| 摘 要： | 通过调查测定巨峰、红富士、红瑞宝、玫瑰香、白香蕉5个品种葡萄的单株产量及与其相关的单株结果母枝数,以及结果母枝的剪留芽数、萌芽率、结果枝率、结果系数、果粒重、每穗果粒数、果穗重8个性状,应用逐个选入显著自变数的回归方法,得到包括单株结果母枝数、果粒重和每穗果粒数在内的最优多元线性回归方程。再对入选的3个主要性状进行通径分析,明确了提高葡萄单株产量,首先要具有一定的结果母枝数,这是形成枝叶和果穗的基础;其次要达到一定的果粒数;再次为增大果粒重。

| Abstract: | The optimally linear equation of multiple regression on the yield formation in Jufeng. Hongfushi, Hongruibao, Muscat Hamburg and Baixiangjiao of 5 grape cultivars (Vitis), involving fruit mother branch number per vine, berry weight and berry number per cluster, was acquired by regression method of selecting significant self-variable one by one, after investigating and measuring yield per vine and 8 relative characters of fruit mother branch number per plant, bud number and percentage of bud bursting per fruit mother branch pruned, percentage of fruit branch, fruit coefficient, berry weight, berry number per cluster and cluster weight respectively. Then, it was definit for yield formation that, by path analysis on cach main character selected, the first, there must be certain number of fruit mother branch forming shoots, leaves and clusters; the second the certain berry number, then followed by the berry weight. Controlling properly the berry number per cluster, However, is of benefit not only to increase the cluster weight and to promote the berry quality, but also to reduce the consumption of nutrient substance in the vine body and to inercase the number of highgrade fruit mother branch the next year. |
