| 摘 要： | 通过查阅大量资料文献，对影响松类针叶树无性系林业发展的障碍因素如不同个体的生根性差异、年龄效应和位置效应、插穗规格、扦插环境等进行了探讨．认为选择易生根群体或个体、克服年龄效应和位置效应、利用外源激素调节、选择合适的季节、有效控制外部环境是提高松类树种无性繁殖系数的有效途径． |
| 关 键 词： | 松类针叶树 无性繁殖 年龄效应 位置效应 遗传增益 外源激素 |

| Abstract: | According to literature review,the paper explores the barrier factors which affect clone forest development in terms of coniferous trees such as Pinus spp.It concerns that easily rooting group or individual,suitable season,effective control of outside environment are some effective ways to improve clone coefficient. |
