Banana seedlings inoculated with fusarium oxysporum f . sp . cubense race 4 appeared some symptoms , such as yellow leaves , browning corm tissue ( occured in the earlier period ) , wilting leaves , browning corm and pesudostem tissue , blacking roots ( occured in the middle period ) , and wilting , dying plants ( occured in the latter period ) 摘要用枯萎病菌4號生理小種接種香蕉苗后,觀察發現:香蕉苗在發病初期出現了黃葉、球莖組織變褐癥狀;發病中期出現了葉片萎蔫、球莖組織變褐、假莖可見斑點狀或線條狀褐色病變、根變黑褐癥狀;發病后期出現了植株萎蔫、枯死等癥狀。

The results were as follows : for the sweet potato leaves treated with baccillus spp . inoculation , the transpiration rate and stomatal conductance were both significantly higher than those of the control , which decreased with the increase of fusarium oxysporum f . sp . batatas content ; the mda content decreased , thus the metabolism of the plant active oxygen protective enzyme system increased ; whereas the metabolism level of active oxygen protective enzyme system decreased 結果表明:接種芽孢桿菌菌株后,甘薯蔓割病病原菌含量下降,同時甘薯葉片的mda含量也降低,植株的活性氧保護酶系統代謝水平提高;但處理組的甘薯葉片活性氧保護酶系統代謝水平下降。

In terms with the principle of fusarium oxysporiun caused plant disease : bundles were blocked and fusarid acid killing cells was formed by hyphae so that caused water metabolism abnormal and plant wilting . in order to find out effective method of anti - fiisarium oxysporuin , long ya lillium was taken as material with plant tissue culture and genetic transformation techniques in this paper 針對尖孢鐮刀菌的致病機理:菌絲阻塞維管束引起水分代謝失常和菌絲在植物體內產生毒素(鐮刀菌酸)損害膜結構造成代謝失常,從而導致植物萎焉。本實驗以龍牙百合為研究對象,應用細胞工程中的離體培養方法并結合轉基因技術,以期找到抗尖孢鐮刀菌的有效途徑。
