Abstract
1.本病害常發生於濕冷之季節而普遍侵害葉部。
2.引起本病之病原菌為 Pseudomonas glycinea Coerper係種子著生菌，也可經由病葉感染，培養基斜面培養時，呈現綠色之螢光。
3.病原菌呈短桿狀、Gram陰性菌、非抗酸性、單極鞭毛。
4.平面培養時，菌落圓形，邊綠光滑，斜面培養時，菌體呈小棘狀、液體培養基培養時，表面呈環狀。
5.病原菌發育之最適溫度為28~30℃最低溫度為5℃最高溫度40℃。
6.病原菌發育之適當pH值為pH 6.0~7.4。
7.大豆品種三國及臺大高雄五號較為抗病，臺農二號及64-91則較為罹病。
This report deals with one of the most important bacterial disease of soybean caused by Pseudomonas glycinea Coerper. The results obtained are summarized as follows.
1. Bacterial blight of soybean is more serious during periods of cool weather and fre quent rains especially in spring season of cultivated soybean field.
2. The disease is caused by Pseudomonas glycinea Coerper which are seed-borne and can survive also in diseased leaves from growing season to the next.
3. The pathogen is short rod in shape and showed reactions of Gram negative, non-acid fast stain, single flagellum.
4. The culture of the organism shaped circular, echinulate and ring forms in agar colo ny, agar stroke and nutrient broth respectively.
5. The optimum temperature of the pathogen are 28℃-30°C, minmum 5°C, maximum 40°C.
6. The optimum pH value for the development of the pathogen are between 6.0-7.4.
7. Varieties of Sanko and TuKH No. 5 are less suceptible than Tainung No. 2 and 64-91.
