| 摘 要： | 对42个苹果栽培品种叶片褐斑病进行了田间发病状况调查与抗性鉴定，分析了叶片气孔密度和大小与抗病性之间的关系，同时研究了不同抗性品种离体叶片接种病原菌后超氧化物歧化酶（SOD）、多酚氧化酶（vPo）、过氧化物酶（POD）、苯丙氨酸解氨酶（PAL）活性和木质素含量的差异变化。依照抗性分级标准，供试材料中抗病品种有14个（其中高抗品种2个），感病品种有28个（其中高感品种7个）；叶片气孔密度与病情指数之间存在显著正相关，相关系数r=0．683；叶片接种后，诱导了4种酶活性和木质素含量的升高，抗病和感病品种的SOD和PP0活性无显著差异，而抗病品种的POD和PAL活性以及木质素含量显著高于感病品种。苹果叶片的气孔密度、POD和PAL的活性以及木质素含量与褐斑病抗性有关。

| Abstract: | Survey on incidence of apple brown spot(Marssonina mali) in 42 apple(Malus domestica) cultivars grown in the open field was conducted and their resistance to apple brown spot was evaluated in the present study.Among the cultivars tested,14 cultivars were found to be resistant,of which 2 were highly resistant,while the rest 28 cultivars were susceptible,7 of which were highly susceptible.The resistance of the cultivars to the disease was positively correlated with leaf stomata density,the coefficient being 0... |
