Abstract

The effects of gibberellic acid and kinetin with ethylene plus carbon dioxide on the thermodormancy of lettuce seeds (Lactuca sativa L. cv. Mesa 659) at 35 C in the dark were studied. The combination of gibberellic acid plus kinetin with ethylene plus carbon dioxide was most effective in overcoming thermodormancy in these Great Lakes type seeds, alleviating any induced light requirement. Gibberellic acid action required at least a minimal level of ethylene plus carbon dioxide. Kinetin action was independent of ethylene plus carbon dioxide but interacted with the gases when the gases were added. A schematic representation of the interaction is presented.

摘要

研究了黑暗条件下 35℃下赤霉素和激动素与乙烯加二氧化碳对生菜种子(Lactuca sativa L. cv. Mesa 659)热休眠的影响。赤霉素加激动素与乙烯加二氧化碳的组合在克服这些大湖型种子的热休眠方面最为有效,减轻了任何诱导的光照需求。赤霉素的作用至少需要最低水平的乙烯加二氧化碳。激动素的作用独立于乙烯加二氧化碳,但在添加气体时与气体相互作用。提出了相互作用的示意表示。
