山东林下和大田种植西洋参生长与次生代谢产物积累的差异研究
Differences in growth and secondary metabolite accumulation of Panax quinquefolius between understory and field planting in Shandong,China
摘要
Abstract
In order to compare the differences in growth and secondary metabolite accumulation of Panax quinquefolius between understory and field planting,growth indexes,photosynthetic characteristics,soil enzyme activities,secondary metabolite contents,and antioxidant activities of P.quinquefolius under different planting modes were examined and compared,and One-way analysis of variance(ANOVA)and correlation analyses were carried out by using the software SPSS 25.0 and GraphPad Prism 9.5.The Origin 2021 software was used for plotting.The results showed that compared with those under field planting,the plant height,leaf length,leaf width,photosynthetic rate,and chlorophyll content of P.quinquefolius under understory planting were significantly reduced,and arbuscular mycorrhizal fungi(AMF)infestation rate and infestation intensity,ginsenoside content,and antioxidant activity were significantly increased.The activities of inter-root soil urease,sucrase,and catalase increased,while the activities of non-inter-root soil urease and alkaline phosphatase increased.Correlation analyses showed that the plant height and leaf length of P.quinquefolius plant were significantly positively correlated with net photosynthetic rate,transpiration rate,chlorophyll content,and electron transfer rate(P<0.05),while ginsenoside content was significantly negatively correlated with net photosynthetic rate,chlorophyll content,and electron transfer rate(P<0.05)and significantly positively correlated with AMF infestation rate and infestation intensity(P<0.05).In addition,ginsenoside content was significantly positively correlated with the activities of inter-root soil sucrase,urease,and catalase(P<0.05).This study provides basic data for revealing the mechanism of secondary metabolite accumulation in P.quinquefolius under understory planting and for exploring and practicing the ecological mode of P.quinquefolius under understory planting.关键词
