松针褐斑病是我国南方湿地松人工林中普遍存在的一种病害,其病原菌为 Lecano-sticia acicola,是 Scirrhia acicola 的无性阶段。发生该病害的林分,林木生长发育均受到较大程度的影响,局部地区可能出现毁灭性的后果。抗病性选择是病害防治的一种有效手段,加强对抗松针褐斑病家系的选育,对我国南方引种成功的重要造林树种湿地松的推广和发展有着重大的意义。因此,
Pine needle brown spot is a common disease of Pinus elliottii plantation in southern China. Its pathogen is Lecano-sticia acicola, which is asexual stage of Scirrhia acicola. The occurrence of the disease stand, tree growth and development are subject to a greater degree of impact, some areas may have devastating consequences. Disease resistance selection is an effective means of disease prevention and control to strengthen the fight against pine needles brown-spot pedigree breeding, the success of the introduction of southern China an important afforestation species of Pinus elliottii promotion and development of great significance. therefore,
