研究了水稻品种“秀水04”的稻瘟病菌亲和菌株中A49和非亲和菌株中E3以及“秀水48”的亲和菌株中E3和非亲和菌株中G1在互作中产生的诱导侵染作用。混合接种的诱导侵染作用随亲和菌株菌量的增加而增强;先接强小种后接弱小种或先接弱小种再接强小种均能产生诱导侵染作用,作用强弱随接种间隔时间长短而不同;少量的亲和菌株即有诱导侵染作用,但当非亲和菌株大量存在时有减轻发病的作用。提出,这种诱导侵染作用可能是水稻品种抗性丧失的一个重要原因。
The inoculation induced by interaction between G1 in E49 and non-compatible strain E3 and non-affinity strain G1 in Xiushui 04 affinity strain of Xiushui 04 was studied. Dyeing effect. Inoculation induced by mixed inoculation increased with the increase of mycobacteria; the first access to strong races followed by weak races or followed by weak races followed by strong races were able to induce infection, the strength of the vaccination The length of time between the different; a small amount of affinity strains that have induced infection, but when a large number of non-affinity strains have the role of reducing the incidence. It is suggested that this induced infection may be an important reason for the loss of resistance in rice varieties.
