摘　　要：以泰山红石榴茎段为材料,比较了不同植物生长调节物质配比以及有机添加物(椰汁、香蕉汁、水解乳蛋白)对外植体增殖和生根的影响.结果表明,泰山红石榴的最适增殖培养基为MS+6-BA 1.2 mg.L-1+IBA 0.1mg.L-1,其增殖系数达到3.1;最适生根培养基为1/2 MS+NAA 1.2 mg.L-1,其生根率达到73%;椰汁对石榴外植体的存活率作用显著.The effects of different plant growth juice, banana juice, lactalbumin hgdrolysate） on regulator rations and different organic additives （coconut the multiplication and rooting of explants from Taishanhong Punica granatum L. were compared. The results show that the most suitable multiplication medium were optimum with MS ＋ 6 - BA 1.2 mg·L^-1 ＋ IBA 0.1 mg·L^-1, the multiplication index of shoot was 3.1 ; the best rooting media was optimum with half-strength MS ＋ NAA 1.2 mg·L^-1,the growing rate of root was 73 %. Coconut juice had the most significant effect on the survival ratio of the explant.
