VARIETAL RESPONSE OF DIFFERENT EGGPLANT CULTIVARS TO PLANT GROWTH REGULATOR TREATMENTS

J. Nothmann
Growth regulator treatments (2,4-D, 2.5 ppm) were given to eggplant (Solanum melongena L.) cultivars with different growth and flowering characteristics. The plants were grown in the cool season when flower drop is frequent and fruit development is slow and sometimes stops very early.

All cultivars tested reacted favorably to 2,4-D applications, each in its own distinct way. Fruit set and development were much improved, especially in cultivars whose development was more affected by the unfavorable growing conditions of the cool season.

Differential responses in fruit set and in fruit growth were recorded, but fruit growth was improved very much even when the effect on fruit set was restricted. Only on 2,4-D-treated plants did all or most of the fruits reach adequate size.
