水稻品种中VC含量及抗氧化性的比较分析
Comparative Analysis of Vitamin C Contents and Anti-oxidization in Rice Varieties
摘要
Abstract
Vitamin C (VC), also known as ascorbic acid (AsA), is a pivotal antioxidant in response to plant oxidative stress. Many research results have revealed that VC functions in resistance to oxidative stress in different plant species including Arabidopsis and wheat, but little is known in rice. In this paper, the VC contents in rice varieties Zhonghual7, Nipponbare, Yangdao6 and Yangdao 2 were compared, and found that their VC contents were obvious different. Combining with the treatment of MV ( Methyl Viologen), changes in superoxide anion and H2O2 levels among these varieties were also compared. The results showed that there was close relationship between VC contents and oxidative stress resistance of rice. Those results proved that VC played an important role in rice resistance to oxidative stress, which provided a basis for improving rice resistance to stress.关键词
