乙烯是最简单的有机分子之一，具有生物活性。空气中浓度低至 0.1 ppm 时，它已被证明对植物生长和发育具有显着影响 [1]。 Neljubov [78]首先证明乙烯对黄化豌豆幼苗具有三种主要作用，称为三重反应：(1) 顺向生长，(2) 茎增粗并抑制茎伸长，(3) 扩大顶端钩曲率。从那时起，乙烯对光生长植物的许多影响被描述，例如葫芦的性别决定、更年期果实的果实成熟、上位曲率、花衰老和根萌生[1]。有趣的是，乙烯也被证明对某些植物有相反的作用。例如，它会抑制大多数双子叶植物的茎伸长，而在一些水生双子叶植物和水稻中，它会刺激生长[1,45,72]。
Ethylene is one of the simplest organic molecules with biological activity. At concentrations as low as 0.1 ppm in air, it has been shown to have dramatic effects on plant growth and development [1]. Neljubov [78] was the first to show that ethylene has three major effects in etiolated pea seedlings called the triple response: (1) diageotropic growth, (2) thickening of stem and inhibition of stem elongation, and (3) exaggeration of apical hook curvature. Since then, numerous ethylene effects have been described in light-grown plants such as sex determination in curcurbits, fruit ripening in climacteric fruits, epinastic curvature, flower senescence, and root initiation [1]. Interestingly, ethylene has also been shown to have opposite effects in some plants; for instance, it inhibits stem elongation in most dicots, whereas in some aquatic dicots and rice, it stimulates growth [1, 45, 72].
