不同保水剂处理对辽西地区油松苗木耐旱性的影响

摘要

Taking common Pinus tabuliformis seedlings in western Liaoning Province as research objects,the effects of water-retaining agent on drought tolerance of Pinus tabuliformis seedlings were studied.Result shows that after the treatment of adding S and K type water-retaining agent,relative water content (RWC)and MDA content of leaves of Pinus tabuliformis seedlings significantly change compared to the CK;drought tolerance of seedlings was increased.%以辽西常见的油松苗为试验对象，研究了添加保水剂对油松苗耐旱性的影响。结果表明：添加 S 型和 K型保水剂处理后，油松幼苗叶片内的相对含水量和 MDA 的含量较对照发生显著变化，能明显提高幼苗的耐旱性。
