Their biological activity is generally attributable to inhibition of NADH: ubiquinone oxidoreductase activity and thereby mitochondrial respiration.

这一类化合物之所以具有很好的杀虫活性，是由于对还原型烟酰胺腺嘌呤二核甘酸的抑制作用而阻断了线粒体的呼吸。

The potential sources of NO in plants include nitric oxide synthase, nitrate reductase, xanthine oxidoreductase and the nonenzymatic pathway.

在植物中， NO的潜在来源包括一氧化氮合成酶、硝酸还原酶、黄嘌呤氧化还原酶和非酶促途径。

The variance of ABA of grape during storage were discussed in this paper.The following results are been drawn:the change of the content of ABA of grapes during storage characterizes by a parabolic shaped curve with obvious peak.Low temperature (0±0.5℃) is conducive to delaying the appearance of the peak of ABA and reduces the peak value.Nine kinds of plant growth regulators and two kinds of chemicals were chosen to treat grape bunches so as to study their mechanisms on ABA of grapes,2,3,5 triiodobenzoic a...

试验研究了葡萄贮期脱落酸的变化，结果表明：葡萄贮期 ABA含量呈抛物线形变化，有明显的高峰出现，低温( 0± 0 。5℃)贮藏具有推迟 ABA峰期和降低峰值的作用，经用 9种植物生长调节剂和 2种化学药品对葡萄果穗处理试验，三碘苯甲酸对 ABA的形成有极强的抑制作用，吲哚- 3-乙酸、赤霉素( GA3)、萘乙酸和 6-苄基氨基嘌呤( 6- BA)对 ABA的形成也具有拮抗作用，矮壮素、比久( B9)、乙烯利和外源脱落酸对 ABA的形成有促进作用。
