“…Two of the analyzed potato cultivars, Irga (cream-colored flesh) and Satina (yellowcolored flesh), are registered on the Polish National List of Agricultural Plant Varieties, and three cultivars, Valfi, Blaue St. Galler (blue-purple-colored flesh) and Highland Burgundy Red-HB Red (red-colored flesh), are listed in the European Common Catalogue of Varieties of Agricultural Plant Species. The soil, climate and agronomic conditions of the experiment have been described elsewhere (Głosek-Sobieraj et al 2018). Seed potatoes were planted in heated soil, 40 cm apart, with inter-row spacing of 67.5 cm.…”

The aim of this study was to evaluate the influence of cultivar and biostimulants on the health status of potato tubers after harvest and after 5 months of storage. The fungal pathogens isolated from potato tuber were cultured on PDA. The biostimulants limited the symptoms of dry rot in cv. Satina after harvest, in stored cv. Irga (Bio-Algeen S-90) and cv. Blaue St. Galler (Kelpak SL). The symptoms of common scab were reduced in stored potatoes cv. Satina in the Asahi SL treatment and the symptoms of late blight in stored potatoes cv. Satina in the Kelpak SL and Trifender WP treatment and in cv. Valfi in the Bio-Algeen S-90 and Kelpak SL treatment. Asahi SL and Kelpak SL decreased the severity of black scurf in stored potatoes cv. Irga. Biostimulants decreased the occurrence frequency of the causative agents of dry rot and black scurf after harvest. Total chlorogenic acid, which is predominant in potato tubers, was present in higher concentrations in the skin than in the flesh. Potato tubers had the highest content of 5-caffeoylquinic acid, followed by neochlorogenic acid (3-caffeoylquinic acid) and cryptochlorogenic acid (4-caffeoylquinic acid). Higher concentrations of chlorogenic acid were found in potato cultivars with blue-purple-and red-colored flesh than in those with yellow-and cream-colored flesh, and in response to the application of the Asahi SL biostimulant and Trifender WP.

“…In the current experiment, the content of the analyzed chlorogenic acids increased in response to inoculation with P. infestans in both the control treatment and the treatment with Trifender WP; were higher in wet years of 2013 and 2014 (weather conditions were conducive to the infections by pathogen) than in the dry year of 2015 [Głosek--Sobieraj et al 2018]. The strongest correlation between the analyzed factors was observed in the first year of the study (r = 0.31 in the control treatment and r = 0.35 in the treatment with Trifender WP) (Fig.…”

Five potato cultivars were grown in a micro-plot field experiment (under conditions of natural infection by pathogens). In experimental treatments, potatoes were treated with Trifender WP, whereas control plants were not treated with growth regulators. A greenhouse experiment, conducted simultaneously, involved three treatments: 1. control (no biostimulant treatment, no inoculation), 2. inoculation (potato plants inoculated with P. infestans), 3. Trifender WP+inoculation (soil and foliar application of Trifender WP followed by inoculation with the pathogen 2 days after the last treatment). The research material was potato petioles, in which changes in the concentration of analyzed chlorogenic acids were determined using the Waters Acquity UPLC technique. In comparison with the control treatment, higher concentrations of the 5-caffeoylquinic acid (5-CQA), 4-caffeoylquinic acid (4-CQA) and 3‑caffeoylquinic acid (3-CQA) were found in potatoes treated with Trifender WP, and in cultivars with blue-purple and red-colored flesh than in those with yellow and cream-colored flesh (field experiment). In the greenhouse experiment, the content of individual chlorogenic acids increased in the petioles of potatoes inoculated with P. infestans and inoculated with the pathogen after the application of Trifender WP, compared with the control treatment

“…Potatoes were planted by 23 to 30 April, and were harvested by 26 to 28 August. Pathogens and pests were controlled chemically, and weeds mechanically [23]. The tubers (35-50 mm, after harvest and 5 months of storage) were peeled (skin thickness 3-4 mm) and cubed.…”

The nutritional value of agricultural crops has to be closely monitored due to the continued decrease in the concentrations of minerals in fruit and vegetables in recent decades [1]. Potato tubers are a rich source of nutrients in the human diet, including protein, carbohydrates, fiber, antioxidants (vitamin C, phenols, anthocyanins), and minerals (1-2%) [2][3]. Ratios between minerals are of particular importance to human health [4]. The growing demand for potatoes with high nutritional value necessitates research into new varieties and production technologies. Potato cultivars with colored skin and flesh are becoming increasingly popular due to their superior nutritional value relative to
