- 摘要:
- 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它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它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它4个种源。
- Abstract:
- 5 Castanopsis tibetana provenances of different areas(Jinxiu,Longsheng,Ziyuan,Hezhou,Leye) were selected as experimental materials to study the effect of root length and rooting agent content combination treatment on the hook of C.tibetana Hance seedlings after transplant stages.The results showed that,significant difference of preserving rate existed among different provenances and treatments.Hezhou provenance had the maximum ground diameter annual growth and Ziyuan provenance had the maximum height annual growth in these species.Therefore,Hezhou provenance germplasm might be better than other 4 kinds.
