在适宜的栽培条件下,植物生长强度与抗热性的相互制约乃是产量上的一个中心问题。对于越冬植物来说,强的越冬性和高的生长活性不可能同时兼有。人们已经注意到生长细胞耐热性的降低,并指出适应抗性的提高与蛋白质合成体系活性的关系。但是,现有的少数试验资料及其某些矛盾观点,使得人们不可能对处于不同生长时期的喜温植物细胞抗寒性做
Under appropriate cultivation conditions, the mutual restraint of plant growth and heat tolerance is a central issue in yield. For overwintering plants, strong overwintering and high growth activity can not be combined at the same time. People have noticed the decrease of heat-tolerance of growing cells and pointed out the relationship between the improvement of adaptive resistance and the activity of protein synthesis system. However, the existing minority experimental data and some contradictory opinions make it impossible for people to do cold-tolerance of hi-temperature plant cells at different growth stages
