Endogenous Inhibitors of Celosia argentea L.Seeds
An experiment was conducted to study the inhibitory activity of the aqueous extracts(different concentration,extracting times,extraction time and years)from Celosia argentea L.seeds on seed germination and seedling of Brassica chinesis in order to prove the endogenesis inhibitory substances in seed of C.argentea.Results showed that the extracts could significantly inhibit seed germination(5.32%)and root length(0)when the extracting concentration was 1.4 g/mL and the inhibitory activity would be enhanced with increasing concentration,time and extracting times.Seeds of different years had different inhibitory effect,the inhibitory effect of fresh seeds was stronger than that of aged seed.The results suggested that the seed of C.argentea probably had strong endogenesis inhibitory substances.
