不同生态因子与有效成分含量的相关性尚无系统研究报道,花,淫羊藿的叶性状。在这项研究中,对不同地区的21种毛竹进行了调查,两种有效成分淫羊藿苷(I)和淫羊藿苷C(C)的含量,并测定了6个叶片性状和12个花性状。连续五年对11个生态因子与不同地区上述性状的相关性进行了初步探讨。结果表明,毛竹两种有效成分(I+C)的总含量与生态因子之间无显著相关性。纬度和温度(包括年平均温度,年平均最低气温,和各土层土壤温度)与两种有效成分含量之比(C/I)(P<0.01)呈极显著正相关和负相关,分别。生态因子与花卉性状之间存在显著的相关性,和每个土层的年平均土壤温度,年平均气温,多年来,年平均最低温度与大多数花卉性状呈极显著相关(P&lt;0.01)。然而,生态因子与叶片性状之间的相关性较弱。仅在几年内,每个土壤层的年平均土壤温度和年平均湿度(P&lt;0.01)与养分叶的宽度呈显着正相关。因此,结论是,毛竹有效成分的总含量是由遗传学决定的,受生态因素影响较小。年平均气温,年平均最低气温,和土壤温度是对花卉性状影响最显著的生态因子,在不同地区表现出显著差异,在叶片性状中没有发现类似的结果。总的来说,本研究系统地进行了生态因子与有效成分的相关性分析,以及花和叶的特征,为质量改进提供指导,介绍,和毛竹的驯化。
No systematic research has been reported on the correlation between different ecological factors and the effective component content,
flower, and leaf traits of Epimedium pubescens. In this study, 21 kinds of E. pubescens in different regions were investigated, and the content of two effective components of icariin(I) and Epimedin C(C), as well as six leaf traits and 12
flower traits were determined. The correlation between 11 ecological factors and the above traits in different regions for five consecutive years was explored. The results showed that no significant correlation was observed between the ecological factors and the total content of two effective components(I+C) of E. pubescens. Latitude and temperature(including annual average temperature, annual average minimum temperature, and soil temperature of each soil layer) were significantly positively and negatively correlated with the ratio of the content of the two effective components(C/I)(P<0.01), respectively. There was a significant correlation between ecological factors and
flower traits, and the annual average soil temperature of each soil layer, annual average temperature, and annual average minimum temperature were significantly correlated with most
flower traits in multiple years(P<0.01). However, a weak correlation between ecological factors and leaf traits was detected. A significant positive correlation of the annual average soil temperature of each soil layer and annual average humidity(P<0.01) with the width of nutrient leaf in only a few years was detected. Therefore, it was concluded that the total content of effective components of E. pubescens was determined by genetics, with a slight influence of ecological factors. The annual average temperature, annual average minimum temperature, and soil temperature of each soil layer were the ecological factors that had the most significant impact on
flower traits, which showed significant differences in different regions, and similar results were not found in leaf traits. Overall, this study systematically conducted a correlation analysis between ecological factors and the effective components, as well as flower and leaf traits, providing guidance for the quality improvement, introduction, and domestication of E. pubescens.
