| 摘 要： | 以不同浓度的水杨酸(SA)+CaCl2水溶液对营养生长到花芽分化期的菊花"兼六香菊"品种进行全株喷雾处理,测定了整个蕾期叶片中的一些生理生化变化.结果表明,除呼吸速率降低以外,不同浓度的SA+CaCl2处理均能提高菊花蕾期叶片中叶绿素、可溶性蛋白、可溶性糖含量以及光合速率、硝酸还原酶(NR)和超氧化物歧化酶(SOD)活力.各处理组的花期与对照相比均有不同程度的提前,其中以SA15 mg.L-1+CaCl2160 mg.L-1处理效果较佳.

| Abstract: | The chrysanthemum "jian liu xiang ju" are sprayed from vegetative growth to flower bud differentiation with different concentrations of salicylic acid and calcium chloride solution,physiological and biochemical indexes in the leaves of greed bud stage are determined.The result shows that: compared with the controls,except for respiratory rate decreased,different concentrations SA + CaCl2 can enhance the content of chlorophyll,soluble protein and soluble sugar,photosynthetic rate,and the activity of NR and SOD,the florescence is lengthened to some extent,and the best treatment effect is SA15 mg·L-1+CaCl2160 mg·L-1. |
