外源ALA对常温和高温条件下裸燕麦生长发育及抗氧化酶活性的影响
Effect of 5-Aminolevulinic Acid on Growth and Antioxidant Enzyme Activities of Avena nuda under Normal and High Temperature Conditions
摘要
Abstract
A pot test was conducted to study the effect of ALA at different concentrations (0,10,50,100 mg/L) on the growth and antioxidant enzyme activities of Avena nuda under normal and high temperature conditions,so as to provide some references for improving productivity and heat resistance of Avena nuda.The experimental results revealed that the plant height,leaf length,leaf width,leaf area,dry and fresh weight,chlorophyll a content,carotenoids content,chlorophyll a/b and the activities of SOD,CAT,POD of leaves were increased with the application of ALA for Avena nuda under room temperature condition.Among them,the leaf area,leaf width,dry and fresh weight,SOD and POD activities of 50 mg/L ALA treatment were the highest;the plant height,leaf length,chlorophyll a content,carotenoid content,chlorophyll a/b and CAT activity of 100 mg/L ALA treatment were the highest.The growth of Avena nuda was inhibited under high temperature stress.Spraying ALA could decrease the harm of high temperature stress to Avena nuda,and spraying 50 mg/L ALA had the best effect.The plant height,leaf area,leaf length,leaf width,dry and fresh weight,chlorophyll a content,carotenoid content,chlorophyll a/b and SOD,POD,CAT activities of 50 mg/L ALA treatment increased by 13.0％,43.6％,53.5％,39.6％,116.4％,34.5％,54.5％,21.8％,47.4％,19.1％,38.9％,105.4％ compared with the treatment with out ALA under high temperature stress.关键词
