Growth and yield plots have been monitored in the Tapajós region, Pará State, Brazil, since 1981 in four research sites: unlogged primary forest, two areas logged 7 and 13 years before the last assessment, and a secondary forest ca. 50 years old. Diameter increment, mortality and volume increment in these sites are reported. Growth responses were investigated in relation to crown illumination and ecological guild of species. Irrespective of ecological guild, the amount of light received by crowns appeared to produce significant differences in tree growth. A hierarchy of growth rates was observed: rates of diameter increment of intolerant species > tolerant canopy species > understorey tolerant species. Mortality rates were higher for weed species in all study areas except in secondary forest. At this site understorey tolerant species showed higher mortality rates, folio-wed by weed species. Average annual volume increment ranged from 1.6 m' ha-' yr.' in primary unlogged forest to 4.8 m%a-' yr-l in primary logged forest. Commercial species produced just over 1 m3 ha-l yr.' in the logged stands. Establishing cutting cycles in the Tapajós region and other similar sites must have regard to these low increment rates. |

BSTRACT. Brazil is highlighted as the largest producer and consumer of passion fruit (Passiflora) and holder of representative biodiversity. Studies dedicated to the genetic characterization of the genus in order to understand the existing diversity are important for the advancement of genetic improvement and conservation programs. The aim of this study was to select combinations of RGA (Resistance Genes Analogs) primers for commercial passion fruit species and varieties. To this end, amplification tests were performed on a PCR platform in 17 combinations of RGA primers for eight species and 12 commercial varieties of passion fruit from the Banco Ativo de Germoplasma Flor da Paixão. All combinations of primers have generated amplification products in at least one of the Passiflora samples. The number of combinations that generated amplification products varied from seven to 12 in the species and from three to eight in the varieties. Three to 12 combinations generated amplification products for the samples, emphasizing that the RGA markers were efficient in accessing genomic loci in the species and varieties of passion fruit. The variation of efficient combinations in each of the species and varieties attested to the importance of this research in the preliminary stages of genetic studies as auxiliary tools in conservation and genetic improvement programs. However, this study made it possible to identify combinations of primers to be prioritized in inter and intraspecific genetic characterizations of passion fruit MenosBSTRACT.
