Abstract
檬果炭疽病菌 (Collectotrichum gloeosporioides) 之分生胞子可以無傷痍侵染愛文檬果的幼嫩組織(新葉、幼莖、和花穗)與整個發育期的果實，且只要濕度飽和，受感染部位均可立即顯現病徵。當濕度飽和時，生長發育期與硬期(綠熟果)之愛文檬果果實實在被感染後，表皮上會出現紫紅色小斑點。而幼葉亦可被感染後不立即出現病徵，而至組織老熟後才出黑色、稍凹陷的多角形病斑，引起落葉。以上兩種檬果炭疽病病徵在前人報告中均尚未被描述過。
Conidia of Collectotrichum gloeosporioides were able to attack the fruit in all growing stage, young leaves, stems and flowers of "Irwin" mango without wounding. Moreover, all infected sites developed disease symptoms without going through latent period if the surface was under saturated moisture conditions. Under such conditions, the infected fruit in growing stage and green mature stage showed numerous tiny reddish-purple spots on the affected skins within 3-5 days. Sometimes, leaves infected in the expanding stage did not show disease symptoms until they were mature and aged.
