The aim of the laboratory experiment was the isolation of fungi colonized potato tubers directly (immediately) after harvest and after 5-month storage. 67 potato tubers samples collected in 1998 and 1999 from the areas of province Warmia and Mazury were examined. The occurrence of 36 and 46 species were confirmed on analyzed tubers after harvest and storage, respectively. The most frequent species which occurred on tubers were: <i>Alternaria alternata</i> (9,4%), <i>Colletotrichum cocco- des</i> (12,6%), <i>Rhizoctonia solani</i> (7,4%) and fungi from <i>Fusarium genera</i> (8,7%).This fungi, except <i>Rhizoctonia solani</i>, more often colonized potato tubers afier storage. Among saprofitic fungi most frequent were: <i>Epicoccum</i> (3,4%), <i>Mortierella</i> (3,1%), <i>Mucor</i>(6,0%), <i>Penicillium</i> (17,0%), <i>Rhizopus</i> (7,1%) and <i>Trichoderma</i> (12,9%). More colonies of fungi were obtained from potato tubers analyzed after harvest. Remaining fungi were more frequently isolated after storage.

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.

Abstract This study was carried out in two seasons (2010–2011 and 2012–2013) in Jos, Plateau State, Nigeria to investigate the growth and yield of potato (Solanum tuberosum L.) seed tubers as affected by storage conditions and storage duration. Five potato varieties (“Nicola,” “Bertita,” “Diamant,” “BR63-18,” and “Roslin-Ruaka”) were stored for three durations (12, 24, and 32 weeks) in three kinds of stores (room temperature store [RTS], diffused light store [DLS], and air-conditioned store [ACS]). The experimental design was a split–split plot in a randomized complete block design with the potato varieties, storage conditions, and storage durations as the main, sub, and sub–sub plots, respectively. All the parameters assessed varied with variety except the plant height. Germination and establishment were significantly higher in ACS than in RTS and DLS. RTS and DLS resulted in more aboveground stems than ACS. Storage in ACS resulted in a significantly higher plant height, leaf number, total number and yield of tubers, and yield of saleable tubers in both seasons. Seed tubers stored for 24 weeks resulted in the highest establishment count and the mean number of aboveground stems in both seasons. Aboveground stems increased from 12 to 24 weeks of storage and declined at 32 weeks. Seed storage for 12 weeks resulted in the highest total number of tubers, whereas 32 weeks had the lowest number of tubers in both seasons. Seed storage for 12 and 32 weeks resulted in the highest yield of tubers in seasons 1 and 2, respectively. In conclusion, potato varieties varied greatly in the rate of physiological aging; hence, every variety required specific storage conditions and duration for optimal growth and yield.
