| 摘要: |
| 通过田间抽样调查和生物统计分析,比较了估计葡萄座果情况的三种不同方法,分析了不同容量的样本之间的差异。初步表明:以每厘米穗轴果粒数反映玫瑰香葡萄的果穗紧密度,较为简便和可靠,样本的容量应不少于30穗。 |

| Abstract: |
| Mature vines of Muscat Hamburg growing in an irrigated vineyard on Tuanhe State farm in the suburb of Beijing were used in 1982. The cluster samples for cluster compactness evaluation were obtained at harvest time from the upper and the middle parts of the vines. 100 labeled clusters consisting of 2 bunches from each of 50 vines were measured and the following date were obtained:(1)number of berries per cluster,(2)number of berries per cm of rachis,(3) number of berries per cm of basal 2 laterals(the wing w... |
