TOMATO FRUIT GROWTH IN RELATION TO METHODS OF IMPROVING FRUIT-SETTING
Auxin, gibberellin and an electric vibrator were applied to the flowers of tomato plants (Lycopersicon esculentum Mill., cv. Montecarlo) grown in a polyethylene greenhouse without heating in spring, with minimum temperatures ranging from 9.0 to 15.4° C. The vibrator produced high number of normal seeds per fruit, while auxin treated plants had mainly big fruits with aborted seeds, and the control plants had small fruits some of them seedless. Every growth curve of fruit diameter had a sigmoid form, with big fruits growing faster than small ones. The higher the number of seeds the faster was the growth. Growth rate rather than the final diameter was influenced by number of seeds. For the same growth rate the auxin treated fruits were bigger than those treated with the vibrator.
