Seeds of Aesculus indica shown immediately after collection in the month of October-November resulted in poor germination. In natural conditions, seeds took about 4-5 months to germinate. Stratification of seeds for 15 or 30 days resulted in enhanced germination percentage as well as shorter mean time to germination (M.T.G.). In the laboratory,the seedlings grown in pure sand medium showed hyper-elongation due to etiolation but survived transplanting in polypots, following hardening in a shaded place for a couple of days. There was no significant effect of stratification on seedlings growth. A. indica seeds required a brief period of chilling and subsequent higher temperature during incubation for accelerating the germination and seedling growth.

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.- Maturity Indices and Pre-treatment Studies on the Seeds of Ficus benjamina

This is very essential to determine the exact time of maturity of seeds, as the longevity of seeds and their germination are highly influenced by it. The present paper deals with the result obtained on the investigation of maturity indices and pre-treatment studies on the seeds of Ficus benjamina. The study reveals that brownish yellow stage of maturity gives better germination results than the other stages. At the moment seeds devoured by bats are considered best for germination. The study disapproves this.- Germination Behaviour of Prinsepia utilis Royle: an Important Shrub for Reclamation of Wastelands in Himalayas

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

Experiments were conducted to findout the effect of solar eclipse on seed germination of Dolbergia sissor and Toona ciliana. Seeds of both the species, preimbibed for various durations, were exposed to eclipsed and unclipsed sun prior to germination. The germination period of both the species was extended significantly after the exposure to eclipsed sun without affecting tbe total germination significantly.- Storage of Dendrocalamus strictus Nees, Seed for Maintenance of Viability and Vigour
