“…Whereas, the lowest TGA was determined in the growing season of 2019 with the lowest rainfall. A similar response associated with the weather conditions was reported by other researchers (Żołnowski 2001, Gugała et al 2016, Mystkowska 2019.…”

“…It has been shown that the highest concentration of glycoalkaloids, on average 94.17 mg/kg of fresh matter, occurred in 2020, when rainfall was the highest, and the lowest in 2019, characterised by low rainfall. Similar results were described by Zarzecka et al (2013), Hamouz et al (2014), Mystkowska (2019), Wszelaczyńska et al (2020). Żołnowski (2001) found that high levels of glycoalkaloids occur in plants when metabolism is very intense.…”

“…The lowest TGA content was recorded after clomazone + metribuzin was applied in combination with the biostimulant Aminoplant. The decrease in the content of glycoalkaloids in potato tubers after the application of biostimulants was also observed by Gugała et al (2016) and Mystkowska (2019). Meteorological conditions in the growing seasons influenced the glycoalkaloids content in potato tubers (Table 4, Figure 2).…”

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.

“…Numerous factors affect the formation of glycoalkaloids in potatoes: environmental and growing conditions, maturity during harvesting time, temperature during growth, and extent of sprouting, as well as any mechanical damage such as bruising, cutting, wounding, and slicing while handling. Postharvest storage conditions, especially the wavelength, duration, and intensity of light during storage can also play a crucial role on the glycoalkaloid content of potatoes, while other environmental conditions during packaging, transportation, and marketing can have an effect on it as well [ 48 , 49 ]. A previous study [ 14 ] found no statistically significant changes to the glycoalkaloid content of whole potatoes after HPP treatment.…”

High-Pressure Processing and Ultrasonication of Minimally Processed Potatoes: Effect on the Colour, Microbial Counts, and Bioactive Compounds

HPP at 600 MPa alone, and in combination with US at 20 kHz (200 W), was applied to minimally processed potatoes of two commonly grown cultivars in Ireland. Changes in colour and microbial load (Enterobacteriaceae, total aerobic count, Salmonella, yeasts, and moulds) were monitored in vacuum-packaged potatoes during 14 days of storage at 4 °C. HPP and HPP/US significantly (p < 0.05) affected the colour parameters a*, b*, L*, and ΔE of minimally processed potatoes compared to the controls. Microbial growth was delayed in most of the treated samples with respect to those untreated (controls), while HPP completely inactivated Enterobacteriaceae in both cultivars. Total phenolic content and antioxidant activities were not altered in the treated samples of both varieties when compared to the controls. The levels of chlorogenic acid, ferulic acid, and caffeic acid were decreased after both treatments, with a significant (p < 0.05) increase in quinic acid in the treated samples as opposed to those untreated. A significant (p < 0.05) decrease in the levels of glycoalkaloids, namely α-chaconine and α-solanine, in HPP- and HPP/US-treated potatoes was also observed. These findings suggest that HPP and US can extend the shelf-life of minimally processed potatoes with a negligible impact on their antioxidant activity and phenolic content.

“…This year was characterised by the lowest precipitation −236 mm, lower by 97 mm from the multiannual sum. The stress in potato production alters glycoalkaloid levels [55,56], and the expression of genes associated with glycoalkaloid synthesis are elevated by wounding or light [57]. According to Bejarano et al [55], a significant increase in TGA concentration was observed under drought stress conditions in most potato varieties (average However, one should note that, in 2004, the highest content was as much as 2.60 mg kg −1 FW.…”

Effect of Magnesium Supply and Storage Time on Anti-Nutritive Compounds in Potato Tubers

et al. 2020

The nutritional quality of potato tubers is cultivar-specific and depends on climate-soil conditions and agrotechnical practices, as well as the conditions during long-term storage. Studies were performed from 2009–2011 to determine the effects of magnesium fertilisation and storage duration on the contents of the anti-nutritive compound nitrates, nitrites and total glycoalkaloids (TGA) in potato tubers of mid-early cultivar “Bila” (Solanum tuberosum L.). Magnesium (Mg) was applied in doses of 0, 20, 40, 60, 80 and 100 kg MgO ha−1, respectively, in the form of kieserite–magnesium sulphate (26% MgO). Potato quality after harvest and after three and six months of storage was determined. The content of nitrates in tubers after harvest ranged from 303 to 356 mg kg−1 FW and nitrites from 1.59 to 1.67 mg kg−1 FW. Increasing magnesium fertilisation reduced the nitrate and nitrite content of tubers but increased TGA content. Possible explanations for the TGA increase after Mg supply are discussed. Tubers that contained less TGA after harvest also had less glycoalkaloids after storage. However, physical damage during harvest or transportation, exposure to light and bad storage conditions increase the concentrations of glycoalkaloids in tubers. The consumption of cultivar “Bila” would not exceed the acceptable daily intake of harmful substances.
