Abstract

This present investigation was conducted in the experimental Farm of Medicinal and Aromatic Research Section, during two successive seasons 1988 and 1989. Four GA3 concentrations 0.100 , 200 and 300 ppm were used in this study. The obtained results showed that GA3 treatments caused a significant increase in height of plants, number of fruits per plant, weight of dry sepales per plant, weight of dry sepales per plot, anthocianin content in dry sepals and total organic acid in se­pals.
