摘要
采用盆栽试验 ,研究了在模拟干旱胁迫下几种植物生长调节剂对玉米幼苗生长的影响。结果表明 :喷施植物生长调节剂可促进玉米幼苗的生长 ,苗高、根长、根数、叶面积、根冠较对照有明显增加 ,同时还提高了幼苗的叶绿素含量、脯氨酸含量和过氧化物酶活性 ,使植株的抗旱能力增强。喷施黄腐酸盐效果最好。
Spraying plant growth regulators on maize seedlings under drought stress could promote the growth. The results indicated that the plant growth regulators could increase plant height, root length, root number, roog-cap ratio, chlorophyll content, proline content and the activities of superoxide dismutase(SOD), and improve the ability of drought-resistance of maize seedlings.
