摘　　要：Castanopsis tibetana of five different provenances （Jinxiu, Longsheng, Ziyuan, Hezhou and Leye） were selected as experimental materials to investigate the effects of treatments combining different root lengths and contents of rooting agent on the growth of C. tibetana after transplanting of seedlings. The results showed that, there were significant differences in the preserving rate of C. tibetana seedlings between different provenances and different treatments. Among the 5 treatments, the seedlings of Hezhou provenance showed the maximum annual increment of ground diameter, and the seedlings of Ziyuan provenance exhibited the maximum annual increment of seedling height. Therefore, the germplasm from Hezhou provenance might be better than those from other provenances.以金秀、龙胜、资源、贺州、乐业5个不同地理种源的钩栗种子为试材,在开展移苗阶段后,研究了不同切根长度和生根剂含量组合的处理方式对钩栗育苗生长的影响。结果表明:不同种源和处理方式钩栗苗木保存率差异明显,5种处理方式中,贺州种源的地径年生长量均比其他4个种源的地径年生长量大,资源种源的苗高年生长量均比其他4个种源苗高年生长量大。因此,贺州钩栗种源种质可能优于其他4个种源。
