以红花槭'十月光辉'1年生带顶芽、1年生无顶芽和2年生硬枝为插穗,选用M1(河沙与珍珠岩的体积比为1:1)、M2(河沙与蛭石的体积比为1:1)、M3(珍珠岩与蛭石的体积比为1:1)和M4(河沙、珍珠岩、蛭石的体积比为1:1:1)4种不同的扦插基质,施加不同质量浓度的吲哚丁酸(IBA)和萘乙酸(NAA)进行扦插试验,研究插穗类型、基质种类和外源激素对红花槭扦插生根的影响,并对扦插过程中不定根发育形成过程进行组织学观察.结果表明:M4基质在生根率(69.44％)、平均生根数量(14.31条)和平均根长(5.40 cm)方面均表现最优,为适宜的扦插基质;1年生插穗生根率和平均根数均高于2年生插穗的,平均根长低于2年生插穗的;1年生带顶...

In this study, three cuttings, 1-year-old with terminal bud, 1-year-old without terminal bud and 2-year- old hard branches of Acer rubrum ‘October Glory’, each were applied four types of cutting substrates, named M1 (equal volume of sand and perlite), M2 (equal volume of sand and vermiculite), M3 (equal volume of perlite and vermiculite) and M4 (equal volume of sand and perlite and vermiculite) separately, as well as applied IBA and NAA at different mass concentration ratios. The effects of cutting type, substrate type and exogenous hormones ...
