4-（2-（4，6-二甲氧基嘧啶-2-基氧基）苄氨基）苯甲酸丙酯（ZJ 0273）是一种抑制乙酰乳酸合成酶（ALS）的新型除草剂。ZJ 0273对环境安全，对油菜田杂草防除效果满意。ALS是总氨基酸（TAAs）特别是支链氨基酸（BCAAs）生物合成的关键酶。采用近红外光谱技术研究了ZJ 0273对油菜叶片中BCAAs和TAAs的影响。TAAs和BCAAs含量随着除草剂用量的增加而降低，随着叶片衰老，TAAs和BCAAs的含量沿着增加。选择2，416和1，340 nm波长建立了检测BCAA和TAAs的NIRS模型，模型预测集的相关系数分别为0.9823、0.9764、0.9831和0.9968。结果表明，100 mg/L的ZJ 0273对油菜的氨基酸含量没有显著影响，是一个安全剂量。
Propyl 4-(2-(4,6-dimethoxypyrimidin-2-yloxy) benzylamino)benzoate (ZJ0273) is a new herbicide which inhibits acetolactate synthase (ALS). The ZJ0273 is considered as safe for the environment and exhibits a satisfactory effect on weed control in the rapeseed field. ALS is the key enzyme of reactions in the biosynthesis of total amino acids (TAAs) especially branched-chain amino acids (BCAAs). This study reports the effect of ZJ0273 on BCAAs and TAAs in rapeseed leaves using near-infrared spectroscopy (NIRS) techniques. A decrease in TAAs and BCAAs contents was observed as the herbicide dosages were increased along with leaf senescence. The wavelengths 2,416 and 1,340 nm were selected to develop the NIRS model for detecting BCAAs and TAAs, and correlation coefficients of model’s prediction set were 0.9823, 0.9764, 0.9831, and 0.9968 for valine, isoleucine, leucine, and TAAs, respectively. The results indicated that 100 mg/L ZJ0273 was a safe dosage for oilseed rape as it did not show a significant effect on the contents of amino acids compared to other higher dosages (500 and 1,000 mg/L).
