There is a few reports on regulatory mechanisms of dormancy accompanied by storage organ formation in bulb and rhizome plants, although it is important for agriculture and scientific development to clarify its regulatory mechanisms. It was shown that bulb growth was controlled by temperature in bulblets of Dutch iris. It was demonstrated that lotus plant was able to sense photoperiod in transition to storage organ after 2 weeks of transplanting. It was also suggested that storage organ was formed by decrease in expression levels of glloberellin biosynthesis enzyme gene and increase in expression levels of abscisic acid biosynthesis enzyme gene under short day condition.

有几个报告的休眠伴随着鳞茎和根茎植物贮藏器官的形成，虽然它是重要的农业和科学发展，以澄清其调节机制。结果表明，荷兰鸢尾鳞茎的生长受温度控制。结果表明，在移栽2周后，莲植株能够感受到光周期，并向贮藏器官过渡。短日照条件下，赤霉素生物合成酶基因的表达量降低，脱落酸生物合成酶基因的表达量增加，从而形成贮藏器官。
