| Abstract:
In vitro studies of pollen germination were carried out at several time/temperature intervals on detached date palm flowers. Fastest germination and pollen tube elongation in the styles of female flowers occurred at 25 or 28°C. At these temperatures most of the pollen tubes reached the base of the style within 6 h; at 15°C, pollen tubes did not reach the base of the style during the 8-h observation period. | |
