant accommodated in per unit area without affecting the efficiency of production. If more than one fruit is included in the orchard plan, each kind should be grouped into individual block. Similarly fruit ripened in particular season should be grouped to facilitate convenience in watch and ward, harvest and post harvest handling. Some kind of fruit trees need pollinators/pollinisers for improving the fruit set.

Abstract

Now-a-days non bovine milk become an area of interest for their potential to provide nutrients along with beneficial health effects. Deer belongs to cervidae family, is one of the source of non bovine milk. Two thousand years ago, the people of Soviet Union along the borders of Russia, Mongolia, and China used to consume deer milk and milk product. Deer milk is a plentiful source of milk solids. The proteins of deer milk is more digestible than bovine milk owing to their unique profile and characteristics. Deer milk being rich in highly digestible protein offers beneficial health effect through bioactive peptide production. The distinctive physico-chemical properties being quite similar to sheep milk shows the milk product manufacturers a scope to use deer milk for production of various dairy products. Although there is immense opportunity to use deer milk for development of diversified functional products, further research work is needed to be carry out to find out the type of biopeptides produced during protein hydrolysis, role of fatty acids, effect of different unit processing on its constituents etc. This chapter delineates the nutritional profile and physico-chemical properties of deer milk along with the significance of it in terms of its therapeutic roles and potential to be used for product development.

Coffee is a much sought after beverage and plantation crop grown in about 80 countries across the globe of which over 50 are considered to be major producers. Coffee is also the second largest traded commodity in the world, next to petroleum products and is popularly referred to as “Brown Gold”. Coffee contributes substantially to the national exchequers of the producing countries through export earnings and also generates employment to about 120 million people in production, processing and trading, worldwide. The economic relevance of coffee is underlined by the fact that it generates significant income throughout the supply chain, representing a gross added value of over USD 458 billion annual (Belo Horizonte Declaration, International Coffee Organization, Sept. 2013). The annual revenue of the coffee industry alone is estimated to exceed USD 200 billion. At origin, production of coffee provides livelihood for up to 25 million farmers and their families. (Coffee Development report, ICO, 2019).

Caffeine is a major pharmacologically active compound in coffee and it is a mild central nervous system stimulant. ³. In addition caffeine is added to many popular carbonated drinks and is also a component of a number of pharmacological preparations and over-the-counter medicines. A typical cup of coffee provides approximately 75–100 mg caffeine. The European Food Safety Authority (EFSA) in its ‘Scientific Opinion on the Safety of Caffeine’ concluded that ‘habitual intakes of caffeine up to 400 mg per day do not give rise to safety concerns for non-pregnant adults. They also advised that intakes up to 200 mg per day do not give concern for those who are pregnant or breastfeeding.
