Abstract
Excised embryos of aged non-germinating wheat seeds, when placed on sucrose/glucose germinated well and grew into normal plantlets, while on agar alone they remained ungerminated as in the intact seed. From the results of amylase assays in seeds of different ages it appears that failure of amylolytic activity in aged seeds could be a cause of unavailability of utilizable subtrate to the embryonic axis of aged seeds. This would bring about a limitation in the capacity of germination and growth of the embryonic axis even before the embryo becomes non-viable.
