Abstract

Results of fluorescence microscopic research and quantitative luminescent analysis of pathogen induced callose accumulation in winter wheat seedlings of two cultivars different in resistance to eye spot causal agent are presented. Higher content of constitutive callose in intact seedlings of unsusceptible cultivar at the initial stages of vegetation was determined. It correlates with resistance of this cultivar to the eye spot causal agent. The increased pathogen induced accumulation of callose in seedlings of susceptible cultivar is revealed, but didn’t influence it protection against pathogen.

病原菌诱导小麦幼苗胼胝质积累作为机械保护屏障的时间过程研究。
介绍了两种对眼斑病原菌抗性不同的冬小麦品种病原菌诱导的冬小麦幼苗胼胝质积累的荧光显微研究和定量发光分析结果。不敏感品种的完整幼苗在植被生长初期具有较高的组构胼胝质含量。这与该品种对眼斑病菌的抗性有关。病原菌诱导的愈伤组织积累增加,但不影响其对病原菌的保护作用。
