Abstract

The present study was conducted through the two growing seasons of 2017 and 2018 to disclose the impact of foliar application with different concentrations of stigmasterol (0, 25, 50, 75 and 100 ppm) on vegetative growth characters, yield of fresh herb/plant, anatomical structures of vegetative organs (main stem and leaves) and percentage and constituents of aromatic oil of basil plant. The obtained results indicated that stigmasterol application had a enhancing effect on growth and productivity as well as on the percentage and composition of volatile oil of basil plant and the maximum promotion was detected at 100 ppm stigmasterol. Such treatment induced favorable changes in the anatomical structures of vegetative organs.
