| 摘 要： | 通过定点接种、整体透明及石蜡切片测定,接种后24小时,柑桔炭疽病菌可在温州蜜柑幼嫩叶(叶龄为14天)面上大量萌发并产生附着胞。4天后附着胞可进一步形成细长的侵入丝,直接穿透叶片角质层或者经叶背气孔侵入,然后在叶片上表皮或下表皮细胞内形成潜伏、休眠状态的菌丝,直至叶片受伤,这种菌丝才可进一步生长,扩展至叶肉细胞并形成典型的急性炭疽病分生孢子盘。

| Abstract: | Conidia of Colletorichum gloeoprioides germinated and formed appressorium on young leaves (14-day-age) of Citrusunshin Marc. within 24 hours after inoculation. Four days later, infection hyphae occurred from appressorium and pierced the cuticle or stomate.Some liyphae formed in the intracells of the epidermis later, but the hyphae remained quiescent untill the leaves were wounded, leading to formation typical an thranose stroma. |
