| 摘 要： | 研究了稻白叶枯病细菌在人工培养基上连续转管培养后致病力和胞外酶活性的变异。经长期连续转管培养后,细菌的生长速度、粘多糖产量和蛋白酶活性都有降低的趋势,病菌的致病能力也有不同程度的降低,但纤维素酶活性的变异不显著。血清型也未发生改变.对病菌发生这些变异的机制进行了讨论。

| Abstract: | The variation of the virulence and some biological properties of four isolates of Xanthomonas campestris pv.oryzae were studied by successive culture.The results indicated that the virulence,rate of growth,production of extra-cellular polysaccharide and activities of proteolytic enzyme of the pathogen were rapidly decreased after the successive culture,but there was no distingushed change of extra-cellulase activity and the serotype.The causes of variation of the pathogenic bacterium and its pathogenic mechanism were discussed. |
