Abstract

The majority of the crop seeds have physiological dormancy after harvesting. This phenomenon is depending to different physiological dormancy. This phenomenon can overcome by pre-treatment including prechilling, pre-heating, dry storage condition, using chemical for promoting germination and overcoming of inhibitor substances. In this study the seeds of two medicinal species (Eruca sativa Lam. and Anthemis altissima L.) under two cold room (4°C) and dry storage (room temperature) conditions were maintained over six months and tested by standard germination test. The physiological quality of the seed rocket plant had not any significance differences in two conditions.
The reason might be due to non-physiological dormancy of the seed species. Whereas, percent of germination in the species of chamomile was significant in the two conditions. As it is clear the percent of germination of the chamomile from dry storage condition was higher from cold room condition and this due to physiological dormancy of plant seed which overcome by dry storage condition. The speed and vigor index of plant seed had no significant differences in two conditions.
