Abstract
Absorption of water, loss in nutrient contents and amylase activity of rece seeds during the long-time presoaking treatment were investrgated. The results obtained are as follows : 1) Seeds which are supposed to have strong vitality, as judged from their original location on the mother panicle, are able to absorp water more rapidly than weak grins. 2) The loss of seed contents from the seeds as determined by the decrease of dry-weight during the treatment differs with the different groups of seeds obtained form the different locations on panicle. Sudden inerease of dry-weight loss was observed during April, due apparently to higher temperature. 3) High amylase aetivity was observed in the treated sample of seeds as compared with the control.
