【摘要】 系统研究了外植体类型,植物激素,光温环境因子,抗氧化剂(PVP)和吸附剂(VC)对建立沾化冬枣离体再生苗褐化的影响。结果表明:水培芽和低浓度的细胞分裂素可减轻离体再生苗褐化,培养初期,低温、暗处理、缩短转接培养基周期2、.0～5.0 g/L的PVP和一定浓度的VC可有效抑制植株体褐化。更多还原

【Abstract】 The explants type,plant hormone,environmental factor of light and temperature,antioxidants(PVP) and the absorbent(vitamin C) which results in the browning of Winter Ziziphus jujube var-Zhanhua were studied.The results showed that the bud under water-culture and low concentration of cytokine can reduce browning.In early stage,the low temperature,dark,short culturing cycle,2.0～5.0 g/L PVP and certain concentration of VC can effectively inhibit browning.更多还原
