Parthenocarpy in Tomato

Abstract

Tomato is a self-pollinated crop and normally produces seeded fruits when fertilization takes place. The current cultivars set fruits within a narrow range of temperatures of 15° to 21°C (night) and 30° to 35°C (day). Beyond these range of temperatures generally there is no fruit set because of the lack of production of sufficient amounts of fertile pollen and difficulties in pollination and fertilization. A low degree of flower fertilization and fruit set is observed in tomato plants grown in glasshouses with low light intensity and short days.
