The long-term effects of chlormequat on 'Doyenne du Comice' pear

Acta Horticulturae (34): 199-202

The long-term effects of chlormequat on 'Doyenne du Comice' pear

A single spray of chlormequat at 5000 or 10 000 p.p.m. strongly inhibited growth and induced abundant flower initiation at the apices of the long shoots. As a result, total shoot growth and the number of terminals were reduced in the following year, though the percentage of very long shoots was increased. In the second season after spraying, the trees made very vigorous growth but failed to initiate flowers.
