| 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... |
