“…The mineral composition of both tuber flesh and peel varied widely between locations, which is consistent with previously published data showing that potatoes of the same cultivar grown at different locations contain varying levels of minerals (True et al 1978;Krištůfek et al 2000;Rivero et al 2003;Sterrett et al 2006). Many of these differences in tissue mineral content are reflected in the levels of soil minerals at each location.…”

Zebra chip (ZC) is an emerging and damaging disease of potato (Solanum tuberosum L.) that has been documented in potato fields throughout the southwestern United States, Mexico, Central America, and most recently New Zealand. The bacterium "Candidatus Liberibacter" has been putatively identified as the causal agent of this disease and the potato psyllid, Bactericera cockerelli (Sulc), as the insect vector. Tuber symptoms of ZC-infected plants include collapsed stolons, enlarged lenticels, vascular tissue browning, medullary ray discoloration, and necrotic flecking. ZC tuber symptoms are similar to those of potato diseases which exhibit perturbations in tuber mineral composition resulting in internal necrotic disorders. To determine the effect of ZC disease on the mineral content of potato tubers, concentrations of P, K, S, Ca, Mg, Na, Fe, Al, Mn, Cu, Zn, and B were analyzed in 'Atlantic' potatoes from ZC-infected and free plants, for both tuber flesh and peel tissues. The potatoes were grown at Weslaco, TX and Wapato, WA, two different and distant geographical locations under controlled cage conditions. Results showed that flesh tissue from ZC-infected tubers had significantly higher concentrations of P, K, and Ca at both locations, whereas, ZC-infected tuber flesh from Weslaco had higher concentrations of Mg, Cu, Zn, and B, while concentrations of Fe and Al were higher in ZC-infected tuber flesh from Wapato. Peel tissue from ZC-infected tubers were found to have a significantly higher level of Zn at both locations, whereas the levels of P and Na were found to significantly higher in peel tissue from Wapato and Weslaco, respectively.Finally, Mg was found to be significantly higher in ZC-free tubers from both locations and levels of Cu and B were significantly higher in ZC-free peel tissue from Wapato.Resumen Zebra chip (ZC) es una enfermedad emergente y dañina de papa (Solanum tuberosum L.) que ha sido documentada en campos de papa en todo el sureste de los Estados Unidos, México, Centro América, y recientemente en Nueva Zelandia. Se ha identificado presuntamente a la bacteria "Candidatus liberibacter" como el agente causal de esta enfermedad, y al psílido de la papa Bactericera cockerelli (Sulc) como el insecto vector. Los síntomas del tubérculo de plantas infectadas con ZC incluyen el colapso de los estolones, lenticelas alargadas, oscurecimiento del tejido vascular, coloración radial medular y manchas necróticas. Los síntomas de ZC en tubérculo son similares a los de enfermedades de papa que muestran alteraciones en la composición mineral del tubérculo que resulta en desordenes internos necróticos. A fin de determinar el efecto de la enfermedad ZC en el contenido mineral de tubérculos de papa, se analizaron las concentraciones de P, K, S, Ca, Mg, Na, Fe, Al, Mn, Cu, Zn, y B, en plantas infectadas con ZC y sanas de la variedad Atlantic de papa, tanto de la pulpa como de la cutícula. Las papas se cultivaron en Weslaco, TX y Wapato, WA, dos ubicaciones geográficas diferentes y distantes, bajo condiciones controla...

“…However, elevated Al concentrations (>7-16 mg kg −1 ), which most likely indicate contamination from soil were observed in the same samples. Previous reports of dramatically high Fe concentrations in unpeeled potatoes (115 mg kg −1 on a DW basis) 7 along with high Al levels (75 mg kg −1 on DW basis) suggest possible contamination of samples with soil particles. Fe from soil is poorly soluble in gastric juices and hence its bioavailability is expected to be poor.…”

“…Potatoes are an important source of different dietary minerals. Potato is listed as providing 18% of the Reference Daily Intake (RDA) of potassium, phosphorus and magnesium, and 2% calcium and zinc (True et al, 1979). Potatoes rank highest for K content among 20 most frequently consumed cereals including rice and wheat, raw vegetables and fruits.…”

“…Potato is listed as providing 18% of the RDA of K, 6% of Fe, P and Mg, and 2% Ca and Zn (True et al, 1979). There are significant differences in major and trace mineral contents amongst different genotypes of potato (True et al, 1978). Potassium levels varied the most and manganese the least (Andre et al, 2007).…”

Twenty two potato accessions from USA were evaluated for nutrient contents. Two Bangladeshi varieties were also included for comparison. Nutritional analyses were performed in the Department of Agricultural Chemistry, BAU during November, 2014 to April, 2015. Considering macro nutrient content, the highest values of N, P, K and S were found in the accession AC 10062 whereas Ca and Mg contents were found highest in Bangladeshi variety Cardinal and USA accessions AC 10073, respectively. In case of micro nutrient, the maximum amounts of Cu, Mn, B and Zn were observed in accession AC 10110, AC 10069, AC 10073 and AC 10109, respectively. Significant positive correlations were observed between N-P, N-K and K-Mn contents while K-Mg, Mn-B and Cu-B contents were negatively correlated. Considering all the parameters studied, the USA accession AC 10062, AC 10069 and AC 10110 were nutritionally superior to Bangladeshi variety Diamant and Cardinal. The accession AC 10062 was found as the best USA accession to produce nutrient rich potato in Bangladesh.J. Bangladesh Agril. Univ. 13(2): 207-214, December 2015
