摘要
从影响插穗扦插生根的内因和外因两方面,论述了国内对松类扦插技术的研究.提出松类扦插繁殖的思路:加强基础研究,通过子代测定选择一般配合力高的家系或无性系,用其全同胞子代苗扦插扩繁;加强对种内扦插生根率变异性的研究,选择生根力强的无性系、家系或种源;新型植物生长调节剂的研究使用、插穗的采前采后处理、插穗母株的复幼技术等是松类扦插研究的方向;研究易生根基因转移技术和松树基因图谱构建.
Research developments of cutting breeding techniques in China for tree species of Pinus genus were commented from two aspects, i.e. from the interior and exterior factors influencing upon rooting of the cuttings. The strategy for pine cutting breeding was put forward as follows:Fundamental study on genetic testing should be strengthened, seedlings or clones from high GCA(general coupling ability) parents testified by growth of their offsprings should be used for cutting propagation of pine tree species.Researches on rooting rate variation should be undergone to identify the clones, families and provenances with strong rooting capacity and high survival rate.New plant growth regulators and methods for cutting treatment, and for rejuvenation of maternal plants should be studied.Taking advantage of gene transfer techniques, studies on building up the gene map and on transferring the genes related to rooting ability of pine tree species should be stressed.
