The object of experiments reported here was to attempt to resolve conflicting theories of regulation of fruit set in the grape vine.
On the one hand, if fruit set is regulated by supply of organic nutrients, growth of fertilised flowers into fruits could be expected to occur in the absence of leaves, provided that nutrient supply is non-limiting.
On the other hand, if the early stages of fruit development are controlled by specific factors produced by leaves, absence of leaves would prevent further development of fertilised flowers even under conditions of favourable nutrition.
These hypotheses were tested by investigations of fruit set in specially propagated vine cuttings, and by culture of vine inflorescences in vitro.
