| 摘 要： | 研究不同浓度(0、0.2%、0.4%)NaCl盐分胁迫处理对"寒富"、"华红"2个苹果品种1a生嫁接苗叶片中光合作用和光合色素含量的影响。结果表明:盐胁迫改变了苹果叶片光合日变化曲线,使其光合性能整体下降;2个苹果品种的光合色素含量均随着盐浓度的增加而降低。综合分析发现,2个品种在盐胁迫下的光合能力为:"华红""寒富"。

| Abstract: | The effects of salt stress(0,0.2% and 0.4%) on the photosynthesis and photosynthetic pigment of one-year-old seedlings of two cultivars of apple(‘Hanfu’,‘Huahong’) were studied.The results showed that the salt stress resulted in changes of diurnal variation of photosynthetic properties,so that the overall decline in photosynthetic performance;the photosynthetic pigment contents of the two cultivar seedings decreased gradually with the increment of salt concentrations.It was indicated through the comprehensive analysis that photosynthetic capacity of the two cultivar seedings ordered as ‘Huahong’ > ‘Hanfu’. |
