摘　　要：以旋覆花为试材,采用人工增水处理方法,分析了旋覆花生长特征对增水处理的响应。结果表明:增水处理显著增加旋覆花株高、生物量累积、花朵数目,但减小了旋覆花花朵大小;同时增水处理显著影响旋覆花开花时间;旋覆花花朵数目与生物量存在显著关系。Inula japonica Thunb.was taken as material,the effects of water addition on growth characteristic of I.japonica was studied.The results showed that water addition treatment significantly increased plant height,biomass and flower number,but significantly decreased flower size.Water addition treatment affected flowering time.Furthermore,there was a significant relationship between flower number and biomass of I.japonica.
