Myrcia lundiana Kiaersk. is a tree of the family Myrtaceae found in tropical and subtropical areas southern hemisphere that produces essential oil.The aim this study was to characterize genetic diversity M. plants from native population Parque Nacional de Itabaiana, using inter-simple sequence repeat molecular markers.Thirty-five primers were tested, 20 which polymorphic, resulting 135 polymorphic informative bands.Results cluster analysis, obtained unweighted pair group method with...

Abstract: For native species in Brazil, there is a great need for scientific information that allows efficient production and storage of seeds. The present work evaluated the physiological molecular changes Hancornia speciosa seeds stored conservative solutions. experiment was carried out completely randomized design, split-plot scheme, with eight replications. In plots, solutions (A, B, C, D) were allocated, subplots periods (50, 100, 150, 200 days). following variables analyzed: water...

ABSTRACT Basil is an aromatic herb that stands out for its economic importance. It consumed in natura and used to obtain essential oil. The cultivation of this species several regions the world has allowed variations by natural crosses euploidy, leading wide genetic variability found nowadays. Considering importance species, we aimed analyze diversity 27 basil genotypes using ISSR molecular markers. Fourteen primers were employed DNA amplification, resulting 86% polymorphism. Based on...

Hyptis pectinata, popularly known as 'sambacaitá' or 'canudinho', is a medicinal and aromatic species widely used in the Brazilian Northeast. In Sergipe, excessive extraction of natural resources may reduce genetic variability native plants. Thus, molecular markers have frequently been applied to characterization diversity basis for germplasm conservation breeding programs.
