ABSTRACT
The results of this investigation revealed that cold storage of pea seeds, under different moisture levels, slightly increased their carbohydrate content [in terms of mg per 1 g dry weight]. At the early stages of germination [3-day age] there was no significant effect on the total carbohydrate content of the cotyledons, though 30% moisture treatment tended to reduce starch content whereas, that of the radicle was remarkably low. After 7 days of germination, a drop in total carbohydrates of the whole seedlings of all treatments was obvious, compared with 3-day old stage. This may be due to continued metabolic activities leading to growth. After 15 days from sowing GA3 at 10% moisture seemed to cause a drop in the carbohydrate content of the plant organs and whole seedlings. At 50% moisture, GA3 increased the carbohydrate content of roots and leaves above the controls
