瓜笄霉学名Choanephora cucurbitarum)是一种植物病原真菌,属于毛霉目英语Mucorales,可引起各种葫芦的果实和花朵腐烂。它也可能会影响秋葵敏豆豇豆,且可能导致睡茄腐败。2017年,Das等人在对印度的茄子凹萼木鳖扁豆豌豆进行研究后,增加了更多关于瓜笄霉的病理指标。瓜笄霉好发于高温高湿的环境,并且会在土壤中盘据。瓜笄霉主要的病征是会感染果实及叶子,其中包含水浸状的病征或坏疽型病斑,且发展快速。当真菌开始产生孢子时,受影响的植株组织会因孢子囊遍布而呈灰褐色及毛茸状。

性状描述

瓜笄霉带有小孢子囊(sporangiola)的孢子囊柄直立、透明且无分枝,顶端膨大长出棒状囊泡,从囊泡中产生二分枝状,亦呈棍棒状的二级囊泡。小型孢子囊为不开裂的,呈椭球状,颜色为棕色至深棕色,具有明显的纵向条纹,尺寸为12-20μm x 6-12μm。孢子囊呈球状,含有多枚孢子,最初的颜色为白色至黄色,成熟时呈浅棕色至深棕色,尺寸为40-160μm。来自孢子囊的孢子囊柄呈椭圆形至宽椭圆形,颜色为棕色至深棕色,具有细小透明极性附属物的不透明条纹,尺寸为16-20 µm x 8-12 µm。[1]
