乙烯（约100 μl/L）显著刺激甘薯根切片衰老过程中线粒体粗组分的呼吸活性、细胞氧化酶和琥珀酸脱氢酶活性以及线粒体膜蛋白的活性，表明乙烯刺激损伤组织中线粒体的发育。即使当切片在不存在其的情况下预老化1天并且之后在其存在下老化时，其也具有这样的效果。在含乙烯空气中老化的切片的线粒体内膜比新鲜切片的致密，而在无乙烯空气中老化的切片的膜较轻。氯霉素完全抑制细胞氧化酶活性的增加，无论切片在乙烯存在或不存在下老化。环己酰亚胺没有抑制在无乙烯空气中老化的切片的增加，但在含乙烯空气中老化的切片中增加了50%。
Ethylene (about 100 μl per liter) markedly stimulated increases in respiratory, Cytcoxidase and succinate dehydrogenase activities of the crude mitochondrial fraction as well as mitochondrial membrane protein during aging of sliced sweet potato root tissue, indicating that it stimulated mitochondrial development in wounded tissue. It had such an effect even when slices were pre-aged in its absence for 1 day and thereafter aged in its presence. The mitochondrial inner membrane from slices aged in ethylene-containing air was denser than that from fresh slices, while the membrane from slices aged in ethylene-free air was lighter. Chloramphenicol completely inhibited the increase in Cytcoxidase activity whether slices were aged in the presence or absence of ethylene. Cycloheximide did not inhibit the increase in slices aged in ethylene-free air, but did by 50% in those aged in ethylene-containing air.
