摘要：

Fruit size is the most important limiting factor in the quality of citrus fruits of the mandarin type. Use of the butylglycol ester of 2,4-dichlorophenoxy propionic acid (2,4-DP) on the mandarin cultivar 'Fortune' immediately after the 'June drop' enhanced fruit growth and improved final fruit size. The increase in size with increasing concentration was linear with a saturation point between 50 and 100 mg l-1. Peel weight and juice content per fruit were increased in absolute, but not relative values. Pulp components were examined and it was shown that 2,4-DP improved fruit size by affecting juice sac development through an enhancement of cell enlargement rather than cell division.
