| 摘 要： | 在葡萄霜霉病盛发期,通过田间自然鉴定和对感病前后叶片中PPO、PAL的活性进行测定,研究紫珍香自交后代的6个株系对霜霉病的抗性。结果表明:PPO、PAL 2个防御酶活性与供试葡萄抗性间存在正相关,6个供试株系对霜霉病的抗性存在显著差异,其中08-88的抗性最强,显著高于抗病亲本紫珍香;08-420、8-51的抗病性中等;08-1410、8-960、8-13的抗病性最弱,且显著低于对照。

| Abstract: | During the major onset of Plasmopara viticola,the resistance of six strains tested from Zizhenxiang grape variety self progenies to Plasmopara viticola was studied by means of natural infection investigation in field and determining the PPO and PAL activities in leaves before infection and after infection.The results showed that there was positive correlation between the resistance of grapevines tested and activities of PPO and PAL.The resistance of strains tested existed significantly different.The resista... |
