摘要
对广西4个产地翅荚木1年生苗木叶片的叶绿素和叶绿素荧光动力参数日变化进行测定。结果表明,4个产地间叶片的叶绿素含量存在显著性差异,靖西产地叶片的叶绿素a、叶绿素b和叶绿素总量均是最高的;4个产地间的叶绿素荧光动力参数日变化差异达到显著水平,忻城和平果产地比天等和靖西产地具有更高的光能利用效率、电子传递活性和自我保护能力,表现出对南宁气候条件较好的适应性;翅荚木叶绿素含量与叶绿素荧光动力参数之间显著相关,但是由于受众多因素影响,不能简单地概括为正相关性或负相关性。
In this paper,the diumal variation of leaf chlorophyll content and chlorophyll fluorescence parameters of one-years-old Zenia insignis seedlings from four different places of origin in Guangxi were analyzed.The results showed that there were significant differences on leaf chlorophyll contents among four different places of origin.The content of chlorophyll a and chlorophyll b and total content of chlorophyll of Z.insignis seedlings leaves from Jingxi was the highest.Significant differences on the diurnal change of chlorophyll fluorescence parameters were found among four different places of origin.Z.insignis seedlings from Xincheng and Pingguo exhibited higher radiation utilization efficiency,electron transport activity and self-protection ability than those of the seedlings from Tiandeng and Jingxi,which adapted well to the climate of Nanning.There was significant correlation between leaf chlorophyll content and chlorophyll fluorescence parameters.Due to many influencing factors the correlation orientation （plus or minus） could not be simply confirmed.
