摘要
Abstract
Objective: To study the effect of natural drought stress conditions on Angelica dahurica var. formosana vegetative organs biomass accumulation and allocation in leaf growing scason. To discuss the changing law of Angelica dahurica var. formosana vegetative organs biomass in different drought stress conditions. Methods:Measured Angelica dahurica var. formosana leaf and leafstalk's biomass, all aboveground biomass and the ratio of root biomass,leaf biomass, root/shoot ratio etc. in the growing season under the natural drought stress condition. Results:Slight drought stress condition was good for organs' biomass accumulation, medium and serious drought stress conditions were bad for organs biomass accumulation. Slight and medium drought stress conditions were good for biomass transit to the root in the leaf growing season and serious drought stress condition was not good for that. Conclusion: Suitable drought stress can improve the root biomass ratio in Angelica dahurica var. formosana leaf growing season and get a better yield.关键词
