Abstract
以挑單一孢子的方式可將甜瓜白粉病純化培養於甜瓜葉圓片（直徑1.5 cm）上，於20-24℃培養14-16天可獲得大量可吹落之分生孢子(4.5×10^4-6.8×10^4 conidia/leaf disc)，發芽率24.8-42.3%，而16℃培養16-19天可產生3.2×10^4-3.5×10^4 conidia/leaf disc 之分生孢子，發芽率22.5-33.5%，12 及28℃產孢量較少且發芽率較低，而8及32℃的環境下無法產孢。
Single conidium of Podosphaera xanthii, causal agent of powdery mildew of muskmelon, were isolated from colonies on diseased leaves and cultured on the leaf disks of muskmelon for purification and production of conidia.
