Abstract

The effect of different growing methods on bolting of early Chinese cabbage was studied. Both plant age and the duration of low-temperature treatment had a significant effect on bolting. When the appearance of the flower buds was delayed as much as 80 days from sowing, the heads were of good quality.

Increased plant age (1–3 weeks) at the start of cold treatment delayed bolting. Premature bolting was reduced by prolonging the raising period at a temperature above 18°C. Increasing the duration of cooling at 12°C from 1 to 3 weeks hastened bolting in the heat-sensitive ‘Nagaoka 50’. A large difference in bolting responses was found between heat-sensitive (‘Nagaoka 50’) and heat-tolerant (‘Saladeer’ and ‘Nagaoka Tropicana’) cultivars.

    These studies and our results suggest that cis-regulatory evolution at BrVIN3.1 and BrFLC1 loci are an important source of bolting-time variation and may be a more efficient and plastic mechanism of selection to climatic selective gradients compared with protein coding sequence changes due to limited pleiotropy and incomplete dominance. Traditional Chinese cabbage needs a vernalizing stimulus and subsequent long-day conditions for bolting (Pressman and Negbi, 1981), although photoperiod appears to be less crucial than vernalization (Guttormsen and Moe, 1985). In Arabidopsis, the cold and photoperiod signaling have been reported to be linked in flowering-time regulation.
