最近，美农业研究局的研究者研究出一种人工合成的防御物质，该物质为BTH（或苯并座二喷）O它不是农药，但在试验中，仅喷洒极少的四H，就可刺激小麦、玉米、水稻。黄瓜和其它作物产生极强的生化抗性。据研究者介绍，该物质可改变诸如见了质酶、葡聚糖酶和过氧化物酶蛋白质的水 Recently, researchers from the Agricultural Research Service of the United States of America have developed a synthetic defensive substance called BTH (or benzogroup) O, which is not a pesticide but in experiments it was sprayed with only very few tetra Can stimulate wheat, corn, rice. Cucumber and other crops produce strong biochemical resistance. According to the researchers, the substance can change the water such as the metase, glucanase and peroxidase proteins
