ABSTRACT

In plant production that produces high-value products, biostimulants are gaining more and more importance. Research hypothesis; biostimulants can contribute to the change of vitamin C content in edible potato tubers. This hypothesis was verified in a three-year field experiment. The effect of four variants of the use of biostimulators: BrownBio Gold (auxin and cytokinin), GreenOk (humic substances), Kelpak SL (Ecklonia maxima), Titanit (titanium) in tubers of three potato cultivars on the content of vitamin C. The applied biostimulants had a significant impact on the content of vitamin C. The highest increase of this component was found in tubers harvested from the plots sprayed with BrownBio Gold. Vitamin C content under the influence of biostimulants was on average 205.0 mg·kg⁻¹ of fresh weight. Hydrothermal conditions prevailing in the years of the research were the factor that significantly modified the content of the analysed component.

摘要

在生产高价值产品的植物生产中，生物刺激素越来越重要。研究假设；生物刺激素可促进食用马铃薯块茎中维生素 C 含量的变化。这一假设在为期三年的田间试验中得到了验证。使用生物刺激剂的四种变体：BrownBio Gold（生长素和细胞分裂素）、GreenOk（腐殖质）、Kelpak SL（Ecklonia maxima）、Titanit（钛）在三个马铃薯品种的块茎中对维生素 C 含量的影响。施用的生物刺激素对维生素 C 的含量有显着影响。从喷洒了 BrownBio Gold 的地块收获的块茎中发现这种成分的增幅最大。生物刺激素作用下维生素C含量平均为205.0 mg·kg ^-1鲜重。研究期间盛行的热液条件是显着改变分析组分含量的因素。
