摘  要:
用玉米黄斑病菌Curvularialunata无菌培养滤渡进行生物测定的结果表明,无菌培养滤波处理的,离休叶圆片四周有较大范围的褪绿区;活体植株叶片上产生水清状褪绿晕斑,与病原菌所致的症状相同;种子根的伸长受到明显抑制,证明C.lunata在人工培养过程中可以产生致病毒素。这种毒素是对热稳定的物质。关于C.lunata致病毒素尚属首次报道,作者将其命名为C1毒素。

摘  要:
The cultural filtrate of C. lunata significantly inhibited the growth of roots and caused the same symptom on leaves aroused by the pathogen. The experimental results showed that C. lunata could produce pathotoxin in vitro. It is stable at 100℃ for 10 min..The pathotoxin of C. lunata is reported for the first time, thus it is named Cl-toxin by the authors.
