摘要：
The effects of photoperiod and temperature on sprouting were investigated using three cultivars of onion which exhibit different responses to daylength during bulb growth. Two photoperiods (8 h and 14 h) and two constant temperatures (15 °C and 20 °C) were used. Two cultivars showed enhanced sprouting and leaf emergence in short days, and one sprouted poorly in all conditions. In long days, some plants showed growth of new bulbs within the old one, without sprouting. © 1990 Annals of Botany Company.
