在杨树插条上,利用烧伤伤口接种杨树烂皮病菌(cytoepora chrysosperma(pers.)Fr.),接种后的插条很快出现烂皮病。插条含水率为33%时病的发展速度此100%时快,60%时中等。不同品种裼树烂皮病的发展速度是有差别的。接种伤口周围的环境条件是造成这种差别的原因。因此乃对伤口的组织状况进行研
On poplar cuttings, the infected cuttings were inoculated with cytoepora chrysosperma (pers.) Fr. Cuttings moisture content of 33% of the rate of disease development when the 100% fast, 60% medium. There are differences in the rate of development of different varieties of shrubs. The environmental conditions around the inoculation wound are the reason for this difference. So is the organization of the wound research
