Abstract

Abstract: 6 parthenocarpic lines of eggplant were used asmaterial to study the effect of temperature and bud stage treatment on parthenocarpic gene expression of eggplant. As the result shows, the tested material is a kind of temperature-sensitive parthenocarpy and express this characteristic under low temperature. The temperature which induces parthenocarpic gene expression range from 7℃ to 15℃ with fruit setting rate between 88.9% to 100%. Artificial emasculation and to get ride of stigmas during bud stage do not affect normal growth of parthenocarpic fruit. Getting ride of stigmas during bud stage can be used as one of the quick and accurate ways to identify the eggplant parthenocarpy.

Key words: Eggplant, Parthenocarpic gene, Temperature, Bud stage treatment
