干旱胁迫对剑麻幼苗生理生化的影响
Effect of Drought Stress on Physiology and Biochemistry of Sisal Seedling
摘要
Abstract
Pot cultivation experiment was used to evaluate the effects of drought stress on the physiology and biochemistry of sisal seedlings. In this study, sisal seedlings were exposed to drought stress (without irrigation)for 90 days. And the measurement was determined every 15 days, including leaf relative water content ( RWC ), relative electric conductivity ( REC ), malondialdehyde ( MDA), peroxidase (POD) , proline(Pro) and root activity(TTC). The results indicated that RWC decreased by the biggest rate of 8. 64% with the increasing of the stress time. However REC, MDA and Pro increased evidently, and the corresponding biggest increased rates of REC and MDA and Pro were 86.22% , 80% , 41.54% , respectively. Meanwhile, POD and TTC activities increased at the beginning and then declined continually in the later. The highest values of the POD and TTC activities were 1326. 33u/g. Fw and 2. 66g/g. h respectively.关键词
