Este estudo aborda aspectos ecologicos de germinacao de sementes de Piptadenia gonoacantha sob inundacao. A germinacao de P. gonoacantha foi avaliada em dois experimentos, germinacao durante submersao e apos diferentes periodos de submersao (5,15 e 25 dias). O primeiro experimento contou com tres tratamentos: papel de filtro umedecido (controle), areia saturada e areia inundada. Em papel de filtro e areia saturada, a porcentagem de germinacao foi alta, 89% e 79%, respectivamente, nao diferindo significativamente entre si. Embora 38% das sementes submersas tenham apresentado protusao da radicula, todas estavam mortas apos nove dias de inundacao. No segundo experimento, a porcentagem de germinacao das sementes submersas por cinco dias foi 70% diferindo significativamente do controle que atingiu 86%. A submersao por 15 dias promoveu perda total de germinabilidade enquanto a porcentagem de germinacao do controle foi 64%. Apesar da baixa capacidade de germinar em condicoes submersas, o crescimento inicial rapido e a epoca dos eventos fenologicos reprodutivos podem favorecer a regeneracao de populacoes naturais de Piptadenia gonoacantha em areas sazonalmente inundaveis. |

Coffee is one of the most important beverages and trade products in the world. Among the multiple research initiatives focused on coffee sustainability, plant breeding provides the best means to increase phenotypic performance and release cultivars that could meet market demands. Since coffee is well adapted to a diversity of tropical environments, an important question for those confronting the problem of evaluating phenotypic performance is the relevance of genotype-by-environment interaction. As a perennial crop with a long juvenile phase, coffee is subjected to significant temporal and spatial variations. Such facts not only hinder the selection of promising materials but also cause a majority of complaints among growers. In this study, we hypothesized that trait stability in coffee is genetically controlled and therefore is predictable using molecular information. To test it, we used genome-based methods to predict stability metrics computed with the primary goal of selecting coffee genotypes that combine high phenotypic performance and stability for target environments. Using 2 populations of Coffea canephora, evaluated across multiple years and locations, our contribution is 3-fold: (1) first, we demonstrated that the number of harvest evaluations may be reduced leading to accelerated implementation of molecular breeding; (2) we showed that stability metrics are predictable; and finally, (3) both stable and high-performance genotypes can be simultaneously predicted and selected. While this research was carried out on representative environments for coffee production with substantial crossover in genotypic ranking, we anticipate that genomic prediction can be an efficient tool to select coffee genotypes that combine high performance and stability across years and the target locations here evaluated.
