1.赤霉素花后处理幼穗能使有核品种玫瑰香葡萄形成大量的无核果粒,提前浆果成熟期半月至三周。处理果穗的浆果一般略小于对照。由于着果率提高,平均穗重并不低于对照,甚至略高于它。 2.赤毒素的效应随濃度增高而增强,以1000ppm的效果較好,500ppm其次,200ppm的效果較差。各处理濃度都不同程度地表現大小粒現象和果粒成熟不一致的現象。 3.加用2,4-D(10 ppm)对赤霉素的良好效应有抑制作用。在浆果失核和提前成熟的效果及平均穗重等方面,混合处理皆不如单独赤霉素处理。单独2,4-D处理有抑制浆果生长、延迟浆果成熟的不良效应,并表現严重的大小粒現象,产量降低很显著。在单独处理及混合处理中,2,4-D有显著促进着果和增强果穗抗病力的初步效应。
Gibberellin treatment of young inflorescences can make the core species of Muscat rosewood grapes to form a large number of non-nuclear fruit, berry maturity in advance half a month to three weeks. The berry treated ears generally slightly smaller than the control. As the fruit rate increased, the average ear weight was not lower than the control, or even slightly higher than it. 2. The effect of redox toxin increased with increasing concentration, with 1000ppm better, 500ppm second, 200ppm less effective. Each treatment concentration to varying degrees, the performance of grain size and grain maturity phenomenon is inconsistent. 3. Addition of 2,4-D (10 ppm) has an inhibitory effect on the good effect of gibberellin. In terms of the loss of nucleation and early maturity of berries and the average panicle weight, the mixed treatment is not as good as that of GA alone. Treatment with 2,4-D alone inhibited the growth of berries and delayed the ripening of berry, and showed serious phenomenon of large and small grains with significant decrease of yield. 2,4-D had a preliminary effect of significantly promoting fruit and enhancing ear disease resistance in single treatment and mixed treatment.
