Т·Д·李森科院士在自己的著作中指出,在棉花发育中,温度是外界环境的最重要因素。例如,种子出茅需要的最低温度为10℃,现蕾需20℃,开花需12℃。我们的研究表明,在棉花对温度的要求与氧化还原酶的温度系数之间存在着密切的联系。棉花在蕾期对温度的要求最高。在这一阶段,它的酶系统可以在高温下活动。当温度为25℃时,棉花幼苗于播种后第5天出土,当温变为15℃时,于第10天出土。出芽势减低 In his book, Academician T. Tyson pointed out that in the development of cotton, temperature is the most important factor in the external environment. For example, the lowest temperature required for seeds to bloom is 10 ° C, budding requires 20 ° C and flowering requires 12 ° C. Our research shows that there is a close relationship between the temperature requirement of cotton and the temperature coefficient of oxidoreductase. Cotton buds in the highest temperature requirements. At this stage, its enzyme system can be activated at high temperatures. When the temperature was 25 ℃, the cotton seedlings were excavated on the 5th day after sowing. When the temperature was changed to 15 ℃, the seedlings were excavated on the 10th day. Decreasing budding potential
