| The wall perimeter fraction, which contact neighboring cells, was named compression ratio (alpha). A zero compression ratio indicates maximum intercellular (air) volume (vG, v/v) and neglectable contact among cells, while alpha=1 indicates complete adherence between neighboring cells and no vG in the lattice. The maximum intercellular air volume (beta, v/v), when alpha=0, was 0.593 for triangular, 0.2146 for square and 0,0931 for hexagonal lattices. The equation alpha=1- (vG/beta)½ was derived to relate alpha, beta and vG in the studied lattices. The relation (P S=p/alpha) between cell turgor (P S) and the tissue aggregating pressure (p), defined as the compression to keep in place a layer of cells, was demonstrated using the compression ratio concept.... |

| ABSTRACT Production of purple-fleshed sweetpotatoes, source of anthocyanins, pigments with high antioxidant activities, is expected to be extended during the upcoming years, as there is a strong trend to market products promising improved health. This study aimed to evaluate yield, postharvest quality and pest resistance of roots of purple-fleshed sweetpotatoes. Six genotypes (BGBD 0005, BGBD 0080, BGBD 1261, BGBD 1399, BGBD 1402 and BGBD 1405) and the cultivars Beauregard and Brazlândia Roxa as controls were evaluated during two seasons 2018 (Experiment 1) and 2019 (Experiment 2), in Brasília-DF, Brazil. The experiments were conducted in a complete randomized blocks design with four replications, with experimental plots consisting of two rows of six... |
