摘要
用辣椒疫病菌生理小种ph3人工接种抗疫病的辣椒品系A5、A3和感病品系EC,并用生理小种ph1接种抗病品系A3,接种后分别测定和分析植株体内苯丙氨酸解氨酶(PAL)、多酚氧化酶(PPO)、β-1,3-葡聚糖酶(β-1,3-glucanase)和几丁质酶(Chitinase)活性的变化。结果表明:接种疫霉菌后,抗病品系与感病品系体内4种酶的活性有明显差异,并显示出辣椒品系的抗病性与植株体内的多酚氧化酶活性、苯丙氨酸裂解酶活性、β-1,3-葡聚糖酶和几丁质酶活性呈正相关。
In order to study the physiological and biochemical characteristics of pepper after inoculation the Phytophthora capsici,the changes of activity about phenylalanine ammonia lyase（PAL）,polyphenol oxidase（PPO）,β-1,3-Glucanase and chitinase were mensurated.The results showed that the changes of these protective enzymes＇activities were remarkable difference between different resistance pepper lines.There was a positive correlation between the activities of phenylalanine ammonia lyase（PAL）,polyphenol oxidase（PPO）,β-1,3-Glucanase and chitinase and the pepper resistance to Phytophthora capsici.
