The time course of auxin-induced ethylene production was determined in mesocotyl segments of etiolated sorghum (Sorghum bicolor L. Moench) seedlings. The latent period between addition of auxin and a detectable rise in ethylene release was 15 to 20 minutes in four different genotypes. This may indicate that the initial effect of auxin on ethylene production is too rapid to involve synthesis of an ethylene-producing enzyme. The technique devised for these experiments involves placing tissue segments end to end in a glass tube, and it allows simultaneous determination of growth and ethylene production.
在黄化高粱（Sorghum bicolor L. Moench）幼苗的中胚轴切段中测定了生长素诱导乙烯生成的时间进程。在四种不同基因型中，添加生长素与乙烯释放可检测到的升高之间的潜伏期为15至20分钟。这可能表明生长素对乙烯生成的初始作用太快，无法涉及乙烯生成酶的合成。为这些实验设计的技术包括将组织切段首尾相连地放置在玻璃管中，并且它允许同时测定生长和乙烯生成。
