Dormant potato tubers (Solanum tuberosum L.) of two cultivars were treated with various concentrations of ethylene gas for various exposure periods. As has been shown by others, ethylene caused a rapid but transient increase in respiration rate, which appeared to be independent of any effects on dormancy. All concentrations tested caused accelerated sprouting, 2 microliters per liter being the most effective. Ethylene exerts a dual effect on potato tubers: it markedly shortens the duration of rest, but it inhibits elongation of the sprouts during extended treatment. Comparing these results with published work on seeds, bulbs, and corms suggests that ethylene must have a significant but as yet unexplained role in rest and dormancy. However, since the most effective ethylene treatment did not equal the response elicited by treatment with ethylene chlorhydrin, other factors must also contribute to termination of rest.
休眠的马铃薯块茎（Solanum tuberosum L.）经过不同浓度的乙烯气体处理和不同时间的暴露。正如其他人所表明的那样，乙烯导致呼吸速率迅速但短暂地增加，这似乎与休眠无关。所有测试的浓度都导致了加速发芽，2 微升/升是最有效的。乙烯对马铃薯块茎有双重作用：它显著缩短了休眠期，但在长时间处理时抑制了芽的伸长。将这些结果与已发表的关于种子、鳞茎和球茎的研究进行比较表明，乙烯在休眠和休眠中必须发挥重要但尚未解释的作用。然而，由于最有效的乙烯处理并不等同于用乙烯氯水解产物处理所引起的反应，因此其他因素也必须有助于休眠的终止。
