摘要:

旨在明确加拿大一枝黄花在云南省11个不同发生地区的生态适应性。在同质园条件下分别观测其植物性状及差异。试验可以看出,不同入侵地区发生的加拿大一枝黄花,在同质园条件下进一步的生长、繁殖特征差异显著,其中根萌芽性状指数的变异幅度达到了54.23%,茎秆直径、叶宽和叶形指数变异幅度为23.63%~26.31%。在生物量分配比中,花生物量分配占比最高的植株来自文山州丘北县,叶生物量分配占比最高的植株来自昆明西山区,茎秆生物量分配占比最高的植株来自昆明盘龙区,根部生物量分配占比最高的同样来自昆明盘龙区。进一步测定加拿大一枝黄花POD、SOD、CAT、MDA酶活,来自11个不同入侵地区和生境的植株群体表现出显著差异,其中以文山州丘北点和昆明盘龙点的加拿大一枝黄花植株的茎秆、株高和酶活等性状表现较为突出。通过聚类分析发现植物性状中叶表现出一定差异性,但在气候因子的偏相关性分析中发现,原始地的气候因子对加拿大一枝黄花的影响较小。结果表明,加拿大一枝黄花的植物性状基本稳定一致,但不同入侵地区由于环境条件的不同,表型具有一定差异和可塑性。研究结果对明确该加拿大一枝黄花在云南省的生态适应性奠定重要科学基础,同时为预警、监测及防范该入侵植物的扩展提供科学依据。

Abstract:

This study aimed to clarify the ecological adaptability of Solidago canadensis L. in 11 different occurrence areas in Yunnan Province. The plant traits and differences were observed under common garden conditions, respectively. The results showed that the further growth and reproduction characteristics of Solidago canadensis L. occurring in different invasive regions differed significantly under common garden conditions, in which the variation of root sprouting trait index reached 54.23%, and the variation of stem diameter, leaf width and leaf shape indexes ranged from 23.63%-26.31%. Among the biomass allocation ratios, the plant with the highest percentage of flower biomass allocation was from Qiubei County of Wenshan Prefecture, the plant with the highest percentage of leaf biomass allocation was from Xishan District of Kunming, the plant with the highest percentage of culm biomass allocation was from Panlong District of Kunming, and the plant with the highest percentage of root biomass allocation was also from Panlong District of Kunming. In the further determination of the four enzyme activities of POD, SOD, CAT and MDA, the plant populations from 11 different invasive regions and habitats showed significant differences, among which those from Qiubei point and Panlong point were the most prominent. In the cluster analysis, it was found that the leaves in the plant traits showed certain variability, but in the bias correlation analysis of climatic factors, the climatic factors in the original place had less influence on Solidago canadensis L. The results of the study showed that the plant traits of Solidago canadensis L. were basically stable and consistent, but the phenotypes in different invasive areas had some differences and plasticity due to the different environmental conditions. The results of this study lay an important scientific foundation for clarifying the ecological adaptability of the Solidago canadensis L. in Yunnan Province, and provide a scientific basis for early warning, monitoring and preventing the expansion of this invasive plant.
