“…The available literature lacks information on the effect of biostimulants on accumulation of glycoalkaloids in potato leaves. However, in their earlier studies, Zarzecka et al (2013Zarzecka et al ( , 2015 demonstrated that both insecticides and herbicides as well as their mixtures applied in the experiment significantly increased the level of glycoalkaloids in potato leaves. Weather conditions in the study years significantly influenced glycoalkaloid contents; it was the highest in 2012 when the lowest precipitation was recorded during the growing season and the average temperature was by 0.7°C higher than the long-term average, which had also been reported by Zarzecka et al (2015).…”

The objective of the study was to determine the effect of biostimulants and herbicides on the level of glycoalkaloids in leaves and tubers of three table potato cultivars. The following factors were examined: I -potato cultivars: Bartek, Gawin, Honorata; II -five weed control methods (application of biostimulants and herbicides: 1. mechanical weed control -control treatment and four herbicide or herbicide + biostimulant treatments (Harrier 295 ZC, Harrier 295 ZC + Kelpak SL, Sencor 70 WG, Sencor 70 WG + Asahi SL). The potato tuber content of glycoalkaloids was significantly affected by genotype. The highest total glycoalkaloid (TGA) content was determined in cv. Bartek tubers and the lowest in cv. Honorata tubers, on average 92.31 and 91.14 mg/kg fresh matter, respectively. Herbicides applied alone or in combination with biostimulants contributed to an increase in glycoalkaloids determined in both potato leaves and tubers, compared with the control. However, a significantly higher TGA content was found following the application of Harrier 295 ZC only.Keywords: plant resistance; toxicity; weather conditions; tuberous crop; Solanum tuberosum L. 256Vol. 62, 2016, No. 6: 256-260 Plant Soil Environ. Field studies were conducted in soils representing the following type of agricultural land: grey brown podzolic soil of ploughed fields belonging to agronomic category I, the order of brown soils, quality class IVb which represents the rye very good class of agricultural suitability. In 2012 and 2013, soil pH was slightly acidic (5.60) whereas in 2014 it was alkaline (7.35). The organic matter content ranged from 15.0-18.7 g/kg. The available phosphorus (P) content ranged from high to very high, available potassium (K) content ranged from average to very high, and available magnesium (Mg) content was high. Winter wheat crops preceded table potato in each study year. The same organic manuring and mineral fertilisation were applied: 25 t/ha farmyard manure as well as 100 kg/ha N, 44 kg P/ha and 125 kg K/ha. Samples of potato leaves (10 leaves) for chemical analyses were taken during the flowering stage. Potato tuber samples (50 tubers) were collected from the plots during harvest and stored at 10-12°C. Chemical analyses of fresh material were performed so as to obtain three replicates. Glycoalkaloid contents of potato leaves and tubers were determined following the Bergers' method (Bergers 1980). Results of the study were analysed by ANOVA. Significance of sources of variation was checked with the Fisher-Snedecor test and the significance of differences between means was tested using the multiple comparison Tukey's test at the significance level of P = 0.05. Statistical calculations were performed in Excel using own algorithm based on the mathematical model. Values of the Sielianinov's hydrothermal coefficient (K = 0.95) indicate that the year 2012 was slightly dry (Table 1). The precipitation sum amounted to 264.9 mm and was by 10.6 mm lower than the long-term mean whereas the average temperature over the growing...

“…Because of the association of TGA with a bitter astringent taste and their relative toxicity, a generally accepted safe level is 200 mg/kg FM (Storey 2007). Glycoalkaloid levels above 200 mg/kg are considered to pose a risk to human health (Friedman and Levin 2009, Tajner-Czopek et al 2012, Zarzecka et al 2013. The TGA level in tubers is mainly influenced by genetic factors (Friedman and Levin 2009, Peksa et al 2002, Zarzecka et al 2013, weather conditions of a growing season (Zrůst et al 2000, Hamouz et al 2005, Zarzecka and Gugala 2007 and agrotechnical factors (Wierzbicka 2011).…”

Lately, especially, among fans of a healthy diet, increasing attention is paid to the cultivars with red and purple flesh, which are known to have a significantly higher antioxidant capacity, as compared with traditional yellow and white fleshed cultivars .…”

In the three-year field trials (2009)(2010)(2011) at two locations with different altitudes a total of 14 potato cultivars with different colour of flesh (yellow, white, red and purple) were grown. The content of total glycoalkaloids (TGA) was determined by HPLC. TGA content ranged from 18.8 to 102.4 mg/kg fresh matter and none of the cultivars reached the value of risk to human health. Conclusive and decisive influence on the content of the TGA was recorded in genotype. Individual cultivars reached 0.47 to 1.45 of the TGA content in the control cv. Agria. In terms of the colour of the flesh the highest TGA content was found in group of red-fleshed cultivars (1.53 × higher than the average of cultivars with yellow or white flesh); while red-fleshed cv. Rote Emma reached the absolutely lowest TGA content of 14 cultivars, which confirms the decisive role of genotype. On warm, dry habitats in the lowlands a higher TGA content was observed when compared with the amount raised in a typical potato field.

The aim of the study was to determine the influence of herbicide application with biostimulants on total glycoalkaloid (TGA) content in potato leaves and tubers. The study was based on a two-factor field experiment established in a split-plot arrangement in three replications. The factors were as follows: factor I – two cultivars of edible potato – Oberon and Malaga; factor II – five methods of using herbicide and biostimulants: 1. control object; 2. herbicide clomazone + metribuzin (Avatar 293 ZC); 3. herbicide clomazone + metribuzin and biostimulant PlonoStart; 4. herbicide clomazone + metribuzin and biostimulant Aminoplant; 5. herbicide clomazone + metribuzin and biostimulant Agro-Sorb Folium. The herbicide clomazone + metribuzin significantly increased the concentration of glycoalkaloids in potato leaves, and the herbicide used together with the biostimulant Aminoplant significantly reduced the content of TGA in potato leaves compared to the control. The herbicide whether applied with the biostimulants (PlonoStart, Aminoplant, Agro-Sorb Folium) contributed to a reduction in the concentration of glycoalkaloids in tubers compared to the control. Leaves and tubers of the cultivar Malaga were characterised by a significantly lower TGA content than the cultivar Oberon.
