摘要
本文研究了菌核病菌(Sclerotinid Sclerotiorum)侵染油菜叶片的组织病理学。其侵染过程包括:叶片表面侵染垫的形成,寄主表皮的机械直接侵入,侵染菌丝(平均直径16.4μm)的胞间扩展以及分枝菌丝(平均直径7.8μm)的胞间胞内扩展。结果还证实了木质部导管腔内及叶片其它部位菌丝体周围形成草酸盐晶体以及耐、感品系病菌侵染的差异。
Histopathology of infection of rapeseed leaves by Sclerotinia sclerotiorum was studied. The infection process included formation of infection cushions on the surface, mechanical penetration from the host epidermis,development of infection hyphae ( aver.diam.16.4μm ) intercellularly in the epide rmic cells, inter- and intracellular development of ramifying hyphae(aver. diam.7.8μm).The results also showed that oxalate crystals formed in the xylem cells and other areas around hyphae. The difference of infection and development was suggested between tolerant and susceptible varieties ( lines) .
