Floral initiation under continuous light in Pharbitis nil, a typical short-day plant
Biological Institute, Faculty of Science, Shizuoka University Ôya 836, Sinizuoka 420, Japan
Seedling-cuttings of Pharbitis nil, a typical short-day plant, initiated floral buds under continuous light of 22002400 lux at 2426°C. When cultured under poor-nutritional conditions, the node bearing the first floral bud was as low as the 4th one. A close relation between floral initiation under continuous light and retarded vegetative growth was observed.
