Abstract

Sorghum bicolor seeds germinated immediately after harvest, whereas those of S. halepense failed to germinate in light or dark at 15, 26 or 30 deg C, after prior cold treatment (4 deg ) or heating, following treatment with GA or thiourea after prior cold treatment, after prolonged rinsing, or after removal of the glumes. Removal of the glumes, however, resulted in 80% germination in seeds stored at room temp. for 3 months. At germination, metabolism in S. halepense seeds was more rapid than in S. bicolor seeds as indicated by loss of dry wt., starch and protein and formation of soluble sugars and soluble protein. A method for determining the potential for cyanide liberation is described. In seedlings the potential for cyanide liberation in S. halepense was only about 25% of that of S. bicolor on a per seedling basis; however, per g seedling dry wt., the potential was >50% higher in S. halepense and the build-up of cyanide liberation potential was much more rapid. The results indicated that S. bicolor was slower in all the processes leading to seed germination than was S. halepense
