摘要
以山茶21个种质为材料,通过野外田间调查和室内人工接种试验,研究了其对炭疽病和软腐病的抗性。结果表明,21个山茶种质的炭疽病发病率高于软腐病,发病时间早于软腐病,扩散速度快于软腐病;研究提出了炭疽病防治最佳药剂处理组合。
In order to evaluate resistance of 21 Camellia germplasms to Colletotrichum gloeosporioides and Myrothecium camelliae, the field investigation and artificial inoculation were carded out in the experimental sites. The results show that disease incidence of C. gloeosporioides was higher than that of M.camelliae, the onset time of C. gloeosporioides was a little earlier than that of M.camelliae, and the diffusion velocity of the former was faster than the latter. The anthrax prevention optimum combination of pharmaceutical treatment was put forward to prevent C.gloeosporioides of 21 Camellia germplasms.
