The results indicate that the low level resistance to tribenuron-methyl in the biotype of Galium aparine from Xuchang, Henan Province, is based on the excessive expression of ALS and the enhancement of tribenuron-methyl metabolism resulting from GSTs, not due to the sensitivity of ALS. In the meanwhile POD and SOD may play a role in alleviating the spray injury.

抗药性生物型猪殃殃对苯磺隆产生抗性的原因可能是ALS过量表达及GSTs对苯磺隆的代谢作用加强，而不是由于ALS的敏感性下降，同时POD、SOD在减轻药害中也具有一定作用。
