Although requirements such as those mentioned may be desirable or even essential for an active plant growth regulator, the mechanism of action of the substance in the cell is still unknown. The suggestion that certain of these active molecules may exercise their effects by combination with important thiol enzymes may be most fruitful.

However, the general lack of correlation between endogenous-auxin levels and fruit growth397-409-411 suggests that, for some species at least, auxins are not the sole controlling factors. The conclusion follows that other classes of plant-growth regulators must play a part. 

The exact roles and interactions of hormones in the control of fruit development remain to be determined. The evidence suggests that all classes of plant-growth regulators probably play a part, and that their influence is perhaps effected by changes in their balance. 

N-2-Chloro-4-pyridmyl-N-phenylurea. CPPU [68157-60-8] (47) is a phenylurea plant growth regulator that has been used experimentally to increase fruit size in apples, grapes, kiwifruit, macadamia nuts (Macadamia temifolia)y cotton, small grains, and ornamentals (23).

In recent years, scientists have found that many synthetic growth regulators will develop fruit in plants. The best of these are 4-chlorophenoxyacetic acid and 2-naphthoxyacetic acid. These chemicals are most effective on fruits that have many ovules, such as tomato, squash, egg-plant, and fig. They are usually rather ineffective, however, on peach, cherry, plum, and other stone fruits. Many fruits that can be set by such hormonal compounds also can be set by the gibberellins. In addition, gibberellins can set fruit in some species that do not respond to the other chemicals.
