Were analyzed under different nutritional levels. The results showed that in tuber development, under-or over-supply of nutrients reduced Zeatin content at initial stage and indole actic acid, abscisic acid and jasmonic acid content at middle stage, but increased gibberellins content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.

结果表明，过低、过高的营养供给，降低了块茎发育前期细胞分裂素的含量，中期细胞生长素的含量以及促进块茎发育的脱落酸、茉莉酸含量，增加了各时期促进匍匐茎发生的赤霉素含量，导致在块茎形成和膨大的关键时期，GA/ABA和GA/JA比值失衡，抑制了块茎的正常发育。
