Abstract
Model of seed storage behavior has high importance for seed conservation. With determination model of seed storage behavior, collection and conservation of plant seed would be recognized. If the plant seeds have orthodox behavior, their conservation will be carried out in out of provenance and it is termed as Ex- situ conservation. If the plant seeds have recalcitrant behavior, their conservation would be done within provenance and it is termed as In situ conservation.
In this research, model of seed storage behavior of some medicinal plant seeds were studied. The seed samplesof some medicinal plants from different state of country were processed and analyzed. The processing of the seed samples included physical and genetic purity, seed healthy test, thousand weight, moisture content determination, germination test, packaging and conservation of the seed samples in cold room of gene bank. Evaluation and determination of model of seed storage behavior was the major point of this research work. By determination of moisture content, the model of seed storage behavior of medicinal plant seeds was identified and most of them have orthodox seed storage behavior. Therefore their conservation should be done as Ex- situ conservation.
