“…3). This result was higher than that observed by Franzon & Raseira (2004), who obtained values of 35.3% and 33.5%, respectively, in two accessions of Surinam cherry. The results obtained in this study are also higher than those obtained by Franzon et al (2007), who analyzed the in vitro germination capacity of Surinam cherry pollen using various types of culture and obtained germination results below 30%.…”

“…Several types of molecular markers have been used for the analysis of genetic diversity in different species, but there are few records for native species of the South of Brazil (Franzon & Raseira 2004), mainly species of the Myrtaceae family; which may be associated with the presence of polyphenols that hinder DNA extraction (Almeida et al 2012). In this study, RAPD markers were used because it is a simple, fast, and relatively inexpensive technique with informative potential, although it presents repeatability problems (Areias et al 2006).…”

Surinam cherry (Eugenia uniflora L.) is a fruit species with the potential for economic exploration. The objective of this study was to evaluate the genetic variability and cytological stability in 40 accessions of Surinam cherry in the State of Rio Grande do Sul. We used 18 molecular markers of RAPD (Random Amplified Polymorphic DNA) to access the genetic variability. The cytological analysis included meiotic behavior, viability, and in vitro germination of pollen and counting the anthers number. The analysis of genetic variability allowed the separation of the accessions into three groups with an average of 9.5 bands amplified by the primer; 8.39 polymorphic bands; 88.57% of polymorphism and 86% genetic similarity. In the cytological analysis, the average normal meiotic cells were 85.07%; average pollen viability was 90.47%; in vitro germination of 44.33%; and the anther/flower average of 54.53. Therefore, the accessions have high genetic similarity and cytological stability.

“…Costa and ForniMartins (2006a) evaluated the meiosis and pollen viability of four species of the Campomanesia and Psidum genus and did not observe any abnormalities and also identified a pollen viability higher than 86%. Franzon and Raseira (2004) observed cytological stability higher than 96% in Acca sellowiana, while in Eugenia pyriformis and Campomanesia xanthocarpa the stability was 89.5% and 89.3%, respectively.…”

“…Franzon and Raseira (2004) and Franzon et al (2007) evaluated the germination capacity of cherry tree pollen and found values higher than 60%. These results may be associated with the methodology since, according to Marcellán and Camadro (1996), many factors can influence germination, such as: culture medium, incubation temperature and length.…”

Myrtaceae are one of the largest families of flowering plants and are widely distributed in the Neotropics, where they are mainly represented by the tribe Myrteae. Myrteae are the most species-rich tribe of Myrtaceae and include groups with significant ecological and economic importance. Myrteae are considered to be a model group for biodiversity studies in the Neotropics, and so understanding the history of their diversification in this area is extremely important. The last decade has witnessed an increase in macro- and microevolutionary studies of the group, and summarizing this knowledge is now crucial to plan future steps in research on Myrteae. Here we provide the first overview of evolution and diversification studies on Myrteae, highlighting recent advances in understanding their evolutionary history. We discuss biogeography, phylogeny, phylogeography, population genetics, genomics and cytology in light of current knowledge. Finally, we provide perspectives and open hypotheses to be tested in future studies to fill gaps in the evolutionary knowledge of specific groups/taxa in Myrteae.
