摘要
在冬小麦三叶期对叶片喷施不同生长调节剂 ,研究其对冬小麦冬前生理生态的影响。结果表明 :不同生长调节剂可以明显影响小麦分蘖节中内源激素含量及相互间的平衡 ,并对小麦的分蘖力产生明显影响。PP333和 6-BA处理的小麦冬前群体数分别比对照提高了 1 0 %和6%。同时 ,PP333和 6-BA还能够提高小麦叶片硝酸还原酶活性 ,并使叶片维持较高的叶绿素含量。
Researches on the effects of growth regulators sprayed on wheat leaf at 3-leaf stage on the physiological ecology of winter wheat before winter from 1999 to 2001.Showed that different growth regulators could have a great influence on the content of endogenous hormone, such as IAA and (ZR+Z), the ratio of IAA/(ZR+Z), and the tillering capability of Yumai 49. The stem number per hectare treated with PP_ 333 and 6-BA was 10% and 6% higher than ck respectively. The activity of nitrogen reductase was increased and the content of chlorophyll was at the higher level in leaf treated with PP_ 333 and 6-BA,which were of great benefit to form more and vigorous tillers.
