Abstract

The aim of the study conducted in 2019–2021 was to determine the effect of biostimulants and growth regulators on the yield size and structure, as well as the chemical composition of edible potato tubers. The cultivar evaluated was Vineta. Asahi SL, Kelpak SL, Aminoplant, Tytanit, gibberellic acid (GA3) and Moddus 250 EC were applied in potato cultivation. The application of biostimulants Asahi SL and Tytanit increased the total and marketable tuber yield, as well as the average tuber weight. Aminoplant had a beneficial effect only on the marketable yield, while Moddus 250 EC decreased tuber yield and mean tuber weight, especially under conditions of high rainfall. Biostimulant Asahi SL caused a decrease in the number of tubers formed, while gibberellic acid stimulated tuberisation. Both preparations increased the share of deformed tubers in the total yield. The effect of biostimulants and growth regulators on the formation of the chemical composition of potato tubers was multidirectional. Tytanit increased protein content in tubers, while the remaining preparations, with the exception of the growth regulator Moddus 250 EC, decreased the amount of this component. GA3 and Moddus 250 EC decreased the content of crude fibre and, in the case of Moddus 250 EC, also the content of mineral components. The highest concentration of nitrates (V) was characteristic for potato tubers treated with Asahi SL and the lowest for those treated with Moddus 250 EC.

植物生长调节剂对马铃薯块茎产量和品质的影响

2019年至2021年进行的这项研究的目的是确定生物刺激剂和生长调节剂对可食用马铃薯块茎产量大小和结构以及化学成分的影响。评价的品种是葡萄藤。将Asahi SL、Kelpak SL、Aminoplant、Tytanit、赤霉素（GA3）和Moddus 250 EC应用于马铃薯栽培。生物刺激剂Asahi SL和Tytanit的应用提高了块茎的总产量和市场产量，以及块茎的平均重量。氨基植物仅对商品产量有有益影响，而Moddus 250 EC降低了块茎产量和平均块茎重量，尤其是在高降雨量条件下。生物刺激剂朝日SL导致块茎形成数量减少，而赤霉酸刺激块茎形成。两种制剂都增加了变形块茎在总产量中的份额。生物刺激剂和生长调节剂对马铃薯块茎化学成分形成的影响是多方向的。Tytanit增加了块茎中的蛋白质含量，而除生长调节剂Moddus 250 EC外，其余制剂降低了该成分的含量。GA3和Moddus 250 EC降低了粗纤维的含量，在Moddus 250EC的情况下，还降低了矿物成分的含量。硝酸盐（V）的最高浓度是用Asahi SL处理的马铃薯块茎的特征，而用Moddus 250 EC处理的块茎的硝酸盐浓度最低。
