| Abstract: | The fruit thinning effect of dipterex with kinetics of blossoms and fruit drop was investigated on Red Fuji apple trees. The result showed that dipterex applied 14 days after full blossom at concentration 900 mg.L -1 were satisfied to the requirement of production.The mean fruit weight at harvest and the flowering in the following spring were improved; the range of alternation of the yield was reduced; the fruit yield was reduced; the fruit yield and fruit quality were increased by the spray. |
