Result Based on directly regenerated plant of in vitro plant of Xinjiang cotton, the cotton epicotyl treated by pre-culture for 3-5 d was immersed in bacteria for 15 min and co-cultured for 2 d. Cephalothin at 100 mg/L was used to inhibit bacteria after 50 mg/L kan selection. And the combination of cytokinin with relatively high content and auxin with low content was used in its directly budding culture to obtain resistant seedlings.

结果］在新疆棉花离体培养植株直接再生植株基础上，经3~5d预培养处理过的棉花上胚轴，在浸菌15 min共培养2 d后，经50 mg/L kan筛选，用1000 mg/L头孢霉素抑菌，并用相对高含量细胞分裂素和低含量生长素的组合对其进行直接出芽培养，从而获得抗性小苗。

Were analyzed under different nutritional levels. The results showed that in tuber development, under- or over-supply of nutrients reduced ZT content at initial stage and IAA, ABA and JA content at middle stage, but increased GA 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。
