The plant is propagated vegetatively through corms and cormels, but due to low rate of multiplication, its cultivation is hindered. Also, it is grown through underground modified stems, they are more often attacked by soil borne diseases such as Fusarium corm rot. In-vitro propagation techniques, assumes significance, especially for securing rapid multiplication of quality planting propagules using dormant cormlet explants and media. The results of the study revealed that the MS growing medium supplemented with 2 mg/l BAP showed improved results in respect of sprouting of explants (54.46 %), days required for sprouting of explants (8.68 DAI) and shoot length at 30 (6.32 cm), 60 (12.40 cm) and 90 (13.21 cm) DAI. The in vitro regenerated gladiolus plantlets when placed in the rooting MS medium supplemented with 4 mg/l IBA showed earlier root initiat...

Now a day’s organic cultivation practices have immense potentiality due to huge demand as because it resulted low health hazards as well as gave pollution free environment and improved soil fertility. The experiment was laid out by following Factorial Randomized Complete Block Design, consists of two factors in which first factor was varieties (Pusa Bahar-V1 and Pusa Narangi Gainda- V2)and second factor was ten treatments combination. Different Organic nutrients like Farm Yard Manure (FYM), Vermicompost, Poultry Manure, Sea W...

Knowledge on host-pathogen interaction is a prerequisite for the sustenance of any breeding programme related to Fusarium resistance as it is responsible for novel product development, protection and utilization. With the recent upsurge of global floritrade, research efforts are focussed towards the development of disease-resistant cultivars utilizing conventional techniques like selection, introduction and hybridization and non-conventional techniques like marker assisted selection, soma clonal variation, in-vitro and genetic engineering. Hybridization and selection proved promising in developing wilt resistant cultivars of gladiolus. Gametophytic self-incompatibility is an innovative approach in carnation in this reg...

Apart from nutraceuticals and phytomedicinal properties, cucurbits are rich in several minerals, vitamins and dietary fibres. Homestead gardens are traditional ex-situ conservation sites for crop biodiversity. The agro-climatic condition of sub Himalayan West Bengal is ideally suited for cultivation of different cucurbitaceous vegetables including cucumber, bottle gourd, pumpkin, ridge gourd, sponge gourd, pointed gourd, spine gourd, ash gourd, bitter gourd, snake gourd, water melon, muskmelon, chow chow, ivy gourd etc, a majority of which are available in homestead gardens. Among individual crop, variability exists in fruit shape, fruit size, fruit colour, fruit length, fruit lustre, stem shape, seed size, 100 seed weight etc. The rich diversity remains unexploited for crop improvement, which may offer tremendous scope for utilization in food and nutritional security. These plants are having wide ethnomedicinal ...

So, post-harvest management is the important part of floriculture sector. Pre-harvest, Post-harvest and Harvesting (Stage of harvesting, Time of harvesting, Method of harvesting) is strongly related to self-life of flowers and ornamentals. Flowers and ornamentals should be harvested at a proper time, otherwise loss of quality and self life. Some example is Rose (Tight bud stage), Marigold (Fully opening Stage), Orchid (3 to 4 days after full opening of flower), lilium (Bud colour show red) and others. Major advantage of post-harvest management is throughout the year flower supply, Farmer can get more profit, Crops spoilage is very low and more employers also involve under post-harvest industry but, some physiological disorder also found during post-harvest condition such as; calyx splitting of carnation, Bent neck of rose, Bud...

Jewel has been developed through callus induction and organogenesis using leaf lamina as explant. MS basal medium containing 3 mg L-1 2,4-D + 0.5 mg L-1 BAP + 0.4 mg L-1 TDZ took minimum number of days (37.68) to initiate callus. However, maximum callus production was observed in the media containing 2 mg L-1 NAA (77.33%). Young leaves exhibited better responses and the calli were compact and dark green. The shoots were initiated later from the calluses by inoculating on MS media containing 3.0 mg L-1 BAP + 0.5 mg L-1 NAA which took a minimum of 27.83 days while MS + 2 mg L-1 BAP + 0.5 mg L-1 NAA gave highest regeneration percentage (98.89%) as well as shoot length of 2.23 cm. Maximum number of shoots per callus (5.83) and highest number of shoots following second subculturing (22.60) were observed when MS basal medium was fortified with 2 mg L-1 BAP singly. For root induction, 1/2MS media supplemented with 2.0 mg L-1 NA...

An experiment was conducted to study the effect of Gibberellic acid (GA3), NBenzyl adenine (BA) and Triacontanol each at 25 ppm, 50 ppm and 100 ppm on the biochemical changes in the corms of Gladiolus (Gladiolus grandiflorus L.) cv. American Beauty following RBD with 10 treatments replicated thrice grown at Uttar Banga Krishi Viswavidyalaya, India from October, 2013 to April, 2014. Application of GA3 @ 50 ppm increased nonreducing sugar content of corms (0.665 mg/ g of fresh weight) and corm protein content (6.02 mg/g of fresh weight) whereas, Triacontanol @ 50 ppm improved phenol content of corms (1.07 mg/g of fresh weight) but, Triacontanol @ 100 ppm improved the reducing sugar content (4.089 mg/ g of fresh weight) and enzyme activity of corms (2.73 ∆490nm/min/g fresh weight).

The treatments consist of ten different concentrations of GA3 with a control. GA3 treatment at 250 ppm resulted in significantly better performance in relation to plant height (87.87cm), number of branches (13.37), number of leaves (36.01), plant spread (40.92 cm), whole biomass (447.10 g), fresh shoot weight (355.69 g), fresh root weight (92.10 g), days to flower bud initiation (52.93 days), flower longevity on plants (6.67 days), duration of flowering (24.4 days), number of flowers/ plant (53.12), diameter of flowers (6.79 cm) and expected flower yield (52.28 MT/ha). The same treatment was also effective in improving biochemical constituents like leaf chlorophyll content (54.60 SPAD), protein content (1390.5 µg/g), carotenoids (370.8 mg/Kg), carbohydrate (2...

The plant height at 15 days interval starting from 30 days after transplanting (DAT) was found greater in polyhouse condition than open-field cultivation. Petunia showed the maximum plant height (133.99cm) under polyhouse and minimum plant height was recorded in Daisy (26.08cm) at 75 DAT under open-field condition. Earliness in flower bud initiation (23.25DAT) was observed with Calendula officinalis under open-field condition and the delayed flowering was observed with Antirrhinum majus (74.67DAT) under protected condition. Candytuft took minimum time period to reach FBD from FBI (6.17days). Lupin required minimum time...

The motive of this work was to estimate the physicochemical properties, macro and micro nutrient content and various microbial load of Kunapajala with different storage time interval. Kunapajala had the highest P, K, Ca, Mg, Fe, Zn, Cu & Mn 40 days after preparation and it had highest N and S 20 days after preparation. It had the highest beneficial microbial load of Fungi, Actinomycetes, Pseudomonus, Phosphorus Solubilising Bacteria (PSB), Azotobacter, Azospirillum, Rhizobium and Trichoderma 40 days after preparation. So, continuous foliar and soil application of Kunapajala from 20 days after preparation to 40 days after preparation was beneficial to get maximum utilization.
