| The growth of plant species can be affected by waterlogging. This process occurs as result of physiological changes that occur at the plants. The study aimed to comparatively evaluate the growth and expression of seed vigor of common bean genotypes subjected to soil waterlogging. For each of the genotypes IPR Tuiuiú and Carioca, treatments consisted of combining soil waterlogging for 12 hours or kept at field capacity, and plant sample collection times. Plant samples were collected at every 20 day intervals, being determined dry mass, leaf area and seed vigor. The plants of genotype IPR Tuiuiú showed higher growth and similar expression of seed vigor under soil field capacity. In plants of genotype Carioca, soil waterlogging did not affect growth and... |

| The soil waterlogging reduces oxygen content near the roots, affecting energy metabolism and absorption of water and nutrients. Thus, the objective of this study was to evaluate the effect of different periods of soil waterlogging on physiological characteristics of initial growth in oat plants. The treatments consisted of soil in field capacity and soil flooding for 72 and 120 hours, with six replications. To analyze the initial growth were observed the number of leaves, leaf area, leaf area ratio and leaf weight, specific leaf area, dry weight of leaf, stem and roots, length of shoot and primary root. The increasing of the period of flooding reduced the accumulation of root dry matter, the leaf area and the specific leaf area. However, the length of... |
