Research on the Multiplication and Growth of Clustered Buds of Pinus armandii Franch

XU Xin-yu et al(College of Resources,Southwest Forestry University,Kunming,Yunnan 650224)  
[Objective] The purpose was to supply references for breeding tissue-cultured seedlings of Pinus armandii Franch in large scale.[Method] The mature embryos of P.armandii were used as materials for inducing clustered buds and researching the influence of factors on the multiplication of clustered buds,such as medium,hormone levels,active carbon(AC) and picking off apical bud.[Result] DCR was the optimum medium for the multiplication and growth of clustered buds of P.Armandii;the multiplication of buds needed higher concn.of 6-BA and the addition of NAA went against the multiplication of clustered buds.AC showed obvious promoting effect on the elongation of differentiated buds and its optimum addition amount was 2.0 mg/L.The multiplication and growth of the clustered buds in the medium of DCR+4 mg/L 6-BA+0.01 mg/L NAA+30 g/L sucrose were better.Picking off apical buds could promote the multiplication of clustered buds,but their growth coefficient was smaller.[Conclusion] The adventitious buds of P.armandii were induced successfully and its rapid multiplication was realized in this research.
