稻纹枯病

苏化911防治稻纹枯病的研究

Control of sheath blight of rice by " k.c.i. 911 "

稻纹枯病近几年以1997与2000年为害最重，71%的水稻面积不同程度的感染了纹枯病。

In recently years , sheath blight of rice Rhizoctonia solani made the most serious harm in 1997 and 2000 . 71 % of the rice areas were infected by the sheath blight of rice in different degree .

经潮霉素（hygromycin）筛选、PCR分析、抗稻纹枯病和稻瘟病鉴定、GUS活性检测转基因水稻后代，验证了水稻花器介导法转目标基因的有效性。

The validity of target genes transferred by rice floral organ-mediated method were verified by PCR analysis , evaluation of resistance to sheath blight and blast , screening by hygromycin B and examination of GUS activity in transgenic rice .

水稻是我国也是世界的主要粮食作物，稻瘟病和纹枯病的严重发生是影响其产量和品质的重要因素。

Rice is an important food crop all over the world . Rice blast and sheath blight are important diseases influencing rice yield and quality .

但由于病原菌遗传多样性、抗病基因匮乏、育种周期长等因素，使稻瘟病和纹枯病抗病育种成效大大降低。

However , as the result of genetic diversity of nosophyte , absence of resistance genes and long breeding circle in traditional methods , the breeding effect for disease resistance was lower to a great degree .

前人对硅在抵御水稻病害中的研究报道多集中在稻瘟病、纹枯病等由真菌引起的病害，而有关硅对由细菌引起的水稻白叶枯病抗性的研究，国内外鲜见报道。

Previous studies on silicon-enhanced disease resistance in rice were mainly focused on rice blast and sheath blight that were caused by fungi . To date , the effect of silicon on bacterial blight ( Xoo ) has never been reported .

对防治水稻纹枯病具有特效，也可用于水稻稻瘟病，小麦纹枯病的防治。

由于水稻稻瘟病及水稻纹枯病的病害程度是根据距离特征来检测，目前还没有定义数字图像距离的唯一方法。

The harm degree of the rice blast and the rice sheath blight was detected according to the distance characteristic , at present there had not defined the only method of digital image distance .
