| 摘 要： | 在Ｒ５期利用人为每天遮荫８小时,连续遮荫１０天,研究了遮荫对生殖生长期大豆叶片蔗糖合成酶（ＳＳ）,蔗糖磷酸合成酶（ＳＰＳ）,谷氨酸合成酶（ＧＳ）活性及叶片和子粒中的四种内源激素含量的影响,结果表明：遮荫明显增加叶片的三种酶活性,提高子粒中ｉＰＡ,ＧＡ和ＡＢＡ的含量,改变叶片中ＧＡ,ｉＰＡ和ＩＡＡ的积累方式。认为酶活性及内源激素的变化是大豆忍耐遮荫不良环境积极生理反应,有助于减少产量和品质损失。

| Abstract: | Sucrose synthetase
(SS),sucrose phosphate synthetase (SPS),glutamine synthetase(GS) activities in leaf and
endogenous hormone contents in leaf and seed were investigated during soybean reproductive
development after 10 days artificial daily 8 hours shading from R5 stage.The results show
that shading enhances leaf enzyme activities significantly,and increases iPA,GA and ABA
contents in seed and changes GA,iPA and IAA patterns in leaf.It is suggested that the rise
of enzymes and change of hormones is an active physiological responses of soybean to
endure shading stress,which might set off yield loss and quality formation. |
