Carnation (Dianthus caryophyllus L.) is one amongst the commercially important cut flowers traded worldwide. The genus Dianthus has about 300 species of annual, biennial and perennial herbs of which Dianthus caryophyllus is the most important species commercially. The genus Dianthus in Greek means ‘Flower of Zeus’ or ‘Divine Flower’. Linnaeus chose the species name, caryophyllus, after the genus of Clove, as the fragrance from carnation is reminiscent of clove. It is genetically a quantitative long day plant based on its photoperiod requirement (Blake, 1955). The Dianthus species are adapted to the cooler Alpine regions of Europe and Asia and are also found in Mediterranean coastal regions. Carnations were the first flowers to be cultivated on commercial scale in high altitude areas of tropics for export to Europe and North America.

It is cultivated throughout the world. The largest growing areas of carnation are in Bogota and Colombia. Carnation is also grown in Italy, Spain, Kenya, Sri Lanka, Canary Islands, France, Holland, Germany, Israel and USA. In India, main production areas are located around Pune and Bangalore. It is also being grown in Solan, Shimla, Mandi, Kullu, Chamba, Sirmour, Bilaspur and Hamirpur districts of Himachal Pradesh. As per the State Department of Horticulture - Himachal Pradesh, carnation occupied 44.07 hectares out of 705.77 hectare total area under floriculture in the state during 2018-19. The acreage of carnation is still expected to increase because of the favourable climatic conditions for its cultivation in different parts of Himachal Pradesh and other hilly states of the country.

In India, depending upon the regions, there is a wide difference in temperature, light intensity and humidity which not only affect the yield and quality of the flowers but also limit their availability for a particular period of the year. To produce quality flowers, carnation needs to be grown under cover, that is, in greenhouse which provides the plants with the optimum condition of light, temperature, humidity and carbon dioxide for proper growth and to achieve maximum yield of best quality flowers. Though, there are different types of the greenhouses, naturally ventilated polyhouses are preferred in mild climate in which temperature is reduced by ventilation (Ryagi et al., 2007).

INTRODUCTION

Carnation is one of the most beautiful and commercially important flower crop. It occupies prime position in the international cut flower trade and is a good commercial cut flower for internal market as well. Carnation flower can easily withstand long distance transportation as it has an excellent kee in ualit Its cut flowers with a 70 to 90 cm stem length, healthy and bright flower commands a better price. Carnations have a sweet fragrance and also commercially utilized for extraction of oil in France and the Netherlands. The volatile oil of carnation contain 40% benzyl benzoate, 30% eugenol, 7% phenylethyl alcohol, 5% benzyl salicylate and 1% methyl salicylate. It is used only in sophisticated perfumes. Carnation flowers round the year and have wider colour range like red, salmon, pink, purple, yellow, orange, bicolour, stripped, white and fancy combinations. The major break through in carnation flower industry was evolvement of cultivar William Sim. This cultivar was produced in 1938 to 1939 by William Sim of the USA. From this red variety there have been mutations to white, pink, orange and different variegated forms. The first genetically modified carnation variety Moon Dust is released in Australia by a plant biotechnology company Florigene. There are several distinct types of carnations and each of these can be grown in cooler parts of the plains and at medium to higher elevation. Carnations are cultivated under glasshouses in temperate countries and in the open or in semi-protected conditions under polythene cover, in both tropical and sub-tropical regions. Because of strong emphasis on quality in both export and domestic market, commercial production of spray and standard carnations is considered as a crop of protected conditions. Before being planted in the greenhouse, the crop must be carefully planted so that it will meet the demands of the international markets.

This chapter introduces carnation as an important commercial cut flower requiring controlled environmental conditions for producing long, straight and high-quality stems. It discusses varieties, propagation, planting, irrigation, nutrition and cultural practices such as pinching, disbudding, deshooting and plant support. The chapter also addresses plant growth regulators, pest and disease management, harvesting, grading, storage and postharvest handling. Emphasis is placed on protected cultivation practices that improve flower quality, yield and market value.

Carnation is one of the important cut flower crops grown throughout the world and occupies prime position because of the attractive colour, shape and good vase life. Due to the excellent keeping quality, wide range of forms, ability to withstand long distant transportation and remarkable ability to rehydrate after continuous shipping, carnation is preferred by growers to roses and chrysanthemums in several flower exporting countries.

Although cut carnations are sold in western countries all the year round, they are in particular demand for the Valentines Day, Easter, Mothers Day and Christmas. While standard carnations are in great demand, the miniature types are fast gaining popularity for their potential role in floral arrangement and also as cut flower at comparatively low price. White and pink standard carnations are in the greatest demand followed by red, yellow and bicolour. The liking for a colour depends upon the time or season. The re standard types are preferred to other colours, especially during the Christmas. In contrast in miniatures, the terminal flower bud is pinched to encourage clusters of short-stemmed small flowers. These types are mainly used for flower arrangement. (Bhatt, 1989)

Aphids: Myzus persicae : Aleyrodidae

Aphids are considered as the most serious pest of carnation. Both adults and nymphs suck sap from the leaves and debilitate the plants. They transmit carnation ring spot and carnation mosaic virus disease. They are thus more important as vectors. Regular monitoring for the incidence of the aphid and spot spray-ings of contact insecticides on the shoot tips can easily manage the pest.

Introduction

Carnation is one of the most beautiful and commercially important flower crops. It occupies prime position in the international cut flower trade and is a good commercial cut flower for internal market as well. Carnation flower can easily withstand long distance transportation as it has an excellent keeping.

The major breakthrough in carnation flower industry was evolvement of cultivar William Sim. This cultivar was produced in 1938 to 1939 by William Sim of the USA. From this red variety there have been mutations to white, pink, orange and different variegated forms.

The first genetically modified carnation variety Moondust was released in Australia by Florigene Company. They release another transgenic variety, i.e., Moonshadow.

In India carnation is grown intensively in Nasik, Pune, Srinagar, Bangaluru, Coimbatore, Delhi and Kolkata. Places having congenial climate like Kalimpong, Simla, Solan, Kullu, Ooty, Nainital, Chaubattia, Yercaud, Kodaikanal, etc. are most suitable areas for the production of cut flowers. From Himachal Pradesh and Ooty, rooted cuttings are supplied by the growers to the different parts of the country.

Abstract: Carnation, is one of the commercial flower crops of the world. There are many forms of carnations, which are excellent for cut flowers, bedding pots, edging and rock gardens. The history of crop improvement and development is highlighted. Their continued popularity has warranted extensive breeding and development of novel phenotypes particularly standards (Sims), sprays, midis, annual, picotees, perpetual, chabaud, malmaison, multiflora, microcarnations, etc. Continuous breeding and improvement of carnation focus on floral fragrance, floral doubleness, dwarf stature, high growth rate, floral colour, reduced calyx splitting, floral longevity and disease resistance. Ample genetic information and trait heritability has been established for this crop. Molecular genetics techniques are valuable tools aiding modern carnation breeders. Numerous genes have been identified and being used to create transformants. Wonderful results achieved through interspecific hybridization, mutation and polyploid breeding are discussed. Poor pollen production, inbreeding depression, linkage between traits, limited gene pool, inadequate seed production, reproductive barriers often pose significant challenges to breeders. Crop ideotypes prescribe numerous traits for incorporation by flower breeders and geneticists, including straight stem, symmetrical flower shape/ form, early/ uniform flowering with high productivity, enhanced shelf life and resistance to physiological disorders and various diseases.

Study of Carpentry Hand Tool

Introduction

The process of making the wooden components is called carpentry. Carpentry deals with the mechanical work of making wood components such as making beds, roofs, wardrobes, tables, cases, utensils, floors, etc. It manages the structure work, furniture, cabinet making and so on joinery, i.e., preparation of joints is one of the significant activities in all wood works.

The products produced are used in making furniture, musical instruments, and building constructions like doors, windows, desks, chairs, cupboards, etc., of a place utilizing a specific kind of wood with the help of tools known as carpentry tools. Different wooden pieces are connected to make a useful product. Wood is used to make furniture, boxes, doors, windows, industrial floors, stairs, pencils etc.

Carrot (Daucus carota Stova condolle) is one of the most important and widely used root vegetable belonging to the family Umbelliferae. The seed production can be done during September – October in plains and in hills the sowing takes place in June and roots are replanted during the first week of October.

Method of seed production

Carrot is a cross-pollinated crop and self-pollination occurs to the extent of 0-5%. Crosspollination is mainly through insects. Seeds should be allowed to set by cross-pollination in isolation. Seed production is done by seed to seed and root to seed method. In seed to seed method, the matured roots are left to produce flowers and seeds in the place where seeds are sown initially. In root to seed method, roots at edible maturity should be uprooted and the roots of true to varietal characteristics should be selected and transplanted to the well prepared field after proper trimming of roots and shoots. This root to seed method is preferred for seed production in carrot since the root rot infection is high in seed to seed method of seed production.

The isolation distance maintained between the fields of other varieties and the fields of the same variety not conforming to varietal purity requirements for certification is 1000 metres for foundation and 800 metres for certified seed production. During mother root production an isolation of 5 metres should be followed.

Carrot (Daucus carota, 2n = 2x = 18, family Apiaceae or Umbelliferae, cross-pollinated) is among the top ten most economically important vegetable crops globally in terms of area, production and market value (Simon et al, 2008). Almost half of the more than 42 million tons of the global production -by far- is harvested in China, followed by Uzbekistan, Russia and the United States of America. Ukraine, Poland, United Kingdom, Germany, France and Japan complete the top 10.This production comes from approximately an area of 1.5 million ha giving a productivity of 28 tons/ha. India produced 1.6 million tons of carrot during 2017-18 from 96000 ha area resulting into a productivity of 16.66 tons/ha. In India, top 7 states in carrot production are Haryana, Bihar, Punjab, MP, UP, Karnataka and Assam. Because of breeding of cultivars adapted to both summer and winter seasons, carrot is available round the year.

The conventional orange colour varieties of Europe are rich in beta carotene, a precursor of vitamin A and contain appreciable quantity of thiamine and riboflavin. The red carrots are rich in lycopene, an important pigment for healthy eyes and general body growth, besides having anti-cancerous properties. Black carrots are rich in anthocyanins. Further, carrots have medicinal properties.

Carrot has two distinct groups with regard to flowering and seed production. These are tropical and temperate types. Tropical or oriental cultivars are annual and adapted to high temperature conditions and these do not require low temperature exposure for flowering. They flower and set seeds freely in Indian plains after winter months with the advent of long day conditions in spring. The temperate/European types behave like biennial crops and require 6-8 weeks of vernalization at mean temperature of 4.8 to 10° C after they have passed the full root development phase for production of seed stalks (Sureja and Kalia, 2012).

Carrot (Daucus carota L.) is a cool season root vegetable and temperature is the important factor affecting root shape and colour, besides soil type and moisture content of soil. It provides an excellent source of vitamin A and fiber in the diet. The genus Daucus, which include carrot, has many wild forms that grow mostly in the Mediterranean region and South West Asia. Representatives are found in Africa, Australia, & North America. For Daucus carrot L. it is generally agreed that Afghanistan is the primary center of genetic diversity and therefore the primary source for dissemination. Asia Minor, Afghanistan, North West India, Iran and Turkey are the centers of origin of carrot. Banga (1957& 1963) has provided evidence that the purple (anthocyanin) carrot together with a yellow variant spread from Afghanistan to Mediterranean area as early as 10th and 11th century. It is known in Western Europe in 14th and 15th century, China in 14th century and Japan in 17th century. The European carrot (Carotene carrot) derived from the Asiatic (anthocyonin containing) form of carrot (tropical carrot).  Afghanistan is the centre of diversity of the purple coloured carrot (anthocyanin). Integration of Asiatic and European carrots has given the present day forms. The yellow coloured (carotene rich) forms were also thought as mutants of anthocyanin carrots. The yellow mutants were traced in Asia Minor in 10 and 11th centuries, Spain in 12th century, North Western Europe in 14th century and England by 15th century.  The crop was introduced to China during 14th century and to Japan during 17th century. D. carota and D. sativus are only cultivated species of the genera with Chromosome No. 2n = 18. All forms have same chromosome number. 

Carrot, Daucus carota L. under the family Apiaceae (Umbelliferae) having chromosome numbers 2n = 2x = 18 is a root vegetable, grown in spring, summer and autumn in temperate regions and during winter in tropical and sub-tropical regions all over the world. It is important root crop of the European countries, USA, China, Japan, Korea and India. It is grown in almost all parts of India, both in plains and hills. Most of the carrots are typically orange in colour, though purple, black, red, white and yellow cultivars are also available. It is consumed fresh as salad or cooked as vegetable. It is also used for fresh juice, pickles and for the preparation of sweets. Leaves are used as fodder. Essential oil from the seeds is used for flavouring liquors and foods. It contains highest amount of β carotene (pro-vitamin A) among the common vegetables. It is also a good source of vitamin K, and vitamin B6.
Origin, domestication and adaptation in India
Carrot probably originated in Afghanistanin, the region where the Himalaya and Hindukush mountains are confluent. The secondary centres of diversity are probably Ehiopia and north America. Its domestication occurred in Afganistan and adjacent regions of Russia, Iran (previously called Persia), India, Pakistan and Anatolia (Van der Vossen and Sambas, 1993). From its centre of origin in Afghanistan, it was taken by the Arabs to eastern Mediterranean and Spain in 12th century. It was introduced in China in 13th or 14th century, in England during 15th century, in Japan in early 17th century and in the USA in 1620 AD.

The Cartagena Protocol on Biosafety entered into force on 11 September 2003. It is a legally binding international agreement under the United Nations’ Convention on Biological Diversity (CBD).

What is a protocol ?: A protocol is a binding international instrument, separate from, but related to, another treaty. It is a separate instrument, that must be individually negotiated, signed and eventually ratified. It is only binding on States that become parties to it. It thus has its own parties, and creates separate rights and obligations for them, as any other treaty.

The unique characteristic of a protocol is that it is related to a ‘parent’ treaty, through substantive, procedural, and institutional links. Most importantly, a protocol under a specific treaty must comply with the parent treaty’s provisions authorizing and regulating the adoption of protocols under its auspices. 

Introduction

On 29 January 2000, the Conference of the Parties to the Convention on Biological Diversity adopted a supplementary agreement to the Convention known as the Cartagena Protocol on Biosafety. The Protocol seeks to protect biological diversity from the potential risks posed by living modified organisms resulting from modern biotechnology. It establishes an advance informed agreement (AIA) procedure for ensuring that countries are provided with the information necessary to make informed decisions before agreeing to the import of such organisms into their territory. The Protocol contains reference to a precautionary approach and reaffirms the precaution language in Principle 15 of the Rio Declaration on Environment and Development. The Protocol also establishes a Biosafety Clearing-House to facilitate the exchange of information on living modified organisms and to assist countries in the implementation of the Protocol.

Cartography has much back history than what we seen in portable form by its name or definition. Many prehistoric painting of caves had their own time frame record of maps, artifacts and design have been preserved hoping that they are sufficient to the era of forgotten habit and culture, and treasure explicit ancient world. The ancient wall painting of seventh millenium BC, might have indication of oldest maps in the world and the painting is assumed to be the location of ancient city Antolia as Mellaart, depicted 1967. Onward 600 BC, the modern form of cartography started to develop map. The pioneer contribution in map designing and development, old Greek and Roman were main contributor in this direction. One Greek Philoshopher Ptolemmy, multi-talented genius are recalled in this context, who later credited with first documented map of world during production of Geographica, is a treatise on cartography, very soon one Arabian Scholar Muhammad Al-Idrisi prepared a medieval Atlas involving knowledge of world collected by Arabic merchants in 1154.

It is represented by about 100 genera and over 2,200 species which are either annual or perennial, Caryophyllaceae are cosmopolitan in distribution, and mainly found in the north temperate or warm temperate regions of the world. Over 20 genera and about 100 species have so far been reported from India. Some of the larger genera, along with their common names and number of species in parenthesis include Silene (catchfly, 500), Dianthus (carnation, 300), Arenaria (sandwort, 250), Gypsophila (baby’s breath, 125), Stellaria (chickweed, 100), Cerastium (mouse-ear chickweed, 100), Drymaria (50), Spergula (40), Saponaria (30), etc.
Carnation, commonly named as ‘Divine flower’, ‘Clove pink’, and ‘Gilly flower’, is one of the most beautiful and commercially important flower crops of the world. It is excellent for cut flowers, bedding, pots, edging and rock gardens due to its exquisite shape, wide range of colours, light weight and good vase life. In Europe and USA, perpetual carnation is cultivated on large scale in greenhouses for production of cut flowers. In terrain parts of France and Holland, carnation flowers are used for perfume extraction and only light coloured flowers are useful for this purpose.
Description of Family
