摘要

從台灣各重要水稻生產區域，收集到55個種子樣品，供作種子健康檢查；利用吸濕紙及冷凍吸濕紙法檢測，在此等樣品上共檢測出25種不同的真菌，其中Ascochyta oryzae, Acremoniella atra, Alternaria tenuis, Curvularia affinis, C. brachyspora, C. clavata, C. pallescens, Diplodia oryzac, Drechslera halodes, D. poae, D. rostrata, Fusarium lateritium, F. semitectum, Rhynchosporium ozyzae,及Trichoconis padwickii在本省是第一次從水稻種子上被分離出。種媒真菌中，Phoma glumarum 及 R. oryzae在從北部及東部所收穫的水稻種子上，比其他地區者多；而C. lunata 及 T. padwickii則在採收於中部及南部地區的水稻種子上，比採自於其他地區者多。

Fifty-five rice samples were collected from several seed lots obtained from major rice growing areas in Taiwan for this study. Twenty-five different fungi were found on these seeds by means of blotter and deep-freezing blotter methods. Among those. Ascochyta oryzae, Acremoniella atra, Alternaria tenuis, Curvularia affinis, C. brachyspora, C. clavata, C. pallescens, Diplodia oryzac, Drechslera halodes, D. poae, D. rostrata, Fusarium lateritium, F. semitectum, Rhynchosporium ozyzae, and Trichoconis padwickii were isolated from rice for the first time in Taiwan. Phoma glumarum and R. oryzae occurred more on rice seed harvested from northern and eastern Taiwan than central and southern Taiwan. Curvularia lunata and T. padwickii occurred more on rice seed harvested from central and southern than from northern and eastern Taiwan.
