摘  要：
以观赏良种金叶银杏'万年金'为材料,研究了插穗预处理(冷藏、蔗糖、硼酸)和激素(NAA、IBA、NAA+IBA)对金叶银杏硬枝扦插生根的影响,分析不同处理下的不定根长、不定根数、生根率的差异,筛选出较优的预处理和激素处理,为金叶银杏硬枝扦插育苗技术体系建立提供数据支撑.结果表明:(1)基于隶属函数综合评价,排名前三的预处理依次是冷藏 10 d、5.0%蔗糖、0.1%硼酸,其中冷藏 10d处理同步提高了金叶银杏插穗不定根长、不定根数和生根率,5.0%蔗糖处理仅提高了不定根长,0.1%硼酸处理仅提高了不定根数.(2)基于隶属函数综合评价,排名前四的激素处理依次是IBA800、NAA400+IBA400、IBA500、NAA200+IBA200,四个处理均同步显著提高了不定根长、不定根数和生根率;IBA对金叶银杏扦插生根有明显的促进作用,优于NAA和NAA+IBA.(3)基于隶属函数综合评价,IBA500 处理 1h对金叶银杏硬枝扦插生根效果较优.

摘  要：
Using the ornamental variety Ginkgo biloba'Wannianjin'as the material,the effects of cuttings pretreatment(cold storage,sucrose,boric acid)and hormones(NAA,IBA,NAA+IBA)on the rooting of hard branch cuttings of Ginkgo biloba were studied.The differences in indefinite root length,indefinite root number,and rooting rate under different treatments were analyzed,and the optimal pretreatment and hormone treatment were selected to provide data support for the establishment of the hard branch cutting seedling technology system of Ginkgo biloba.The main results are as follows:(1)Based on the comprehensive evaluation of the membership function,the top three pre-treatments ranked in order are refrigerated for 10 days,5.0%sucrose,and 0.1%boric acid.Among them,refrigerated for 10 days synchronously increased the adventitious root length,number,and rooting rate of Ginkgo biloba cuttings.The 5.0%sucrose treatment only increased the adventitious root length,and the 0.1%boric acid treatment only increased the adventitious root number.(2)Based on the comprehensive evaluation of the membership function,the top four hormone treatments ranked in order were IBA800,NAA400+IBA400,IBA500,NAA200+IBA200,all of which significantly improved the length,number,and rooting rate of adventitious roots simultaneously;IBA has a significant promoting effect on the rooting of Ginkgo biloba cuttings,which is superior to NAA and NAA+IBA.(3)Based on the comprehensive evaluation of membership functions,IBA500 treatment for 1 hour has the best rooting effect on hard branch cuttings of Ginkgo biloba.
