Effects of GA3 Treatment on Germination of Amorphophallus bulbifer Seed
摘要
Abstract
To explore the effect of gibberellin on seeds germination in A.Bulbifer,the seeds were treated by using different concentration gradients of gibberellin.Additionally,seed germination percentage and biochemical change were analyzed during the germination.The results showed that the percentage of seed germination was increased from 72％ to 98％ under the treatment of 50 mg/L gibberellin.During seed germination,in the control group,the length of hypocotyl increased from 0.4 cm to 1.6 cm,the soluble sugar content increased from 7.633 mg/g to 9.551 mg/g and soluble proteins increased from 9.668 mg/g to 10.408 mg/ g;in the test group,the length of hypocotyl increased from 0.4 cm to 1.6 cm,soluble sugar content increased from 7.798 mg/g to 10.153 mg/g and soluble proteins increased from 9.611 mg/g to 10.441 mg/g.The results suggested that gibberellin could increase the decomposition of organic material in the seed,which could promote seed germination.关键词
