【摘要】 本试验采用波兰黑穗醋栗(Ribes nigrumL.)优良品种Ceres冬季休眠枝的水培芽为外植体,进行了组织培养研究,建立了其快繁体系,即初代培养基为MS+6-BA 1.0 mg/L;增殖培养基为MS+6-BA 0.5 mg/L+IBA 0.5mg/L;生根培养基为MS+无激素;在此体系中增殖系数可达4.3,生根率100%,最多生根条数可达15条以上。本试验还发现,Ceres品种茎段分枝力较差,但生根能力很强。更多还原

【Abstract】 The buds from water cultured dormant branches of Ribes nigrum L.cv.Ceres were taken as explants in this experiment.The optimum media for initiating,proliferating,and rooting culture were established,i.e.,MS+6-BA 1.0 mg/L,MS+6-BA 0.5 mg/L+IBA 0.5 mg/L and MS+no hormone,respectively.In this system,the highest propagation coefficient was 4.3 and the rooting rate was 100%,more than 15 roots were formed in rooting medium.The result also indicated that Ceres has low branching ability and high rooting ability.更多还原
