| 摘 要： | 以辣椒幼苗为试材,采用盆栽控水的方法,研究干旱胁迫下芸苔素内酯(BR)对提高辣椒幼苗抗旱性的效应。结果表明:经过BR和水分胁迫同时处理的辣椒幼苗叶片组织水含量、可溶性糖含量、过氧化氢酶(CAT)、过氧化物酶(POD)、脯氨酸含量和叶绿素含量都较对照高;质膜相对透性和丙二醛(MDA)含量则相反,表明BR能提高辣椒幼苗的抗旱性。

| Abstract: | Used the pepper seedlings as experimental material,a method of controlling water usage of plants was carried out to study drought stress of the BR,in order to improving the effects of drought resistance of pepper seedlings.The results showed that after BR and water stress at the same time dealing with the tissue water content of pepper seedlings, soluble sugar content,catalase(CAT),peroxidase(POD),proline content and chlorophyll content was higher than those without BR treatment,while the relative plasma membrane permeability and MDA content in contrast,it showed that BR can improve the drought resistance of pepper seedlings. |
