    摘要:

    为探究草莓花药离体再生体系最适宜培养条件,以草莓品种“枥乙女”花药为试材,研究细胞分裂素TDZ和生长素2,4-D对草莓花药愈伤组织诱导、分化和增殖的影响,筛选不同阶段最适宜草莓花药组织培养激素配比。结果表明,TDZ和2,4-D激素组合可成功培养出草莓花药再生植株,最适宜诱导培养基为MS+2,4-D 0.2 mg/L+TDZ 1.5 mg/L,最适宜分化培养基为MS+2,4-D 0.05 mg/L+TDZ 2.0 mg/L,最适宜增殖阶段培养基为MS+TDZ 0.5 mg/L+2,4-D 0.1 mg/L。

    Abstract:

    In order to explore the most suitable culture conditions of strawberry anther in vitro regeneration system,the effects of cytokine TDZ and auxin 2,4-D on callus induction, differentiation and proliferation of strawberry anther were studied, and the most suitable hormone ratio in different stages of strawberry anther culture were selected with the strawberry cultivar "Tochiotome " anther as test material. The results showed that the combination of TDZ and 2,4-D could successfully culture Strawberry Anther regeneration plants. The most suitable induction medium was MS+2,4-D 0.2 mg/L+TDZ 1.5 mg/L. The most suitable differentiation medium was MS+2,4-D 0.05 mg/L+TDZ 2.0 mg/L. The most suitable proliferation medium was MS+TDZ 0.5 mg/L+2,4-D 0.1 mg/L.
