| Abstract: | The pathogenicity of three strains (F-SD-8, F-BJ-2c-2 and F-HN-2a-1) of Valsa mali var. pyri causing pear canker and one strain (F-SX-A6) of V. mali var. mali causing apple canker in China were comparatively tested by wound inoculation on in vitro twigs of pear, apple and some other woody plants, and in vivo twigs of pear. Significant pathogenicity differentiation was detected in V. mali var. pyri. Generally strains F-SD-8 and F-BJ-2c-2 were highly pathogenic on pear although their culturing characteristics differed greatly. The strain F-SX-A6 was more aggressive on apple than on pear, and the strain F-HN-2a-1 showed significant lower pathogenicity on ten pear cultivars and other seven species of woody plants. Our results confirmed that two variants of V. mali had host preference and were also aggressive to crabapple, apricot, and peach besides apple and pear. Meanwhile, strains F-SD-8 and F-BJ-2c-2 could induce the formation of pycnidia on in vivo twigs of pear, which was not observed on in vivo twigs inoculated with F-HN-2a-1 and F-SX-A6. |
