The seeds of Bangladhonia (Eryngium foetidum) stored in normal and low temperature with different packing systems and germination of seeds were tasted in the field after different periods of storage. The germination rates of seeds in all packaging were decreased gradually with the increased storage period from January to April. After 5 months storage, in April sowing, sealed polybag exhibited better germination (4.14%) than brown paper (1.78%) and cloth bag (1.51%) whereas after one months storage the germination percentage were 32.33, 30.97 and 31.38, respectively. After one year of storage an acceptable number of seeds from low temperature storage were germinated. Low temperature (4-50C) storage with sealed ploybag packing was found better for storage of Bangladhonia seeds. After one year storage the maximum number of seedlings (258) germination percentage (20.22% ) were found in low temperature (4-50C) storage, sealed polybag packing.

Variety and Species
i) identify the suitable storage systems for increasing storage life and viability retention of Bangladhonia seeds and ii) to study the possible storage potentiality up to an acceptable germination level.
The experiment was conducted at the Horticulture Laboratory and Experimental Field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh 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. After sowing the beds were covered with dry straw and frequent irrigation was provided by watering can with finely meshed nozzle to keep the soil and mulch moist. The straws were removed and weeding was done at the 21 days of seed sowing when few seedlings are visible on soil surface. All the activities were repeated at 15th of every month interval i.e. December (2007), January, February, March, April and May (2008). After May, 2008, the process was stopped when no seeds were germinated.

After one year storage the maximum number of seedlings (258) germination percentage (20.22% ) were found in low temperature (4-50C) storage, sealed polybag packing.
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. Changing the previous idea, it was found that Bangladhonia seeds could be stored for one year under low temperature with sealed polybag (air tight) packing.
