Effects of EMS on Seed Germination of Anemarrhena asphodeloides in the Simulated Environment

doi:10.7525/j.issn.1673-5102.2019.02.010

Abstract

Abstract: The seeds of Anemarrhena asphodeloides were treated with different contents and treatment times of EMS at 1%, 2%, 4%, 6% and 6, 8, 12, 24 h, respectively, in the constant temperature incubator in this experiment.We studied the effects of the different concentrations and treatment time of EMS on the seed germination characteristics of A.asphodeloides. The results of seed germination showed that the seed germination of A.asphodeloides reduced with theincreasings of the contents and the treatment time of EMS. With the relative germination rate reaching the semi-lethal concentration as the standard, the suitable condition for EMS treatment of A.asphodeloides seeds are the concentration of 6% and soaking seeds for 12 and 24 hours.

Key words: chemical mutagenesis, EMS, Anemarrhena asphodeloides, seed germination
