京尼平苷对盐碱胁迫下马铃薯试管苗渗透调节和抗氧化能力的影响
Effects of Geniposide on Osmotic Regulation and Antioxidant Capacity of Potato Plantlets under Saline-alkali Stress
摘要
Abstract
To study the effect of geniposide on the biochemical and physiological mechanism of potato under saline-alkali stress,the salt alkali tolerant variety'Kexin No.1'and salt alkali sensitive variety'Shepody'were studied in this study,the potaoto plantlets under saline-alkali stress were cultured with different concentrations of geniposide for 28 days.The contents of osmoregulatory substances and the degree of membrane lipid peroxidation of potato plantlets leaves were measured.Meanwhile,detecting changes in antioxidant enzymes activity and non-enzyme antioxidants content in the antioxidant defense system.The results showed that:in a certain range of concentration,geniposide treatment could effectively alleviate the inhibition degree of saline-alkali stress on potato plantlets in vitro.That can promote the increase of soluble protein,soluble sugar and proline content in the leaves of potato plantlets,allowing for the accumulation of osmotic substances and maintaining osmotic regulation balance.It reduces malondialdehyde content,and increase antioxidant enzyme activity and GSH content.The results indicated that geniposide could improve the saline-alkali stress resistance of potato plantlets in vitro.This study provides a theoretical basis for the application of geniposide in stress-resistant potato production.关键词
