The number of flowers, however, ranging from 13.2 at 27.C and ND + 10HID given at >3L stages to 18.3 at 15.C and ND, were not significantly different from other treatments when the number of flowers fell within this range. Plant height was significantly tall when plants were grown at 19.C under ND at>3L stage (13.6 cm) as compared to plants grown at 27.C under ND at >3L stage (11.2 cm). Plant height of all other treatments regard-less of temperature, irradiance level, and developmental stage of leaves was not significantly affected.
