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. |

Theobroma grandiflorum (cupuassu) is an important fruit tree native to the Brazilian Amazon. Establishing the genetic diversity and structure of populations is critical to define long-term strategies for cupuassu conservation presently threatened by rapid deforestation. Three natural populations collected at the putative center of diversity, three groups of accessions established at a germplasm collection, and one derived from commercial plantings were analyzed. The genetic diversity was assessed using 21 polymorphic microsatellite loci originally developed for Theobroma cacao, disclosing a total of 113 alleles. The estimated genetic diversity parameters averaged over cupuassu populations (A?=?3.53 alleles per locus; H e?=?0.426; H o?=?0.346) were lower than the values reported for other Neotropical tree species. The three natural populations presented a positive and significant fixation index (f), ranging from 0.133 to 0.234. Cupuassu apparently adhered to a general pattern of genetic diversity structure of some Neotropical tree species occurring at low densities, with a low intrapopulation genetic diversity and important levels of endogamy, possibly due to biparental inbreeding derived from the presence of spatial genetic structure in the populations. A high level of genetic divergence was detected among the natural populations (? p?=?0.301), a strong differentiation caused by limited gene flow, and suggesting that human interference in spreading and/or stimulating plantings might have had a smaller effect than expected. The approximate location of the T. grandiflorum center of diversity could not be confirmed by analyzing natural populations from the putative region.
