β-环柠檬醛对盐胁迫下黄瓜幼苗生长的影响
Effects of β-cyclocitral on Growth of Cucumber Seedlings Under Salt Stress
摘要
Abstract
In order to clarify the application effect of β-cyclocitral in facility vegetables,the effects of β-cyclocitral(75 μmol·L-1)on the growth of cucumber seedlings under salt stress(150 mmol·L-1 NaCl)were investigated by using'Jinchun No.4'cultivar.The results showed that β-cyclocitral applied in root had little effect on the growth of cucumber seedlings compared with control;while under salt stress,β-cyclocitral treatment could significantly increase the fresh weight,plant height,stem diameter and chlorophyll content of cucumber seedlings,and significantly reduce the contents of MDA and Na+ in roots and leaves of cucumber seedlings,and the content of hydrogen peroxide in leaves decreased by 22.32%and the superoxide anion content in roots and leaves decreased by 21.84%and 28.58%,respectively.In summary,the application of β-cyclocitral can alleviate the damage of salt stress on cucumber seedlings by scavenging reactive oxygen species and maintaining photosynthetic pigment content,and improve the salt tolerance of cucumber.关键词
