用白叶枯非亲和性菌株G-3-1,G-3-2,78-3的活/死细胞剪叶法,分别于孕穗期对高感的金刚30和中抗的74-105水稻品种植株的顶部展开叶连续3次（间隔4d）诱导接种,7d后在同一叶片及其上一叶接种亲和性菌株76-25,结果发现两品种的被接种叶及紧接其上的一叶均获得了诱导抗性,活体诱导物较死体诱导物诱导的抗性强,74-105品种获得的抗性较金刚30强,金刚30,74-105及抗病的南粳15经78-3活细胞诱导接种的叶片组织液,对78-3和76-25菌株的生长有显著的抑制作用;抗病品种的正常和受伤叶片组织浓也有抑菌作用,但均较诱导叶弱,从前述3个水稻品种的胚及叶片组织提取凝集素并纯化,经测定,二者对供测的5个白叶枯菌株均...

Suceptible cultivar Jingang 30 and medium resistant cultivar 74-105 were used to test the induced resistance. Alive and dead cells of incompat-ible strains 78-3, G-3-1 and G-3-2 of Xantbomonas campestris pv. oryzae werepre-inoculated respectively on the top expanding leaves three times at a 4-dayinterval at booting stage by clipping method seven days after the last pre-inoc-ulation, the compatible strain 76-25 was inoculated on the same leaves and theleaves closely above. The inoculated leaves of each cultivar were found to bewith induced resistance alike . Such resistance induced by the alive...
