Five strains with strong nematicidal activity were obtained in the analysis with the fermentation liquid extract of some isolates.
室内初步测定了部分菌株的发酵粗提液的杀线虫活性,获得五株杀线虫活性较强的菌株。
The result of bioassay showed that the nematicidal activity was not detected in the acetate or water crude extracts form fruit bodies.
生物学测定结果表明:子实体丙酮和水粗提物均不具有毒杀线虫的活性。
It showed:the nematicidal activity of fraction 2 and fraction7 could baffle it's metabolism and unbalance their oxidation and antioxygenation and make them to die.
这就说明:组分2和7中的杀线活性成分可能阻碍了虫体的新陈代谢,导致线虫体内氧化和抗氧化作用失衡,致使线虫死亡。
A hypothesis that nematicidal activity of quinolizidine alkaloids is mainly determined by types of functional group pair and types of functional group in their molecular structures was proposed.
本文提出了双稠哌啶类生物堿对松材线虫的杀线活性强弱主要受其分子结构中官能团对的类型及其中的官能团的类型控制的假说。
The extract rates of different solvents were obviously different, and it had a certain correlation to that of nematicidal activity of extracts of Xanthium sibiricum.
不同溶剂对苍耳叶的提取率间存在明显差异,且这种差异与不同溶剂提取物杀线虫活性间的差异之间存在一定相关性。
