| 摘 要： | 北美红杉(Sequoiasempervirens(Larnb )Endl )简称红杉。又名世界爷、美国红杉树,为杉科(Taxo diaceae)单种属植物,世界上稀有的孑遗树种,也是世界著名的速生珍贵大径级用材树种和巨大锯木工业的主要原料1,2]。国外对北美红杉的组培研究较多,并进行了老树复幼工作3,4]。由于目前红杉在国内尚属引种阶段,种源极少,且种子繁殖后代分化较为严重,2000年4月云南省林科院从法国引进了63个优良无性系,为使这些无性系得以扩繁,结合前期已引种的红杉开展了北美红杉组织培养研究,以便为批量生产优良无性系提供理论基础和技术支撑。1 材料与方法1 …

| Abstract: | In order to propagate and cultivate Sequioa sempervirena,taking 63 clones introduced from France as samples,the study on techniques and measures of tissue culture of Sequioa sempervirens was carried out from the aspects of sample preparing,explant differentiation inducting,bud propagating,and root generating.The results showed that the optimum medium for inducing bud differentiation was MS+6-BA1.5 mg·L-1+KT2.0 mg·L-1,root medium was 1/2MS+IBA1.0 mg·L-1+NAA2.0 mg·L-1. |
