Abstract: A field experiment was conducted to evaluate the effects of planting different sizes of seed of the same cultivar on biomass accumulation and grain yield of common bean (Phaseolus vulgaris L.) cultivars of different seed sizes. A 6 X 2 split-plot factorial design with four replicates was employed, with six bean cultivars as main plots and two seed sizes (small and large, the latter twice as heavy as the former) of the same cultivar as subplots. Eight weekly samplings of biomass were performed, and yield compon… Show more

“…According to the results obtained in this last study, larger seeds present higher germination and vigor, produce taller plants, which have higher productivity at harvest. Moreover, standardization by seed size is relevant to accuracy of mechanical sowing (Krzyzanowski et al, 1991), as well as to improve visual and commercial aspect of the seed lots (Lima and Carmona, 1999).…”

“…Even in the growth stages of increasing number of live leaves, between 34 and 48 DAE (Figure 1), leaf decay was already going on (Figure 2). Under field conditions, the maximal leaf area index of cultivar Carioca was observed at 40 DAE (Lima et al, 2005). This denotes that the maximum production of biomass of a common bean plant can not be defined only by the standing shoot biomass, since even in the stages of intense growth there is a loss of leaf mass Table 1.…”

“…(2005) destacan como características adicionales de alta calidad de germinación y que se presenta a menudo, excepto cuando se siembran semillas extremamente grandes (Jansen et al, 1998). Resultados similares encontraron Lima et al (2005) en semillas más grandes de frijol común (Phaseolus vulgaris L.), las cuales fomentaron la biomasa de la parte aérea y subterránea de la planta y el índice de área foliar, comparado con las más livianas, especialmente en el crecimiento inicial de la planta; estos autores recomendaron el uso de semillas más pesadas para favorecer el establecimiento de cultivos en sitios con condiciones de estrés. Volumen de raíz El embrión de la semilla contiene la radícula o meristemo radical, del cual se desarrolla la raíz pivotante (Kozlowski y Pallardi, 1997).…”
