To meet the demands of the production chain, breeding programs need to reduce the time for selection and development of higher yielding maize genotypes. This involves application of new strategies, such as the use of the doubled haploid lines. We evaluated the use of stomatal area and density in distinguishing doubled haploids (DH) from false positive (FP) plants derived from nine tropical source populations. We selected four DH plants and two FP plants for identification of DH through leaf anatomy in the populations, in each group. Data on stomatal area and density were considered in a completely randomized model in a factorial scheme (populations and genotypes) and analyzed by restricted maximum likelihood. There were statistically significant effects of populations and genotypes for both traits. For stomatal density, the population by genotype interaction was not verified. Stomatal density proved to be efficient for distinguishing DH and FP for use in selection of doubled haploids. |

The quality attributes of Italian tomato fruit produced in organic and conven-tional systems, and packed and stored at room temperature (24±2.0°C and 32±2% RH) or cool conditions (12±1°C and 73±1% RH) for 20 days were determined. Color, firmness, titratable acidity, total soluble solids, vitamin C, lycopene, ? carotene, total phenolics and total antioxidant activity were evaluated. Concentrations of lycopene, ? carotene, vitamin C, acidity, phenolics and antioxidant activity were influenced by the cropping system, and time and temperature of storage. Fruit produced organically had higher concentrations of vitamin C throughout storage as well as higher soluble solids at 0, 10 and 20 days, and higher antioxidant activity at 0, 5 and 10 days than conventional fruit regardless of storage temperature. Fruit from the conventional cropping system had higher acidity than organically produced fruit at 5 and 15 days of room and cool storage. At 10, 15 and 20 days, there were no differences in lycopene concentrations of tomatoes between cropping systems. |
