摘要: 以白木香[Aquilaria sinensis( Lour .)Gilg.]的叶片、茎、芽和根为试验材料,采用DPS软件进行正交试验设计,通过施加不同种类与浓度的植物生长调节剂(6-BA、2,4-D、TDZ、NAA、KT),探究生长调节剂组合及其浓度对白木香愈伤组织诱导、分化及生根的影响。 结果表明,诱导白木香愈伤组织的最适外植体为叶片,最高诱导率为100%,叶片愈伤诱导的最佳培养基为WPM+6-BA 1.5 mg/L+2,4-D 0.5 mg/L+NAA 0.8 mg/L+ KT 0.2 mg/L+TDZ 1.0 mg/L。白木香不定芽诱导的最佳培养基为WPM+6-BA 0.5 mg/L+NAA 0.2 mg/L+ 蔗糖20 g/L+琼脂粉6 g/L。芽、茎的愈伤组织可分化为不定芽,不定芽诱导的最佳培养基为WPM+6-BA 0.5 mg/L+NAA 0.2 mg/L+蔗糖20 g/L+琼脂粉6 g/L,诱芽率为72.22%,不定芽数为5.68个/块。诱导生根的最佳培养基为1/2 MS+NAA 1.0 mg/L+蔗糖20 g/L+琼脂粉6 g/L,生根率为46.67%。

Abstract: Using the leaf,stem,bud, and root of Aquilaria sinensis(Lour.) Gilg. as experimental materials, an orthogonal experimental design was employed via DPS software. By applying different types and concentrations of plant growth regulators (6-BA, 2,4-D, TDZ, NAA, KT), the effects of growth regulators combinations and their concentrations on callus induction, differentiation, and rooting of Aquilaria sinensis were investigated. The results showed that the optimal explant for inducing Aquilaria sinensiscalluswas theleaf, with the highest induction rate of 100%. The optimal medium for leafcallus induction was WPM + 6-BA 1.5 mg/L + 2,4-D 0.5 mg/L + NAA 0.8 mg/L + KT 0.2 mg/L + TDZ 1.0 mg/L. The optimal medium for adventitious bud induction ofAquilaria sinensiswas WPM + 6-BA 0.5 mg/L + NAA 0.2 mg/L + sucrose 20 g/L + agar 6 g/L. The callus from buds and stems could differentiate into adventitious buds. The optimal medium for adventitious bud induction was WPM + 6-BA 0.5 mg/L + NAA 0.2 mg/L + sucrose 20 g/L + agar 6 g/L, resulting in a bud induction rate of 72.22% and an average of 5.68 adventitious buds per explant. The optimal medium for root induction was 1/2 MS + NAA 1.0 mg/L + sucrose 20 g/L + agar 6 g/L, achieving a rooting rate of 46.67%.

Key words: Aquilaria sinensis(Lour.) Gilg., explants, callus induction, plant regeneration, orthogonal test
