摘　　要：在人工控制条件下,观察了光强对毛脉酸模根中白藜芦醇和白藜芦醇苷的影响.结果表明,较短时期的遮荫使毛脉酸模根中白藜芦醇和白藜芦醇苷含量随着遮荫程度的增加而增加,较长时期的遮荫则使白藜芦醇和白藜芦醇苷含量降低;随遮荫程度和遮荫时间的增加,根中白藜芦醇和白藜芦醇苷含量显著降低.根中白藜芦醇产量在8月份达最大值、白藜芦醇苷产量在9月份达最大值,遮荫降低根中白藜芦醇和白藜芦醇苷的产量.在毛脉酸模生长后期给予短期深度遮荫可以提高白藜芦醇和白藜芦醇苷产量.The study under controlled conditions showed that short-term shading resulted in the increase of resveratrol and polydatin contents in Rumex gmelini root, while long-term shading led to the decrease of them. The increase and decrease were more obvious with increasing shading degree and time. The production of resveratrol reached the maximum in August, while that of polydatin was in September. Shading had a negative effect on the resveratrol and polydatin accumulation in R. gmelini root, but severe shading at the late growth period of R. gmelini increased the production of resveratrol and polydatin.
