外源赤霉素对盐胁迫下甜玉米幼苗生理性状的影响
|
摘要
以华宝甜8号甜玉米品种为实验材料,在盐胁迫条件下对其进行外源赤霉素的叶面喷施,研究苗期甜玉米鲜重、叶绿素含量、过氧化氢酶(CAT)及超氧化物歧化酶(SOD)活性的变化。结果表明:外源赤霉素的喷施能够缓解盐胁迫对甜玉米幼苗各项生理性状的抑制作用。
In this study,sweet corn varieties Huabaotian 8 as experimental material,it was sprayed on the leaves with exogenous gibberellin under the condition of salt stress to study the changes of fresh weight,chlorophyll content,CAT and SOD activity of sweet maize seedling.The results showed that the spraying of exogenous gibberellin could alleviate the inhibition of salt stress on the physiological characteristics of sweet corn seedlings.
