| 摘 要： | 水松为我国特有的珍稀濒危树种。本研究对水松扦插繁殖技术进行了探讨。通过研究母树年龄，采条部位，扦插基质，激素种类、浓度与处理时间，基因型等因素对水松扦插成活率的影响，初步总结出一套水松扦插繁殖技术。以1a生或2a生实生苗顶部枝条为插穗，用2000ppmIBA速蘸处理30s或用100ppmNAA浸泡插穗基部2h，然后扦插在混合基质（草炭：珍珠岩=7：3）中，可以获得较为理想的结果，扦插成活率可达85％以上。试验还发现，不同基因型间生根能力差异显著，表明通过优良单株选择可改良水松的生根特性。

| Abstract: | Glyptostrobus pensilis （Lamb.） K. Koch was an endemic and endangered species in China, therefore, it is of great significance to study on the vegetative propagation techniques of Glyptostrobus pensilis （Lamb.） K. Koch. In this paper we developed techniques on cutting propagation of Glyptostrobus pensilis （Lamb.） K. Koch. The results were as follows. The cuttage propagation techniques of Glyptostrobus pensilis （Lamb.） K. Koch was also explored in this study by testing various factors including ages of the mother tree, cutting position, medium, treatments of hormone types, concentrations and duration. The best way for cottage of Glyptostrobus pensilis was that cuttings came from the top part of 1 or 2-years-old ortets, cuttings soaked in IBA 2000ppm solution for 30s or in NAA 100ppm solution for 2h before inserting in the medium with combination of pearlite：peat=3：7, the rooting ratio of cutting under these treatments above could reach 85%. Significant differences of rooting ratio were found existing among genotypes, indicating that it was effective to select the individual plant with easily rooting ability. |
