Incorporation of labelled amino acid C-14 in three varieties of sorghum; IS-13, IS-9327 and 1S-3541 was studied. Varieties IS-13 and IS-9327 are capable of regermination, even after having an initial germination followed by a drying period of ten days. These two drying resistant varieties can incorporate more amino acid C-14, as compared to non resistant variety (IS-3541), which could not germinate after drying.
