对巨峰葡萄副梢结果母枝的结实特点、产量因素及其与节位及树龄的关系进行了研究,并以主梢结果母枝为对照进行了比较分析。发现副梢母枝抽生的结果枝数、花穗数、花穗长度、每花穗的小花数均显著或极显著高于主梢母枝,并且与节位呈极显著或显著的直线相关或曲线相关关系。副梢结果母枝以靠近基部和中部的节位芽眼质量较好,第7节开始质量有下降的趋势,主梢母枝近基都节位也易形成花芽,但花芽质量以中上部者较佳。试验还表明,以每一芽眼生产的浆果果粒数作为产量因素,副梢是主稍母枝的2.3倍,差异极显著。3年生幼龄巨峰与6年生巨峰比较,副梢母枝的结实能力无显著差异。
The fruiting characteristics of main branches of Kyoho grapes, the yield factors and their relationship with the node and tree age were studied. The main shoots of the main fruits were compared and analyzed. It was found that the number of branches, the number of spikes, the length of flower spikes and the number of flowers per spike were significantly or very significantly higher than those of main shoots, and were significantly or significantly related to node Or curve correlation. The shoots of the secondary shoots showed good quality in the shoots near the base and the middle of the shoots. The quality of the shoots tended to decrease from the beginning of the seventh section. The buds of the shoots of the shoots of the main shoots also easily formed flower buds. However, good. The experiment also showed that the number of berry fruit produced per bud was the factor of yield, and the secondary shoots were 2.3 times of that of the main shoots, the difference was extremely significant. Compared with the 6-year-old Jufeng, the 3-year-old juvenile peak had no significant difference in the fruiting ability of the parent shoots.
