摘要
通过对曼地亚红豆杉扦插育苗试验,结果表明:在"全光喷雾"的沙盘内以河沙为扦插基质,插穂以选择幼龄母树1年生半木质化嫩枝为最好,长度以10～12 cm,插穂采用100 mg/L质量浓度的ABT 1号生根粉浸泡1 h后扦插,45 d后形成愈伤组织,90 d后形成愈伤组织率最高达93.3%,第2年4月生根率最高达96.67%。扦插时间在7月中旬为最好。
Though the experiment on cutting propagation of Taxus media, the results showed that using riversand in the sand table with full-light spraying as substrates, one-year-old semi-woody softwood was the best, and its length was 10-12 cm, dipping cuttings in solution of No.1 ABT with a 100 mg/L eoneentration for 1 hour, and form callus after 45 d,the rate of callus was more than 93.3% after 90 d, and rooting percentage of cuttings was over 96.67% on April next year. Middle of July was the best time for cutting.
