CLIMATIC EFFECTS IN CHINESE CABBAGE FOR EARLY PRODUCTION

In order to optimize the method of raising transplants of early Chinese cabbage some climatic after-effects of the young plant treatment were studied.

The suspectibility to bolting after transplanting was determined by photoperiod and temperature during the raising period.
Short day and increasing temperature delayed bolting.
The temperature during day and night showed similar effect on bolting.
The use of older transplants redused bolting and flowering.

The results indicates the possibilities of energy saving by lowering temperatures during the night in combination with higher day temperatures or with short day treatment during the raising period.
