【摘要】 对影响中国李离体繁殖的有关因素进行了研究．结果表明，中国李增殖和生长适宜的ＢＡ和ＩＢＡ 浓度分别为１．０ ｍｇ／Ｌ和０．０５ ～０．１ ｍｇ／Ｌ，生根适宜的ＩＢＡ浓度为０．４ ｍｇ／Ｌ；培养基中加入ＧＡ３ 和降低ＮＨ４ＮＯ３ 浓度有利于加长生长；用山梨醇作碳源时芽的增殖倍数高于蔗糖，而生根率低；２ 个品种中，“晚红李”的增殖和生长优于“美丽李”，而生根率无明显差异．更多还原

【Abstract】 Some factors influencing the efficiency of micro in vitro propagation of Chinese plum ( Prunus salicina Lindl.)were studied.The results showed that the optimum concentrations of benzyladenine(BA) and indole 3 acid butyric(IBA) for shoot proliferation and growth were 1.0?mg/L and 0.05～0.1 mg/L respectively.IBA at 0.4?mg/L was most favourable for rooting.Adding gibberellic acid(GA 3) and reducing the NH 4NO 3 concentration to 1/2?MS medium promoted shoot elongation compared with sucrose.Sorbitol promoted proliferation,but decreased rooting capacity.‘Wanhongli’ showed higher proliferation rate and growth than ‘Meilili’,but there was no significant difference in rooting capacity.更多还原
