以TMV-om为对照,测定了辣椒上5个烟草花叶病毒分离物P-9、P-38、P-44、P-71、TMV-wym在42个辣椒品种、品系上的致病反应,结果表明这5个分离物对辣椒的致病性存在明显差异:P-71、TMV-wym>P-9>P-38、P-44;对接种过5个TMV分离物的辣椒(四平头)进行过氧化物酶(POD)和酯酶(EST)同工酶分析,结果表明辣椒上5个TMV分离物引起的酶活性有差异:导致POD上活性强弱为TMV-wym>P-9、P-38>P-44、P-71;引起EST活性强弱为P-38>TMV-wym、P-44>P-71>P-9。说明北疆地区辣椒上TMV存在着分化。
TMV-om was used as a control to determine the pathogenic responses of five tobacco mosaic virus isolates P-9, P-38, P-44, P-71 and TMV-wym in 42 capsicum cultivars The results showed that there were significant differences in the pathogenicity of the five isolates against pepper: P-71, TMV-wym> P-9> P-38 and P-44; (POD) and esterase (EST) isozymes. The results showed that the five TMV isolates in pepper caused different enzyme activities: the activity of POD and TME was TMV-wym> P- 9, P-38> P-44 and P-71. The EST activity was P-38> TMV-wym, P-44> P-71> P-9. It shows that there is differentiation of TMV in pepper in northern area.
