The seeds of Ailanthus excelsa exhibited orthodox storage behaviour as viability period increased with the decrease in storage temperature and seed moisture content. Seeds dried to 5.7% moisture content remained viable, with 50% of the initial germination, beyond three years at 5°C and beyond one year at ambient room temperature. The seeds are non-dormant and germinate freely at 30°C on top of paper, the conditions found ideal for testing germination capacity.

Studies were conducted on factors atrecting germination and longevity of Alnus nepalensis and A. nitida seeds under laboratory condition. Germination in both the species commenced on the 7th day and was completed by the 28th day. A. nitida germinated equally well at 20° or 25°C on TP, BP or TS A. nepalensis germinated equally well on TP at all temperatures, i.e. 20,25,20/30°C or 30°C but was best at 25 in BP and on TS at 20/30°C. Seed emptiness was found one of tbe major causes of poor germination in both the species. Though both the species exhibited variations in germination and longevity but in general the trends were almost similar. Seeds of both tbe species were found short-lived in nature.- Fruit Maturity And Interrelated Effects of Temperature and Container on Longevity of Neem (Azadirachta indica) Seeds

Fruits of neem were collected at different intervals of maturity. Physiologically mature seeds with maximum germination capacity and longevity were obtained 10 to 12 weeks after flowering (late July to early August) when some of the fruits turned yellow and started falling on the ground. This period coincided with peak green weight, size and a fully grown embryo enclosed in bard fibrous endocarp. Seeds were also stored at room temperature, 15°C and 5°C in sealed polythene bags, perforated polythene bags, perforated cardboard boxes (seeds wrapped in blotters) and over silica gel in desiccators. It was found that sealed containers and low temperature (5°C) are responsible for rapid deterioration of seeds while well aerated containers inhibited deterioration upto certain extent at room temperature and 15°C till 6 months.- Preliminary Studies on Seed Germination Behaviour Berberis lycium, Royle-an Important Shrub for Reclamation of Wastelands in the Himalaya

Seed of Michelia champaca were treated variously to enhance germination. All coat softening treatments failed to improve germination. Little improvement in germination was observed in seeds prechilled at 5°C. Gibberellic acid was found effective in promoting total germination as well as speed of germination in terms of germination value.- Investigation on the Seed of Michelia champaca Linn. for Perfection of Optimum Conditions of Storage

This paper presents the results obtained after investigation on the seed storage of Michelia champaca. The seeds of this species are very short-lived, under natural environmental conditions. The seeds were stored in different containers at room temperature and at low (5°C) temperature. The results revealed, that the seeds stored in well aerated containers at low temperature retain germination capacity till the end '8' months. The best results were exhibited, by the seeds stored in perforated polybags, followed by Markene bags.- Effect of Temperature and Containers on Holoptelia integrifolia Planch Seeds for Maximum Retention of Viability and Vigour

Seeds of Holoptelia integrifolia rapidly loses viability if not properly stored. Under field conditions, seed deterioration can be inhibited upto certain extent provided sealed containers are used storage preferably with silica gel.- Preliminary Studies on Germination and Longevity of Carissa opaca, Stapf.

Seeds of Carissa opaca are non-dormant and germinate pronmptly without any treatment.Extracted seeds exhibited better germination as compared to the fruits. There is no statistically significant difference in germination capacity of fresh black and green seeds, but green seeds lost germination capacity within 2 months in open storage at room temperature while black seeds exhibited negligible deterioration eveo after 6 months.Keywords
