本文主要研究了环状倒贴皮处理对富士苹果幼树短枝内可溶性糖、赤霉素、脱落酸及细胞分裂素含量的影响。在整个试验期内,处理植株可溶性糖含量均较对照树显著增加;处理后一个月,与对照树相比,3种激素的变化分别是:赤霉素含量下降;脱落酸含量上升;在细胞分裂素的3个活性组分中,组分B活性增加,而组分A和组分C的活性下降,但细胞分裂素总量变化不大;激素间的平衡变化表现为赤霉素/细胞分裂素组分B和赤霉素/脱落酸的比值明显下降。
In this paper, we studied the effects of ring-shaped veneer on the content of soluble sugar, gibberellin, abscisic acid and cytokinin in young shoots of Fuji apple. During the whole experiment period, the content of soluble sugar in the treated plants increased significantly compared with the control tree. One month after the treatment, compared with the control tree, the changes of the three hormones were: the gibberellin content decreased and the abscisic acid content increased; Among the three active components of mitogen, the activity of component B increased, while the activity of components A and C decreased, but the total amount of cytokinins changed little. The balance between hormones showed gibberellin / cell The ratio of mitogenin B to gibberellin / abscisic acid was significantly decreased.
