[目的]研究不同植物生长调节剂对马铃薯还原糖及淀粉含量的影响.[方法]在大田栽培条件下,以马铃薯(Solanum tuberosum L.)荷兰212为材料,叶面喷施不同植物生长调节剂,通过比较叶片、匍匐茎及块茎内还原糖和淀粉含量的变化,研究喷施植物生长调节剂对马铃薯碳代谢的调控效应.[结果]2-N,N-二乙氨基乙基己酸酯(DTA-6)可以显著降低取样末期匍匐茎内淀粉和还原糖的含量,同时还能降低块茎内还原糖的含量,提高叶片内还原糖的积累;烯效唑(S3307)可以极显著提高块茎内淀粉积累并极显著促进取样末期匍匐茎内淀粉的转移,而且还可降低取样后期块茎内还原糖的含量、极显著提高叶片内淀粉的积累;SOD模拟物SODM与S3307的效果相似.[结论]该研究结果对了解植物生长调节剂的作用机制及促进植物生长调节剂在马铃薯上的应用具有重要意义.

[Objective] The aim was to investigate the effects of plant growth regulators on contents of reducing sugar and starch in potato (Solanum tuberosum L.). [Method] A potato cultivar named 'Holand-212' with three treatments by spraying Diethyl aminoethyl hexanoate (DTA-6), Uniconazole (S3307) and SOD mimics (SODM) were employed to compare differences of the contents of reducing sugar and starch in potato leaves, stolons and tubers in a field experiment. [Result] DTA-6 treatment could significantly reduce the contents of starch and reducing sugar in potato stolons in the period of 100-110 d after seeding, and it could also reduce the content of reducing sugar in tubers, but there is an opposite result in leaves in the same period, significantly. S3307 could extremely significantly increase the content of starch, and can promote the transfer of starch in stolons, in addition, it also could reduce the content of reducing sugar in tubers, and extremely significantly increase the content of starch in leaves at the 110 d after sowing. Moreover, there is a similar effect between SODM and S3307. [Conclusion] The research results are significant for understanding mechanisms of plant growth regulators and promoting application of plant growth regulator in potato.
