| Research Abstract |
The treatments with girdling above the abscission zone of fruit or defoliation, that inhibited the influx of photosynthetic assimilates into the fruit, promoted fruit softening on the tree. However fruit dropped before they ripened. Pear fruit fully ripened even on the tree by the treatment with abscission inhibitor, NAA, in combination with girdling treatment. Taken together, there might be two tree factors that suppress the ripening of pear fruit on the tree. One is the continuation of influx of photosynthetic assimilates into the fruit. Another is ethylene produced by fruit themselves that promotes fruit drop before fully ripening on the tree.
