研究表明玉米弯孢霉叶斑病菌在活体内外可以产生一系列的细胞壁降解酶 (PG、PMG、Cx) ,并且几种酶的产生有一定的时间顺序 ,首先是PG和PMG的产生 ,PG活性高于PMG的活性 ,而纤维素酶的活性变化不大 ,而且活性相对较弱。对掖单 13和沈试 2 9的损伤率 ,表明感病品种被损伤的程度比抗病品种强 ,而且PG对两个品种的影响较为明显。说明PG在弯孢菌中起主要作用 Studies have shown that Curvularia cornucopiae can produce a series of cell wall degrading enzymes (PG, PMG, Cx) in vivo and in vitro, and the generation of several enzymes have a certain chronological order, first PG and PMG production, PG activity Higher than the PMG activity, while the activity of cellulase little changed, and the activity is relatively weak. The damage rate of Yedan 13 and Shen 2 29 showed that the susceptible cultivars were more damaged than the resistant cultivars, and the effects of PG on the two cultivars were more obvious. PG plays a major role in Curvularia
