摘　　要：红豆杉属的保护与开发研究一直是国际关注热点。密叶红豆杉是西藏重要的药用观赏植物资源。为了满足园林建设和植物药源需求,本试验以密叶红豆杉嫩枝为材料,进行了水培扦插技术研究,以期为批量化生产密叶红豆杉种苗提供技术支持。试验结果表明:密叶红豆杉在水培扦插试验中,有效IBA处理浓度范围是200~800 mg/kg,最适IBA浓度是400 mg/kg,水培65 d^75 d生根率可达90%,平均生根数6.42根,最长根长15.5 cm。The protection and development of Taxus has always been a hot topic in the world.Taxus cuspidata is an important medicinal and ornamental plant resource in Tibet.In order to meet the material needs of landscape and medicinal,this experiment used spray of Taxus cuspidata to study the hydroponics cutting technology for production mass cutting seedlings.The results showed that under the experimental conditions,the effective concentration of IBA was 200~800 mg/kg and the optimum concentration of IBA was 400 mg/kg,while the rooting rate could reach 90%after 65~75 days,with the average root number of 6.42 and the longest root length of 15.5 cm.
