Starch is the storage form of carbohydrates in plants which is abundantly found in roots, tubers, stems, fruits, and cereals. It is a polysaccharide made up of glucose monomers with a chemical formula of (C6H10O5)n. Starch is composed ofamylose and amylopectin. The linear polymer amylose is the most basic form of starch while amylopectin is the branched form. Foods that are high in starch content are a good source of nutrition. Food starches are used in the food industry as thickeners and stabilizers. During the ripening of fruits, the starch is converted into sugars. Therefore, the presence of starch in fruits is used as an indication of maturity and ripening.
Principle: For estimation of starch contents, the sugars present in the sample are leached out and starch is hydrolyzed using either acid or enzymatic hydrolysis. Stach is then calculated as invert sugars.
Starch content by Acid Hydrolysis method
Reagents: Ethanol 95%, /50%,Concentrated HCl, Concentrated H2SO4, 1N NaOH solution, Phenolphthalein indicator, 10% alcoholic solution of Alphanaphthol.

Introduction

India is the largest banana producer in the world. They grow bananas on an area of 9 million hectares and get 36 MT per hectare. India exported 2,000,000 MT of banana worth $1 billion to other nations. The banana production system supports the labour market, alternative food system, export eco-system, and nutritional security, among other things. The development of climate-resilient banana varieties, tissue culture protocols, macro-propagation, ornamental bananas, micronutrient mixtures, site-specific nutrient management, biocontrol agents for pest and disease control, robust virus diagnostic kits, and so on are all highly recommended and encouraged to make the banana industry sustainable and profitable in the long run. Technologies and products for use after harvest are also vital. Branding, supporting entrepreneurship via incubation platforms, marketing intelligence, and handholding for technical support are necessary to sustain banana production and drive value addition. Bananas and plantains, more than any other fruit or vegetable, constitute a staple food for millions of people worldwide and contribute to a healthy diet. In addition to carbohydrates, it's a wonderful source of potassium, vitamins, and minerals. The fat-free fruit has a calorie count of 90 per 100 grams. Dessert bananas are normally eaten raw, while plantains or cooking bananas are commonly prepared in a variety of savoury ways, such as boiling, steaming, frying, or roasting. The banana industry has expanded in recent years, making a greater contribution to the economy in terms of both employment and food supply.

Livestock farming is an important activity to a large population of small and marginal farmers as well as landless agricultural labourers of Tamil Nadu. It also provides employment opportunities for most of the unemployed and underemployed in the rural areas. Tamil Nadu is bounded by the Eastern Ghats on the north, by the Nilgiris, the Anamalai Hills and Kerala on the west, by the Bay of Bengal in the east, and by the Indian Ocean on the south. Tamil Nadu is the eleventh largest state in India by area. The land area has been classified into seven agro-climatic zones based on soil characteristics, rainfall distribution, irrigation pattern, cropping pattern and other ecological and social characteristics. Tamil Nadu endowed with 13.97 per cent of recognised breeds of the domestic ruminants (cattle, buffalo, sheep and goats) with 22.55 millions of population (19^thLivestock Census-2012).

“It is unbelievable that such a tiny streamlet, as was our initial test trial with the first bacterial starters exactly 40 years ago, grew to a big river for an important industry. Who would have believed then that the use of starter cultures would be a matter of course today” (Niinivaara, 1994). The idea of inoculating Lactobacillus into dry sausage material was introduced by Jensen and Paddock in 1940(US Patent 2,225,783) with the aim to reduce the ripening time as well as ensuring the quality and aroma of dry sausages. The first LAB meat starter culture, introduced as a pure culture of Pediococcus cerevisiae, was developed in 1955 in the USA by Niven et al. (1955). At the same time, Niinivaara (1955) applied Micrococcus M53 to dry sausage production in Europe. The work of Niinivaara was continued byNurmi (1966) who combined micrococci with Lactobacillus plantarum. Today, several companies provide Lactobacillus sp., Pediococcus acidilactici, P. pentosaceus, Staphylococcus xylosus or S. carnosus strains in pure cultures or their mixtures for fermentation of meat (Hammes et al. 1985). A starter culture may be defined as a preparation or material containing large numbers of variable microorganisms, which may be added to accelerate a fermentation process. Being adapted to the substrate, a typical starter facilitates improved control of a fermentation process and predictability of its products (Holzapfel, 1997).

Starters are selected strains of micro-organisms deliberately added to milk during conversion into cheese, dahi, yoghurt and other fermented dairy products to bring about specific changes in the appearance, body, texture and flavour characteristics of the desired final products.

Functions of Starters

The primary function of almost all starter culture is to develop acid in the product. The secondary effects of acid production include coagulation, expulsion of moisture, texture formation and initiation of flavour production. In addition to these, the starters also help in imparting pleasant acid taste, conferring protection against potential pathogens and providing a longer shelf life to the product. These bacteria convert 1% of lactose in milk approximately to lactic acid with very little by-products such as acetic acid, ethanol, CO2 and normally with no substances causing taints and hence leading to a clean and wholesome milk souring.

Starter cultures were unknown until 1878, when Lister isolated pure cultures of the lactic acid bacteria responsible for milk acidification. In the 1980s, improvements to standardization and ripening of butter were made by introducing pure starter cultures. During the period 1910-20, Orla-Jensen, von Freudenreich, Sherman, Hammer and other dairy microbiologists prepared pure cultures for fermented milks. Commercial production and use of starter cultures grew rapidly and was widespread at the beginning of the 20^th century.

Dairy starters are the ‘heart’ of fermented milk products, the most crucial component in the manufacture of high-quality fermented milks. The cultures are harmless food-grade microorganisms, active bacteria intentionally grown in milk or whey or other formulated media which impart desirable and predictable flavour and texture to fermented dairy products.

The dairy microorganisms employed in milk fermentation are single-strain or multiple-strain cultures of lactic acid bacteria, producing different types of fermented milk products. Usually, one or two strains dominate the milk environment. Individual strains can be selected in advance for their resistance to both bacteriophages and antibiotics. Mixed starter cultures are used to ensure that fermentation will continue after a bacteriophage attack. Bacteriophages are highly strain-specific, and if the dominant strain in a mixed-strain starter culture succumbs to an attack, the phage-resistant mutant or the next dominant culture maintains a satisfactory rate of lactic acid production.

Startup India, the initiative of Government of India, was first announced by Honourable Prime Minister Mr Narendra Modi during his Independence Day speech on 15 August, 2015 and discussed elaborately again on 27 December 2015 in his radio address ‘Maan ki baat’ mentioning startup as new opportunities for the youth who want to set up new business or innovative projects. Indian Government lunched this ‘Startup India – Standup India’ campaign on 16 January 2016 with an intention to build a strong startup ecosystem for nurturing innovation and encouraging private investment.

Chapter 6 delves into the critical role of monsoon rainfall in shaping the economies and lives of numerous countries across the globe. While the concept of a country being only dependent on monsoons is a simplification, this chapter focuses on regions where the seasonal monsoon rains are the paramount source of freshwater for agriculture, industry, and daily life. These monsoon-dependent nations, predominantly located in South Asia, Southeast Asia, Australia, parts of Africa, and even areas of South America, experience a dramatic annual cycle of wet and dry periods dictated by the shifting monsoon winds. The arrival and intensity of the monsoon rains are not merely meteorological events; they are pivotal determinants of agricultural yields, food security, economic stability, and the overall well-being of billions of people. Given this profound dependence, accurate and timely forecasting of monsoon rainfall is of paramount importance. The second part of this chapter explores the current state of the art in monsoon forecasting. We will examine the sophisticated methodologies and technologies employed by meteorological agencies and research institutions worldwide to predict the onset, duration, intensity, and spatial distribution of monsoon rains. This includes an overview of empirical models leveraging historical climate data, the increasing reliance on complex dynamical models that simulate atmospheric and oceanic processes, and the integration of advanced statistical techniques like Bayesian methods and downscaling to enhance forecast accuracy and regional specificity. Understanding the strengths and limitations of these cutting-edge forecasting techniques is crucial for effective water resource management, agricultural planning, disaster preparedness, and ultimately, for building resilience in monsoon-dependent regions.

West Bengal

In West Bengal, mangroves are present in Sundarbans, the large deltaic complex of three major rivers, the Ganges, Brahmaputra and Meghna, and 62% of total area is shared by Bangladesh and 38% by India. The Sundarban Biosphere Reserve (SBR), at the confluence of the Bay of Bengal covering an area of 9,630 km², lies between 21°40′N and 22°40′N latitudes and 88°03′E and 89°07′E longitudes, spreading in districts of South and North 24-Parganas in West Bengal, India. The major portion of SBR is designated as Reserve Forest, covering nearly 4260 km² and the area under mangrove vegetation is 2112 km² (FSI 2019). Compared to 2017 assessment there has been a decrease of 2 km² area of mangroves. The mangroves and their associates in the SBR exhibit great generic and species diversity and it is abode to rare and highly endangered flora and fauna, as well as, the only mangrove-tiger (Royal Bengal Tiger - Panthera Tigris tigris) kingdom in the world. Recognizing importance and uniqueness, the United Nations Educational, Scientific and Cultural Organization (UNESCO) declared the Indian part of Sundarbans as a ‘World Heritage Site’ in 1987, and also designated the ‘Sundarban Biosphere Reserve’ under the UNESCO Man and the Biosphere (MAB) program in 2001. Recently, Sundarbans has been declared as a Ramasar Site, considering ecological significance. Totally 33 true mangrove species belonging to 21 genera and 13 families have been identified in Indian Sundarbans. Among the mangrove species listed, Rhizophora apiculata, Bruguiera parviflora, Ceriops decandra, Kandelia candel, Aglaia cucullata, Excoecaria indica, Xylocarpus moluccensis, Xylocarpus granatum, Heritiera fomes, Scyphiphora hydrophyllacea, Brownlowia tersa, Nypa fruticans, Acanthus volubilis, Dolichandrone spathacea and Phoenix paludosa are under serious threat in Sundarbans (Kathiresan 2008; Gopal and Chauhan 2006). Particularly Heritiera fomes (locally called Sundari, from which Sundarbans derives its name), Nypa fruticans and Phoenix paludosa are declining rapidly due to the reduction of freshwater input (Gopal and Chauhan 2006).

Abstract: Limoniums, popularly called as statice/ Sea lavender are morphologically diverse and admired for their ornamental value. Perennial annual statice is widely cultivated worldwide for both, garden decoration and indoor decoration. This chapter includes a short overview of the taxonomic and reproductive behaviour of the genus. Majority of the species are triploids and reproduce apomictically. Limoniums exhibit incompatibility linked with pollen and stigma dimorphism, heterostyly and biparental inbreeding and species cross compatibility leading to genetic variability. Many F₁ hybrids are available for commercialization as potted lines. Use of tissue culture, molecular markers, embryo rescue, cryopreservation, super compact transgenic clones has been discussed. No genetic information and trait heritability has been established for this crop. Traits of interest to flower breeders for crop transformation include: plant architecture, panicle length, number of branches per panicle, novel colours of both calyx and corolla, high number of flowers per stem, environmental adaptation to stressful conditions, etc.

Keywords: F₁ cultivars, interspecific hybridization, polyploidization, self incompatibility, potted plants.

Statice, botanically known as Limoniumis very highly demanded ornamental plant. It is also known as ‘Sea Lavender’ owing to its color and place of growth. The genus name Limonium is from Greek name ‘leimon’ which translates to origin ‘a meadow’, most suitable as many species are found growing near marshy lands or salty areas of sea shore. The statice plants have very wide adaptability and can be seen growing under a wide range soil and climatic conditions like sea shores, marshy lands, deserts and plains etc. Statice figures in top 20 cut flowers sold worldwide but information on its trade, volume, export-import and number of stems sold etc. is not available. The reason for this may be attributed to classification systems, data collection categories and frequently changing nature of the assortments in the international flower market. Comprehensive trade statistics are difficult to locate for Statice. However, Statice figured in top 10 imported products in the Netherlands way back during 2013, 2014 and 2015. Though it is presently not among the top 10 flowers category, still it enjoys the immense popularity among the growers owing to its ease in cultivation and other characteristics. It is cultivated as annual as well as perennial crop, as different species have been domesticated for this purpose.

Statistics as a wide subject is used in almost all disciplines especially in research studies. Statistics provides scientific tools for representative data collection, appropriate data analysis and summarization of data and inferential procedure for drawing valid conclusion in the face of uncertainty. Each and every researcher should have some knowledge in Statistics and must use statistical tools in his or her research, one should know about the importance of statistical tools and how to use them in their research or survey. The quality assurance of the work must be dealt with: the statistical operations necessary to control and verify the analytical procedures as well as the resulting data making mistakes in analytical work is unavoidable. The emergence of statistical software in the twenty-first century has helped different researchers in the physical and social science to improve in the quality of research. Most renowned researchers in adopting this software in their data analysis have been able to identify the immense contribution to research findings (Adetola, 2013). Any quantitative research cannot be done effectively without Statistical Software. Moreover, it enables research data for easy presentation. It helps professionals to interact with data thereby paving way for creativity and innovation. Some are user friendly interface with drop-down tips for beginners (ATS, Ucla Edu, 2014). Advances in technology have improved all our lives (Akindutire, 2013) and has allowed experts greater freedom to come out with results within a twinkle of an eye than ever before where it takes time to finish analysis. This same technology has offer tremendous opportunity to research and keep research as a more interesting field of study. This study is significant, because it is an attempt to measure the direct impact of different statistical software on research analysis.

People all around the world have been conducting genetic association studies for a long time. Still the literature to practically understand the statistical analysis of such data using software packages is scarce. Statistical analysis of molecular data is a vast topic. So we will be undertaking one of the important basic and preliminary topics “Statistical analysis of genetic association studies among unrelated individuals” in this chapter. Overall, we will be discussing population association studies in which qualitative and quantitative data on unrelated individuals for various economic traits is collected and these individuals are also typed at a number of Single Nucleotide Polymorphism (SNP) markers. This excludes family-based association studies, admixture mapping or linkage studies. Various software packages used in this chapter to analyze molecular data of a population are given below in Table 1.
