Title: Effect of Different Chemicals and growth regulators on Vase life of Oriental and Asiatic Lilies Authors: T, Usha Bharathi; D, Burman; N, Buragohain; S K, Naik; R P, Medhi Abstract: The investigations were carried out to extend the post harvest life of oriental lily hybrid Solaila and Asiatic lily hybrid Voltage. The various concentrations of chemicals significantly enhanced the water uptake, fresh weight, appearance and vase life of lily spikes. The treatment with Sucrose 2% + 8-HQ 150 ppm + GA3 100 ppm was significantly superior to other treatments and control. It recorded significantly maximum vase life of 14.75 days as compared to control (12.50 days) and proved best treatment for prolonging the vase life of oriental lily hybrid Solaila. Pulsing of spikes with STS 0.5 mM + 8-HQS 200 ppm + Sucrose 8 % significantly increased the post harvest life of Asiatic Lily hybrid Voltage.

Title: Post harvest management of Cymbidium Authors: T, Usha Bharathi; D, arman; S K, Naik; L C, De; R P, Medhi Abstract: Cymbidium is the top one among all orchids in the global trade. It fetches highest price in the international market. The post harvest management and handling of cymbidium is important as quality improvement in order to compete in world market. Cymbidium orchid’s spikes possess the vase life of 4 to 6 weeks. Cymbidiums are sold as whole cut spike or as individual blooms. Pre harvest factors are having direct influence on the post harvest life of cymbidiums. Cymbidium flowers should be protected from the all sorts of weather damage, pollinators and insect pests. The spikes are needed to be trained for the production of straight quality spikes. Cymbidium orchids should be harvested 3-4 days after opening of all florets on the spike. While harvesting utmost care should be taken to protect the pollen cap of the flower, it should be intact with the flower. The harvested spikes require precooling; it needs to be dipped in bucket of water immediately after harvest. In order to improve the quality and vase life of flowers spikes, the cut spikes should be subjected to pulsing with sucrose at the rate of 2-4%. Sucrose in keeping solutions as a carbon source may extend the vase-life of orchid cut flowers. And a combination of biocide, sugar and hormone remarkably enhances the post harvest life of the Cymbidium hybrids. The flower spikes of Cymbidiums are first sleeved in polyethylene sleeves of standard thickness. Flowers should be graded and checked before they sleeved. Cymbidium flower spikes are normally packed in carton or telescopic boxes. Mixed colour boxes are preferred over pure or mono colour boxes. Cymbidium spikes may be stored at lower temperatures, even at 5 0C in cold chambers.

Title: Exploration And Germplasm Collection Of Rose Species From Sub-Himalayan And High Altitude Himalayan Region Authors: M V, Dhananjaya; K, Pradheep; D, Dhyani Abstract: An exploration was undertaken during the month of April 2008 to collect variations available in wild, naturalized and cultivated forms of rose belong to the genus Rosa. The exploration team comprised of scientists from three organizations NBPGR Regional Station, Shimla, Indian Institute of Horticultural Research, Bangalore Karnataka and Institute of Himalayan Bioresources Technology, Palampur, Himachal Pradesh. The areas covered during the exploration belong to Zone VI of Himachal Pradesh (NW Sub-Himalayan and high altitude Himalayan Region). Sampling for specific traits, selective sampling was made. Random sampling was made in case of wild population of high altitude plants with the aim of making them acclimatize under Shimla condition as a first step. Forty two accessions belong to 16 different species were collected during the exploration. The collected species include, Rosa multiflora Rosa brunonii, Rosa moschata, Rosa chinensis, Rosa beggeriana, Rosa gallica, Rjosa laevigata, Rosa x alba, Rosa ax fortuniana, Rosa fortida, Rosa banksiae, Rjosa macrophnylla, Rosa sericea, Rosa wichuraiana, Rosa x borboniana and Rosa 'Hybrida'. Role of women and local people in conservation, utilization of plant diversity and holding associated indigenous knowledge was well witnessed in all the area covered. Most of the houses were decorated with modern cultivars of rose in their home garden while the obsolete cultivars find place in boundaries, field ends, as live fence, a roadside which is a healthy sign in terms of conservation. Overall we could find about 50 different types of cultivated roses averaging 3-4 types per house in all those areas surveyed. The details of the Physiography, Agro-climatic conditions and common vegetation of the area surveyed. Nature and extent of diversity, variability patterns, breeding potential of collected genotypes and other important issues were illustrated in this paper.

Title: Post-harvest life of gladiolus cv. Jester Gold as influenced by different doses of nitrogen, phosphorus and potassium Authors: Rajiv Kumar; R L, Misra; S K, Singh Abstract: The influence of different doses of nitrogen, phosphorus and potassium on gladiolus cv. Jester Gold was studied in a field trial conducted by factorial randomized block design. The effect of nitrogen (20, 40, 60, 80 g/m2) with phosphorus (5,10,20 g/m2 ) and potassium (15,20,25 g/ m2) and control applied to the plants on post-harvest life of cut gladiolus spikes were studied under laboratory conditions. Longevity of first floret was increased by application of N80 P5 g/ m2. A dose N60 K20 and N80 P10g/ m2 was producing bigger first and third fully opened floret, respectively. Application of N80 K20 g/ m2 resulted into maximum fully opened florets and total florets/spike in the vases. Effective useful life, vase-life, water uptake on third day and at senescence in the vase was increased by the use of N60P20g/ m2. A fertilizer dose of N80P20g/ m2 resulted into maximum increment of spike length at senescence, fresh weight of spike at harvest, at third and fifth day in the vase.
