Environmental factors controlling the time of flower opening in pharbitis nil



Environmental factors controlling the time of flower opening in pharbitis nil



Plant & Cell Physiology 20(8): 1659-1666



P. nil, strain Violet, subjected to various photoperiods (24 h cycle at 24.degree. C) bloomed about 10 h after light-off when the light period was 10 h or longer, and about 20 h after light-on when the light period was shorter. The higher the temperature (20-30.degree. C) during the dark period, the later the time of flower-opening, with the temperature during the last half of the dark period having a stronger effect than that during the 1st half. In continuous dark or light, flower buds of Pharbitis opened about every 24 h at all temperatures tested between 20 and 28.degree. C, which suggests the participation of a circadian rhythm in determining the time of flower-opening. A light pulse given 6-12 or 28-36 h after the onset of the dark period greatly advanced the phase of this rhythm (8-10 h). Phase delay of this rhythm could not be obtained by light pulses given at any time.
