仁用杏抗寒性生理指标评价的研究
Evaluation of cold-resistant physiological indices of kernel apricot
摘要
Abstract
The germination rate and physiological indices of three cold-resistant kernel apricots (Youyi>Baiyubian> Long-wangmao) under low temperature stress are studied. And the relationships between these physiological indices and cold resistance of kernel apricots are also analyzed. The results show that the germination rate decreases as the temperature decreases, while the rate of electrolyte leakage, the amounts of soluble sugar and proline and the activity of SOD and POD increase. The results of significant analysis to cold-resistant comparison among various kernel apricots show that the rate of electrolyte leakage in branch, the amounts of soluble sugar and proline in epidermis, the activity of POD in xylem and epiderm can be used to assess the cold resistance of kernel apricot except for the activity of SOD. The result of principal component analysis shows that it is reliable to comprehensively evaluate the cold resistance of kernel apricot by using these physiological indices.关键词
