“…Crop losses can also be minimized by cultivating potato cultivars that are more resistant to pathogens (Cooke et al 2011). Potato cultivars with colored flesh contain 2 to 10 times more phenolic acids than traditional cultivars with yellow flesh (Brown 2005;Hamouz et al 2010;Ezekiel et al 2013;Bellumori et al 2017), and they are more resistant to stressors, including pathogens (Tierno and Ruiz de Galarreta 2016). Dixon (2001), Mandal et al (2010) and Terry et al (2014) demonstrated that phenolic compounds participate in defense responses in plants exposed to pathogens.…”

The Effect of Growth Regulators and a Biostimulator on the Health Status, Yield and Yield Components of Potatoes (Solanum tuberosum L.)

In this study, the influence of potato cultivars Irga, Satina, Valfi, Blaue St. Galler and Highland Burgundy Red (HB Red), growth regulators: Bio-Algeen S-90, Kelpak SL and Trifender WP, and the biostimulator Asahi SL on the health status of potato plants and tuber yield was investigated. The severity of late blight and early blight was estimated during the growing season. After harvest, potato tuber yield was determined according to size fractions. The applied treatments significantly reduced the severity of late blight in cv. Irga (Kelpak SL), Valfi (Bio-Algeen S-90, Kelpak SL, Trifender WP) and Blaue St. Galler (Trifender WP) in 2013. In 2015, the symptoms of early blight were significantly reduced in cv. Irga after the application of all tested bioregulators. HB Red was characterized by the best health status among the evaluated cultivars. Kelpak SL and BioAlgeen S-90 increased the tuber yield of cvs. Irga and HB Red, respectively, in 2013, and Trifender WP increased the tuber yield of cv. Satina in 2014. In the first year of the study, the applied growth regulators and biostimulator significantly increased the percentage of medium-sized tubers of cv. Blaue St. Galler, and Bio-Algeen S-90 increased the percentage of medium-sized tubers of cv. HB Red.

“…Natural colourant and antioxidant present in purple-and red-flesh potatoes can be used for developing functional foods/nutraceuticals. Considering the large quantities in which potatoes are consumed throughout the world, potatoes could be a very good vehicle for addressing some health related problems [2]. Many of the compounds present in potato are important because of their beneficial effects on health, therefore, are highly desirable in the human diet [3].…”

Abstract-Many of the compounds present in potato are important because of their beneficial effects on health, therefore, are highly desirable in the human diet. The orange and yellow colour of the tuber flesh is due to carotenoids. The aim of this research was to determine the content of total phenolic content and carotenoids in relationship with the colour of organically and conventionally cultivated potato varieties before and after period of storage. In the research 31 potato samples of 12 potato varieties were analyzed on total carotenoid, total phenolic content and colour. Obtained results show that there was significant influence on carotenoid content between different cultivation environments (p<0.05) and between varieties (p<0.05). Total phenolic content significantly varies both per variety (p<0.001) and storage conditions (p<0.001).

“…It relates to the content of anthocyanin pigments that are contained in flesh and skin of pigmented potato cultivars. The concentration and stability of these highly desirable phytochemicals and constituents in diet are effected by several factors such as genotype, agronomic factors, postharvest storage, cooking and processing conditions (Ezekiel et al 2013).…”

In precise field trials in the years 2010 and 2011 the effect of genotype and location in cultivars with yellow, white, purple or red flesh on the content of chlorogenic acid (CA) and in 2011 and 2012 the effect of organic cultivation were evaluated. The results show a statistically significant effect of genotype to CA content, which ranged from 74.0 mg/kg fresh matter (FM) (Agria) to 825 mg/kg FM (Vitelotte). Demonstrable effect of flesh colour on CA content between cultivars with coloured flesh was found (430 mg/kg FM) in comparison with cultivars with yellow or white flesh (71.1 mg/kg FM). For cultivars with coloured flesh rather the genotype specific cultivar ruled than the purple or red flesh colour. In terms of the influence of location, higher CA levels were found on warm locations with frequent periods of drought in comparison with locations of high altitude climatic conditions which are favourable for potato cultivation. In the organically grown potatoes significantly higher levels of CA were found as compared with conventional treatment.
