摘要 马铃薯是全球第四大粮食作物,具有较高的经济价值。其中,马铃薯种薯是马铃薯育种和繁殖的重要研究部分,对马铃薯研究和应用具有重要的意义。为了探究赤霉素(Gibberellin,GA)与丁酰肼(B9)对马铃薯种薯生长发育的影响,采用不同浓度的赤霉素与丁酰肼进行正交实验,最后通过对马铃薯的株高、侧芽、叶片、种薯数量以及种薯淀粉含量的统计。结果显示,GA与B9同时添加对马铃薯种薯的生长发育有明显的影响,对种薯数量和质量的影响显著大于单方面施加GA或B9。其中添加0.5mg/L的GA与20-40 mg/L B9的培养基有助于形成叶片宽大,茎秆粗壮,种薯数量多,种薯淀粉含量高的马铃薯。 Potato is the fourth largest food crop in the world and thus possesses high economic value. Potato tubers are an important partof the research on potato breeding and reproduction,which is of significance on the research and application of potato. In order to explore theeffects of gibberellin(GA)and butyryl hydrazine(B9)on the growth and development of potato tubers,different concentrations of GA andB9 were used for orthogonal experiment. Based on the statistics results of potato plant height,lateral shoots,leaves,tubers' number,andtuber starch content,the effects of adding both GA and B9 on the growth and development were significant,and especially significantly greaterthan that of adding GA or B9 alone on the number and quality of potato tubers. Moreover,the addition of 0.5 mg/L GA and 20-40 mg/L B9 medium contributed to the formation of potatoes with large leaves,stalks,tuber number and tuber starch content.
