Effect of Cadmium on Seed Germination, Seedling Growth and Amylolytic Activity of Rice

doi:10.7668/hbnxb.2008.S1.033

Abstract

Abstract: The effects of different cadmium concentrations on seed germination, seedling growth and amylolytic activity of rice cultivar Xiushui 11 (Oryza sativa L. cv. Xiushui 11) were studied. The results showed that cadmium had litt le effect on germination rate except seeds were treated under high concentration of cadmium. However, germinat ion index, vigour index, root length and amylolytic activity were signif icantly reduced with the increase of cadmium. The inh-ibit ion of cadmium on root growth was more obviously than that on plumula, and the inhibition on the activity of anylase was more seriously than that on anylase.

Key words: Cadmium, Rice, Germination, Root length, Amylase
