摘要: Identification and mechanism of Echinochloa crus-galli (L.) resistance to fenoxaprop-p-ethyl via physiological anatomical differences between susceptible resistant were investigated. The that take into account growth reduction, chlorophyll content lamina thickness, xylem vessel diameter in both biotypes E. crus-galli. results showed the reduction fifty (GR50) biotype was 12.07-times higher than treated with fenoxaprop-p-ethyl. highly reduced relative one An test significant cytology respect thickness diameter. may be due faster metabolism below physiologically active concentration or insensitivity its target enzyme (Acetyl-CoA carboxylase).
