Physico‐mechanical seed properties of the common Turkish bean (Phaseolus vulgaris) cultivars ‘Hinis’ and ‘Ispir’

Abstract

41Physico-mechanical seed properties of the common Turkish bean (Phaseolus vulgaris) for 'Hinis' and 'Ispir', respectively. The average 1000 seed weight, bulk density, and porosity were determined as: 531.3 and 598.9 g, 835.8 and 872.7 kg m -3 , and 34.0% and 33.1% for 'Hinis' and 'Ispir', respectively. The average angle of repose and terminal velocity were 24.52° and 19.46°, and 11.42 and 11.80 m s -1 in 'Hinis' and 'Ispir' respectively. The highest coefficient of dynamic friction was obtained with an aluminium surface in both cultivars as 0.227 for 'Hinis' and 0.199 for 'Ispir'. This was followed by fibreglass, steel, plywood, and glass surfaces. Both cultivars had white testae. The average value of rupture force, deformation at rupture point, energy absorbed, hardness, and toughness along the

Physical and cooking characteristics of some Indian kidney bean ( Phaseolus vulgaris L . ) cultivars

“…Lowest porosity was reported for Local Red cultivar. Porosity of different kidney bean cultivars has been reported in the range of 33.05-40.43% (Ozturk et al, 2010(Ozturk et al, , 2009. So, our results fall within the range reported by these authors.…”

“…Local Red had the lowest seed volume and surface area while as it was the highest for Master Bean. The values reported here are lower than reported elsewhere (Ozturk et al, 2010;Altuntas and Demirtola, 2007;Ozturk et al, 2009). This might be attributed to smaller size of kidney beans cultivars used in this study than those studied by these authors.…”

“…Significant differences were observed in bulk density and true density in the range of 0.78-0.81 kg/L and 1.22-1.27 kg/L, respectively (Table 2). Bulk density and true density of kidney bean cultivars in the range of 0.72-0.87 and 1.23-1.31 kg/L, respectively has been reported (Ozturk et al, 2010(Ozturk et al, , 2009.…”

“…Color values of kidney bean cultivars revealed significant (p 6 0.05) differences ( (Ozturk et al, 2010(Ozturk et al, , 2009). The differences in reported and observed values might be attributed to the genetic differences.…”

“…Lowest angle of repose was reported in Master Bean and highest in French Yellow. Angle of repose for different kidney bean cultivars has been reported to vary between 11.66°and 29.62° (Ozturk et al, 2010(Ozturk et al, , 2009Altuntas and Demirtola, 2007).…”
