कट फ्लावर की कटाई के बाद देखभाल या हैंडलिंग कैसे करें।  In agriculture, post harvest handling is the stage of crop production immediately following harvest, including cooling, cleaning, sorting and packing. Post-harvest treatment largely determines final quality, whether a crop is sold for fresh consumption, or used as an ingredient in a processed food product. The most important goals of post-harvest handling are to keep the product cool, to avoid moisture loss and slow down undesirable chemical changes, and avoiding physical damage such as bruising. Initial post-harvest storage conditions are critical to maintain quality. Each crop has an optimum range for storage temperature and humidity. Also, certain crops cannot be effectively stored together, as unwanted chemical interactions can result. Various methods of high-speed cooling, and sophisticated refrigerated and atmosphere-controlled environments, are employed to prolong freshness, particularly in large-scale operations.  Vase Life of cut flowers:   A fresh flower is still a living specimen even though it has been cut from the plant. The vase life of cut flowers decline due to the following reasons. Inability of stems to absorb water due to blockage Excessive water loss from the cut flower A short supply of carbohydrate to support respiration Diseases Ethylene gas Room temperature and humidity Preservatives are used to extend the vase life of cut flowers. Floral preservatives are very effective in maintaining quality...

फूलों की खेती में प्लांट ग्रोथ रेगुलेटर की भूमिका The use of PGR's in modern horticulture is well established, more particularly horticulture in industrially advanced countries and their application is fast picking up in the developing nations as well. In fact PGRs have become integral component of agro-technical procedures of cultivated ornamental crops, since the regulations for usage of chemicals in ornamental crops are less stringent unlike those in food crops. Thus their application in these crops has been extended to alter a variety of responses. Some plant species or cultivars are responsive to specific PGRs, but not all PGRs. Hormone can be defined as a substance produced in one part of the organism and transferred to another part of the same organism where it affects a specific physiological function. The hormones are required only in minute quantities to produce large specific physiological process. The term growth regulator is applied to organic compounds,  other than nutrients, which when used in minute quantities can either inhibit, stimulate, or alter growth. These broadly grouped in to two, growth promoters which stimulates or alters the growth favourably and growth retardants are those which inhibit or alter the growth negatively. Ornamental crops find extensive use of growth regulators for modifying their developmental processes. Within the broad group of plant...

6 प्रमुख कटफ्लावर की स्वस्थ रोपण सामग्री के उत्पादन की  तकनीक Production of healthy and disease free planting material is difficult task and required lot of experience, planning and management. Since quality planting material (seed/saplings/bulbs etc.) is the basic requirement for successful flower (cut/loose) production for market or exhibition. Generally, plants are produced by two methods i.e. sexual and asexual or vegetative. In India sexual method is followed mostly in flowering annuals (seasonal flowers) and most of the shade, flowering or ornamental trees. Some annual creepers viz., Clitoria ternatea, Cobaea seandens, Lethyrus odoratus, Ipomea spp and Thunbergia alata are also produced from seeds. The other types of plants which are also commonly propagated in our country from seeds are palms, different cacti and succulents. There are several ornamentals which are not normally propagated from seeds but bred by breeders through seed to get new hybrids. Some of these plants are rose, chrysanthemum, gladiolus, carnation, orchid, dahlia, bougainvillea and hibiscus etc. Large number of ornamental plants are also produced through vegetative means like cutting, layering, buddings and asexual organs like corm, bulb and tubers. Therefore, the vegetative production technology of major cut flowers is discussed below in order to facilitate the production of quality planting material. 1. Chrysanthemum Plants are propagated by rooting terminal cuttings....

कारनेशन फूलों की संरक्षित खेती  Carnation is a half hardy perennial with branching stems and tumid joints. Leaf blades are simple, entire and usually narrow. Each stems form a terminal flower and hence inflorescence is generally a terminal cyme. The flowering shoots of carnation are marketed in two forms, standard form and spray or miniature form. Perpetual flowering and green house carnations are of modern origin.  Botanical  Name  : Dianthus caryophyllusFamily : Caryophyllacae Native : Southern EuropeTemperature : Night 14ºC-16ºC,  Day 17 ºC- 22 ºC Crop duration : For Two yearsChromosome no. : 2n=30At present enormous varieties are available with many attractive colours, remarkable ranges of shapes , sizes and delicate fragrance. Types of carnation: Standard type: In  Standard type, flowering buds formed on short lateral shoots arising from the axis of the upper leaves are removed to leave one large, terminal flower on a long leafy stem. It has one large flower on an individual stem. Spray type: In spray type, terminal flower bud is removed at an early stage to encourage  more even development of the lateral flowers, which then produce a multiple flowered stem. Dianthine type :They are more or less similar to the spray varieties, but in this type flowers are smaller and produce more flowers on long stems. Market of these types of carnations is small. Mignon and...

कटाई उपरांत कटफ्लावर का रखरखाव  Floriculture has emerged as a viable diversification option in the agri-business. It is a rapidly expanding industry recording a growth rate of more than 15 per cent per annum in the last two decades.  Rapid urbanization, increased income levels and changes in social values resulted in increase of domestic market both for modern (cut flowers) as well as traditional (loose flowers) flowers significantly. Improvement in the general level of well being in the country and increased affluence particularly among the middle class is also another reason for increase in the volume of local flower market. The quantum of Indian floricultural exports, although, increased manifold since early nineties, still there is huge scope to become a key player in the world flower trade. The floriculture industry in India is characterized by growing traditional flowers (loose flowers) and cut flowers under open field conditions and protected environment conditions respectively. India also has a strong dry flower industry, which contributes a major share to the overall trade. Other segments like fillers, potted plants, seeds and planting material, turf grass industry and value added products also contribute a share in the overall growth of the floriculture sector. At present, the area under flower crops in India is 167000 ha with...
