杉木扦插,如用萌条作插穗可以得到正常植株,但用侧枝扦插,虽能长出苗木,而多呈匍匐状,无甚应用价值。因此,从1979年8月开始,我们开展了用组织培养法快速繁殖杉木优树的研究,现将取得的初步结果报导如下: 一、材料与方法 供试材料为本省高淳1号杉木优树(14年生)和宜兴、句容林场杉木优树(20年余生)。外植体为顶芽、嫩茎和组织培养诱导出的腋芽。所用基本培养基为 Chinese fir cuttings, such as sprouts cuttings can be used to get normal plants, but the cuttings with lateral branches, although the seedlings can grow, but mostly prostrate, of little value. Therefore, starting from August 1979, we carried out the research on the rapid propagation of Cunninghamia lanceolata Tissue Culture by tissue culture method. The preliminary results obtained are reported as follows: I. Materials and methods The tested materials are Gaochun 1 Cunninghamia lanceolata 14-year-old) and Yixing, Jurong fir tree trees (20 years remaining). The explants are buds, tender stems and axillary buds induced by tissue culture. The basic medium used is
