选用对葡萄黑痘病抗性不同的３种类型（高抗、中抗、感病）葡萄，研究其正常功能叶、幼叶（感病前期、初期、后期）ＰＯＸ活性及其同工酶谱变化情况。结果表明，叶片ＰＯＸ活性与葡萄抗黑痘病呈正相关。高抗类型ＰＯＸ活性明显高于中抗和感病类型，正常功能叶ＰＯＸ活性高于幼叶；高抗类型与中抗类型ＰＯＸ活性在幼叶感病前后呈上升趋势，而感病类型则呈先升后降趋势。抗性强弱不同嵉睦嘈停校希赝っ赣邢灾钜臁１硐治呖估嘈兔复氖俊⒖矶燃把丈疃染哂诟胁±嘈停徊宦鄹胁±嘈汀⒖共±嘈停溆滓陡胁『竺复俊⑶慷染哂诟胁∏啊 The three types (high resistant, moderately resistant, susceptible) grapes with different resistance to grape anthracnose were selected to study their POX activities and their isozymes in normal and young leaves (early onset, early and late stages) Changes. The results showed that there was a positive correlation between leaf POX activity and grape anti-acne disease. The activity of POX of high resistant type was obviously higher than that of medium resistant and susceptible type, while the POX activity of normal functional leaves was higher than that of young leaves. The activity of POX of high resistant type and moderate resistant type increased before and after susceptible young leaves, while the susceptible type First rise and then decline.
