| 中文摘要 | 經幼苗生長測試法檢測,顯示水稻種子被Phyllosticta glumarum感染率, 和種子在2洋菜或土壤中之發芽率呈顯著負相關。種子處理拮抗細菌,S1及B501, 可提昇發芽率;S1如配合甲基纖維素及泥炭土一併處理種子,更可提昇水稻之發 芽率。50℃之溫水雖然可以降低種媒P.glumarum數量,但卻無法提昇其發芽率。 億力於1ppm濃度時即可抑制P.glumarum之生長,以1pp血億力處理水稻種子,即 可明顯地降低種媒P.glumarum數量,並將種子發芽率由55增加至77。 |
| 英文摘要 | Based upon growing-on test, the amount of rice seed-borne Phyllostictaglumarum was significantly negative correlated with the germination rate on2 wate agar and erroergence rate from field soil. Diseased seed treated witheither antagonistic bacteria, S1 or B501, had higher germination rate thanuntreated control. Apply SI with methyl cellulose and peat could evenimprove better germination rate than apply S1 alone. Although hot water(50℃) treatment reduced the amount of seed-borne P. glumarum, thegermination rate had not significantly different from untreated control. Oneppm benomyl was able to inhibit the growth of P. glum.arum on/in culturalmedium, and was able to significantly reduce the amount of seed-borne P.glumarum and increase the germination rate from 55 to 77. |
