| 2. | Cause and control of fusarium oxysporum under the condition of soilless cultivation 无土栽培黄瓜枯萎病的发生及防治 |
| 3. | A carboxyl - phenazine produced pseudomonas m18 controls cucumber wilt disease caused by fusarium oxysporum 18分泌羧基吩嗪抑制黄瓜枯萎病害 |
| 4. | This suggested that inoculating bacillus spp . could increase sweet potato ' s resistance to fusarium oxysporum f . sp . batatas 说明接种芽孢杆菌可有效增强甘薯抵御蔓割病菌的能力。 |
| 5. | Antibiotic 5102 - iii , whose structure is unknown , is useful for the control of cotton wilt caused by fusarium oxysporum 5102 ?号抗生素的理化性质不明,但它对棉花枯萎病菌有很好的防治效果。 |
| 6. | The antimicrobial characters of the fermenting liquor of bc98 - b cereus and its antifungal crude extraction on fusarium oxysporum f sp cucumerinum owen 发酵液与抑菌粗提物对黄瓜枯萎病菌的抑菌特性研究 |
| 7. | Using bacillus spp . strains 25 - 6 、 25 - 9 as materials , the starting mechanism of protective enzyme system in the process of inoculating baccillus spp . to increase sweet potato ' s resistance to fusarium oxysporum f . sp . batatas was investigated 摘要以芽孢杆菌菌株25 - 6 、 25 - 9为材料,研究了通过接种芽孢杆菌提高甘薯对蔓割病保护酶系统的启动机制。 |
| 8. | 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 结果表明:接种芽孢杆菌菌株后,甘薯蔓割病病原菌含量下降,同时甘薯叶片的mda含量也降低,植株的活性氧保护酶系统代谢水平提高;但处理组的甘薯叶片活性氧保护酶系统代谢水平下降。 |
| 9. | 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号生理小种接种香蕉苗后,观察发现:香蕉苗在发病初期出现了黄叶、球茎组织变褐症状;发病中期出现了叶片萎蔫、球茎组织变褐、假茎可见斑点状或线条状褐色病变、根变黑褐症状;发病后期出现了植株萎蔫、枯死等症状。 |
| 10. | 16 replacement plasmids for two different regions were obtained , but have n ' t been introduced into 10 - 22 successfully . 42 cosmids in this region were introduced into a heterogeneous host zx64 , one transformant exhibited a very faint inhibit activity against fusarium oxysporum when growed on a medium with thiostrepton 将300kb区域的柯斯质粒进行异源表达,发现有一文库质粒5h4的转化子在硫链丝菌素存在时表现出对棉花枯萎病菌微弱的抑制活性;无硫链丝菌素存在时,则检测不到。 |
