摘要

不同來源之炭疽病病原菌其産胞能力差異極大，以菌絲塊或分生胞子堆連續移植時，産胞能力極易喪失，可是菌株間之差異頗大。但利用單胞分離法移植時，則産胞能力不會喪失。兩次移植之間隔時間長短亦可影響産胞能力。
當産胞能力隆低時，如以單菌絲尖端稱植，則産胞能力可回復。溫度及培養基均可影響産胞能力。分生胞子發芽時可展現四種不同現象，分別爲(i)先形成發芽寬心而後形成菌絲體、(ii)形成深褐色至黑色之附著器、(iii)二分生胞子二發芽煢間菌絲融合及(iv)産生次生分生胞子。溫度及碳素源可影響分生胞子之發芽。

The sporulation abillity, varied among isolates, was easily lost when cultures were transferred with mycelial or conidial mass, but could be maintained by single-conidium culture method. This ability could be recovered when the culture was subcultured by single hyphal-tip method. Temperature and media, i.e., PDA, carrot agar and oatmeal agar, could affect both sporulation and germination of conidia. Whether or not the sporulation ability was influenced by sequential mycelial mass transfer depended on the isolates used and on the intervals when transferred. When conidia germinated, four phenomena could be observed, (i) emergence of germ tube, (ii) formation of dark-colored appressoria, (iii) anastomosis between two conidia or germ tubes, and (iv) production of secondary conidia.
