| 摘 要： | 为了评价从日本引进的抗松材线虫病赤松通过无性快繁获得的再生植株在我国的生长状况.本研究对田间试种的抗病赤松6个家系12个无性系共688株再生植株进行跟踪监测.结果表明,抗病赤松0.5年生再生植株试种成活率明显低于2.5年、2年、1.5年及1年生再生植株;不同无性系间抗病赤松再生植株生长状况存在明显差异.其中,1#-A和5#-5无性系再生植株生长较好.菌根化造林试验表明,两种外生菌根菌美味牛肝菌(Be)和黄色须腹菌(R1)对抗病赤松1#-A5代、8代再生植株具有明显促生效果.此研究为今后抗病赤松再生植株造林育种提供了参考依据.

| Abstract: | In order to evaluate the performance of regenerated plantlets of Pinus densiflora resistance to pine wilt disease,research has advanced to the field testing stage.The results showed that 0.5 year-old plantlets survival rate was apparently lower than that of 2.5,2,1.5,1 year-old.There were obvious growth difference among different clones.Mycorrhizal foresting test indicated that ectomycorrhizal fungi Rhizopogen luteous and Boletus edulis facilitated the growth of disease-resistant P.densiflora 1#-A 5 and 8 g... |
