维生素B1对油菜氧化胁迫的调节作用
Regulation Function of Vitamin B1 on the Oxidative Stress in Brassica campestris L.
摘要
Abstract
[Objective]The purpose was to study the effect of VB1 on methylviologen (MV)-mediated oxidative stress injury of seedlings of Brassica campestris L. [Method] With the seeds of B. Campestris as the tested materials, they were treated by 4 kinds of medium of MS, MV, VB1 and MV+VB1 with different concn.. Fresh weight of seedlings and SOD, CAT and APX activity, as well as content of malondialdehyde (MDA) and proline (Pro) in B. Campestris plants dealt with different treatments were measured to study the effect of VB1 on alleviating the oxidative stress in seedlings of B. Campestris. [Result] MV could inhibit the growth of B. Campestris plants, induce the increase of contents of MDA and Pro as well as contents of CAT, SOD and APX enzyme activity in plants; VB1 could alleviate the MV-mediated oxidative stress injury in B. Campestris seedlings to some extent. The remission extent was related to concn. Of VB1 and the alleviating effect was the best when VB1 was 2.0 mmol/L. [Conclusion] VB1 had certain regulation on MV-mediated oxidative stress in seedlings of B. Campestris and the remission extent was related to concn. Of MV and VB1.关键词
