- 摘要:
- 测定了生防菌R13对水稻纹枯病病原菌的抑菌率、菌丝的抑制作用以及对菌核萌发与形成的影响。结果表明:生防菌R13对水稻纹枯病病原菌具有一定的抑制作用,抑菌率为67.8%,可以导致正常的纹枯病菌丝体发生扭曲、变形、原生质外溢,经生防菌R13处理后的菌丝萌发指数为34.6,并且明显延迟了菌核的形成时间。
- Abstract:
- Horsebean root tips were selected as materials to detect micronucleus causing by polymer-flooding waste water sampled from four oil production plants in Daqing city.The results showed that at certain concentration,the four samples all could incite Vicia faba root tip cells to produce chromosomal abnormalities such as fragments,bridge and lagging chromosomes.All these results proved that there was great genotoxicity to organisms caused by oil produced water,and therefore could not discharge it to ecological environment arbitrarily in order to avoid causing great harm.
