不同复合配置模式下常夏石竹生理特性研究

为探讨不同复合配置模式下常夏石竹的光合机构功能及其在不同光环境下的生理响应机制,采用大田复合栽培的试验方法,研究了石竹在不同复合配置模式下的生理生态反应。结果表明:石竹叶片的光合、蒸腾、PSⅡ反应中心光合电子传递、实际光能捕获效率、能量耗散能力均因复合配置模式的不同而有所不同,"桂樱×石竹"和"紫叶矮樱×石竹"两种配置模式对石竹叶片光合性能的影响较小,利于石竹生长,而"金枝槐×石竹"配置模式对石竹叶片光合性能的影响较大,不利于石竹生长。

Study on Chlorophyll Fluorescence and Photosynthesis Characteristics of Dianthus plumarius under Different Comprehensive Structure Patterns

In order to discuss the photosynthetic mechanism function and physiological response mechanism under different light environments,physiological ecology response of Dianthus plumarius under different comprehensive structure patterns were studied using compound cultivation method.The results showed that due to the different comprehensive structure patterns,photosynthetic rate,transpiration rate,photosynthetic electron transfer of PSⅡ reaction center,the ability of actual light capture efficiency and thermal dissipation vary changed.The two comprehensive structure patterns of Prunus laurocerasus × Dianthus plumarius and Prunus cistena × Dianthus plumarius had little effect on the photosynthesis of Dianthus plumarius leaves and were beneficial to the growth of Dianthus plumarius.But The comprehensive structure pattern of Sophora jponcia × Dianthus plumarius had great effect on the photosynthesis of Dianthus plumarius leaves and was not beneficial to the growth of Dianthus plumarius.
