【摘要】 通过苗期亚低温的锻炼,研究水稻品种的诱导抗性.实验结果表明,与抗冷性弱的二九丰相比,抗冷性强的中冷8号通过亚低温锻炼,在叶绿素含量、叶片质膜透性、可溶性糖含量三个指标上表现出更强的抗低温能力.说明不同抗冷性的水稻品种具有不同的诱导抗性.更多还原

【Abstract】 Two cultivars of rice (Zhongleng No 8, cold resistance and Erjiufeng, cold sensitive)were used to study their induced resistance under sub-cold acclimation. In comparison with leaf physiological traits of Erjiufeng, the changes of chlorophyll contents, plasmalemma penetrability and soluble sugar contents showed higher resistance to cold stress in cold acclimated Zhongleng No 8 seedlings. All these changes indicated that the rice cultivars with different cold resistance had different induced resistance.更多还原
