| 摘 要： | 在自然条件及人工接种外观无症柑桔叶片表明,柑桔叶片表面存在大量炭疽病菌的附着胞。人工接种幼苗的叶片上虽有大量附着胞存在,但经23个月后仍未见显症发病现象。接种植株上的新叶未见病菌附着胞。叶片组织解剖未发现病菌菌丝,这说明柑桔炭疽病潜伏侵染结构是普遍存在于柑桔叶面的附着胞。

| Abstract: | Microscopical examination of symptomless citrus leaves collected fromnatural orchards or from trees inoculated artificially with Colletotrichumgloeosporioides revealed numerous apprsessoria of the fungus on the citrusleaf surface.However,no disease appearance occurred on the young plantsin 23 months after inoculation.No appressoria were found on the newlyemerging leaves of the inoculated trees,and no mycilia of the funguswere detected in the leaf tissues.It is,thus,considered that the appresso-ria are the latent infection structure of the pathogen on citrus leaves. |
