| 摘 要： | 银杏 (Ginkgo biloba L.)又名白果 ,单属单种 ,是世界上最古老的孑遗植物之一 ,集材用、果用、叶用、园林绿化等于一体 ,我国的人工栽培历史已有 30 0 0余年。银杏专用叶用园的建立于 80年代初起步 ,建园技术模式尚处摸索阶段 ,缺乏系统的研究。截干是培育银杏专用叶用园必不可少的技术措施。本研究对 1年生、2年生和 3年生幼龄银杏实生苗分别以不同留桩高度截干 (或抹顶芽 )处理 ,通过测定当年叶片的叶绿素含量、净光合速率、蒸腾速率、含水率、总黄酮含量、叶产量和总黄酮产量 ,揭示了各处理叶片生理生化特性及单株产量的差异 ,为高效丰…

| Abstract: | In order to cultivate high yield with good quality Ginkgo biloba leaf-producing plantation, coppice management of 1,2,3-year-old Dafuzhi seedling at different stump heights (or top bud pruning) were taken and some physiological and biochemical indexes and yield of Ginkgo biloba leaves were determined on May 15 and September 11. The results showed that the chlorophyll content, net photosynthetic rate, transpiration rate and water contents of all treatments and the total flavonoid concentration of some treatments were higher than those of CK; Leaf yield and total flavonoid yield per plant of some treatments were higher than those of CK at the later stage of the year. |
