摘要: 以湖北省恩施市不同生长年限的叶用银杏(Ginkgo biloba L.)为研究对象,采用单因素方差分析法研究不同生长年限银杏叶黄酮含量的差异,并通过冗余分析(RDA)明确土壤养分对黄酮含量的主要影响因素。结果表明,不同生长年限银杏的槲皮素含量、山奈素含量、异鼠李素含量及总黄酮醇苷含量的变化范围分别为0.21%~0.33%、0.22%~0.33%、0.020%~0.033%、1.15%~1.59%。4年生银杏土壤养分含量最高。不同年限银杏土壤C∶N、C∶P及N∶P的变化范围分别为6.99~8.30、13.24~29.60及1.67~3.57。RDA分析表明,土壤全氮含量及有机质含量是影响黄酮含量的主要因子。银杏生长受到氮素的限制,人工栽培时应适度补充氮肥。

Abstract: Leaf-used Ginkgo biloba L. across different growth ages in Enshi, Hubei Province was used as the research material. One-way analysis of variance was performed to examine variations in leaf flavonoid contents, and redundancy analysis (RDA) was conducted to determine the dominant soil nutrient drivers of flavonoid accumulation. The results showed that the contents of quercetin, kaempferol, isorhamnetin and total flavonol glycosides in Ginkgo biloba leaves across different growth years ranged from 0.21% to 0.33%, 0.22% to 0.33%, 0.020% to 0.033% and 1.15% to 1.59%, respectively. Four-year-old Ginkgo biloba trees exhibited the highest soil nutrient contents. The stoichiometric ratios of C∶N, C∶P, and N∶P in soils under different ages of Ginkgo biloba ranged from 6.99 to 8.30, 13.24 to 29.60, and 1.67 to 3.57, respectively. RDA indicated that soil total nitrogen and organic matter were the dominant factors affecting flavonoid contents. The growth of Ginkgo biloba was limited by nitrogen availability, and appropriate nitrogen fertilizer should be applied in artificial cultivation.

Key words: flavonoid content, leaf-used Ginkgo biloba L., soil nutrients, ecological stoichiometric characteristics
