摘要
以七叶一枝花及其根际土壤为试验材料,测量其株高、茎粗、叶长、叶宽、叶面积等农艺性状,并测定其根际土壤中羟基苯甲酸、香草酸、丁香酸、对香豆酸、阿魏酸等 5 种酚酸类物质的含量,以探究土壤酚酸类物质对七叶一枝花农艺性状的影响.结果表明:不同样地间七叶一枝花农艺性状与土壤酚酸类物质含量之间均存在着显著差异;除叶形指数外,七叶一枝花各农艺性状间呈极显著正相关;5 种酚酸类物质之间存在着不同程度的正相关,但七叶一枝花各农艺性状与土壤酚酸类物质却均呈现不同程度的负相关,且除叶宽和叶柄直径外,均存在显著或极显著负相关.
Abstract
Using Paris polyphylla var.chinensis and its rhizosphere soil as experiment materials,we measured plant height,stem diameter,leaf length,leaf width,leaf area and other agronomic traits,as well as the content of five phenolic acids,including hydroxybenzoic acid,vanillic acid,syringic acid,p-coumaric acid,and ferulic acid in the rhizosphere soil to explore the influence of soil phenolic acids on the agronomic traits of P.polyphylla var.chinensis.The results showed that there were significant differences in the agronomic traits and soil phenolic acid content among different plots of P.polyphylla var.chinensis.Except for leaf shape index,all agronomic traits of P.polyphylla var.chinensis showed a highly significant positive correlation.There were different degrees of positive correlation among the five phenolic acids,but all agronomic traits of P.polyphylla var.chinensis showed different degrees of negative correlation with soil phenolic acids,except for leaf width and petiole diameter,which showed significant or highly significant negative correlation.
