Variability of mass and content of mineral elements in grains of the common bean cultivar Pérola

Abstract

The cultivar Pérola is the most widely bean cultivar cropped. In the market, it is a reference in grain size, which is related to its mass, which, in turn, is influenced by the growing conditions. The objective was to quantify the 100-grain mass and the contents of mineral elements in the common bean cultivar Pérola, coming from the municipality of Cristalina, Goiás. It was selected 18 different areas in the city, under center pivot irrigation, where 86 samples of grains were collected during the crop harvest. The data were submitted to univariate statistical analysis, calculating maximum and minimum values, averages, amplitude of variation and coefficients of variation. It was determined the values of Pearson correlation between the contents of mineral elements in the grains. The 100-grain mass had wide range of values, from 17.30 to 33.50 grams. The composition of minerals in beans was, in descending order, N, K,

Relationship between origin and nutrient content of Croatian common bean landraces

“…Trešnjevac', 'Zelenčec' and 'Puter'). Obtained total nitrogen values were similar to or slightly higher compared to data reported by Bevilaqua and Antunes (2015), Barros and Prudencio (2016) and Silveira et al (2016)…”

“…Both mentioned landraces are from Andean gene pool which indicates high variability in Mn content among landraces of the same gene pool. Determined values were similar or higher to those reported by other authors (Bevilaqua and Antunes, 2015;Barros and Prudencio, 2016;Silveira et al, 2016), except Moraghan and Grafton (2001) who reported 16-27 mg Mn•kg -1 DW.…”

“…Gouveia et al (2014) reported higher content of potassium in common bean seed, up to 2.49% K DW. Other authors (Bevilaqua and Antunes, 2015;Barros and Prudencio, 2016;Silveira et al, 2016) reported similar or lower values compared to K content determined in the present research.…”

“…Magnesium content varied from 0.17 to 0.2% DW, with the average of 0.18% Mg DW ± 0.03 SD. All reported data compared on dry-weight basis were higher or similar to values reported by Moraghan and Grafton (1997;), Gouveira et al (2014 and Silveira et al (2016).…”

“…Trešnjevac') determined P content was significantly lower compared to landraces of Mesoamerican gene pool ('Tetovac', 'Kukuruzar' and 'Biser'). Phosphorus content values in dry bean seeds reported by Gouveia et al (2014) and Bevilaqua and Antunes (2015) (0.63 and 0.75% P DW, respectively) were higher compared to present results, whereas other authors reported lower values (Beebe et al, 2000;Barros and Prudencio, 2016;Silveira et al, 2016). Phosphorus is an important mineral for plant metabolism and in seeds is present as constituent of nucleic (Bergman, 1992) and phytic acid (Guzman-Maldonado et al, 2000).…”
