摘要:
以3年生“烟富3”幼树为试材，通过盆栽试验，研究了水分胁迫过程中叶面喷施硅对苹果幼树叶片中相对含水量（RWC）、脯氨酸、丙二醛（MDA）含量以及超氧化物歧化酶（SOD）、过氧化氢酶（CAT）活性的影响。结果表明：在水分胁迫过程中，喷施硅预处理能有效缓解轻度胁迫条件下的叶片相对含水量的减少、降低丙二醛含量、增加脯氨酸含量、提高抗氧化酶活性，但在重度胁迫条件效果不明显。
Abstract:
Taking three-year-old potted cultured ‘Yanfu 3’ apple trees as material，the effect of spraying silicon on content RWC，proline content，MDA content and antioxidant enzyme activity(SOD activity，CAT activity) were studied under drought stress by pot experience.The results showed that exogenous silicon alleviated the RWC decreasing，increased the proline content，increased the activities of SOD and CAT，decreased the MDA content under the slight stress.There was no different effect under the severe water stress.
