摘要

Effect of CCC on growth and fruiting 'Doyenne du Comice' trees in the year of application and to the following year after spraying was investigated. A single spraying with CCC strongly inhibited growth of shoots and favoured profuse setting of flower buds especially at the apex and in the apical part of long shoots. As a result of this in the following year the number of terminals was greatly redused and so was the sum of the terminal lengths. On the other hand the percentage of very long shoots was incresed. In the third season after spraying the trees exhibited very vigorous growth.
