Bangladhonia seed germination was tested in the field after stored in normal and low temperature with different seed treatment at different times. The rates of seed germination in all treatments were decreased gradually with the increased storage period from January to April with increasing temperature during germination period. Growth regulator (GA3 500 ppm + Kinetin 50 ppm) treatment resulted better germination performance in every sowing than fungicide (Bavistin) treatment or control (distilled water). After one year of storage, a good number of seeds were germinated only from low temperature storage. The maximum number of seedlings (258) germination percentage (20.22%) were found in low temperature (4-50C) storage with growth regulator treatment.

Variety and Species
To identify the suitable storage condition for increasing storage life and viability retention and to improve germination using growth regulators.
The experiment was conducted at the Horticulture Laboratory and Experimental Plot of Bangabandhu Sheikh Mujibur Rahman Agricultural University during November 2007 to March, 2009.The experiment was laid out in RCBD (factorial) design with three replications having two levels of storage temperature viz. T1: Normal temperature T2: 4-50C in refrigerator, and three levels of packaging materials viz. P1: Brown paper, P2: Sealed poly bag, P3: Cotton bag. The land was prepared finely to have a good tilth as seedbed. Well rotten cowdung, N, P an K were applied @ 15 ton, 25 kg, 60 kg and 60 kg per hectare during final seedbed preparation. About 0.5.g (1280) of seeds/plot were broadcasted and mixed with the surface soil on 15 December, 2007. The number of healthy seedlings counted in each plots for every sowing at 45 days after sowing when maximum number of seedlings were noticed. Germination percentage was calculated from the number of seedlings and number of seeds sown in each plot.

The major cause of low germination of seeds in March, April and May sowing is due to high temperature during the germination period rather than the reduction of viability of seeds. The germination rate rapidly deteriorated in those seeds that were stored under low temperature and sown in high temperature. It is possible to remain the seeds viable for one year by storing under 4-50C temperature that might give an acceptable germination if sown in optimum (12 - 20 0C) temperature.
