摘要
板栗6个不同品种的果实对炭疽病的抗性差异显著,对与抗性有关的过氧化氢酶、过氧化物酶、过氧化物酶同工酶及SOD同工酶的分析表明:过氧化氢酶及过氧化物酶活性与板栗果实抗病性密切相关;过氧化氢酶活性越低,过氧化物酶活性越高,果实的抗性越强;过氧化物酶同工酶及SOD同工酶谱在一定程度上表明了品种间果实的抗性差异.
It was indicated by isozyme analyses that the resistance of the fruits of six different strains of Castanea mollissima to Collelotrichum gloeosporioides was significantly different. The study showed that the activities of peroxide and hydrogen peroxide were closely related to resistance of the fruits of Castanea mollissima to Collelotrichum gloeosporioides. The resistance of different Castanea mollissima strains increased with the activity decrement of hydrogen peroxide, and with the activity increment of peroxide. The isozymes of hydrogen peroxide and SOD also responded to different resistance of different strains of Castanea mollissima. to Collelotrichum gloeosporioides.
