摘要
研究了青枯细菌毒性菌株平板培养滤液(PCF)中热稳定性成分对番茄组织培养物的影响结果表明:PCF中含有一类非酶、非胞外多糖(EPS)的热稳定毒性物质,它对番茄叶片脱分化过程有抑制作用,抗病材料较感病材料敏感,另外,它对番茄试管苗生根也起抑制作用;
The effects of the heat stable substance excreted by a virulent strain of Pseudomonas solanacearum on tissue cultures of tomatoes were studied.The results showed that there existed a kind of toxic component in the plateoculture filtrate(PCF),which was demonstrated to be neither enzymes nor extracellular polysaccharide (EPS). This substance was toxic to the differentiation of tomato leaf discs and the rooting of shoots,while EPS had not such effect.
