    The search for highly productive and adapted genotypes for each producing region has driven the work of characterization and selection of superior and divergent genotypes. Understanding the genetic diversity in Coffea canephora, using the information obtained can favor the best reproductive management of crops, in addition to assisting breeding programs. Thus, considering the economic importance of the crop, the objective was to evaluate the genetic diversity of C. canephora based on nutritional characteristics for the first study and floral characteristics for the second. The first study, entitled “Genetic diversity in C. canephora genotypes for leaf nutrient concentration”, aimed to evaluate the leaf nutrient concentration in coffee genotypes in the pre-flowering and filling of coffee beans. The second, entitled "Genetic diversity in C. canephora based on floral morphological characteristics", aimed to evaluate the genetic diversity existing in Conilon coffee genotypes based on floral morphological characteristics. For both studies, multivariate analysis was performed, and it was found that there is genetic diversity among C. Canephora genotypes based on leaf nutrient concentration, as well as for floral morphological characteristics. Adopting a maximum limit of 60% of dissimilarity between the genotypes, the formation of four and three groups was observed by the UPGMA method for the foliar concentration of nutrients and floral morphological characteristics, respectively. Based on the results obtained and the information generated, the studies can serve as a basis for helping nutritional management and understanding the process of cross-pollination and reproduction of C. canephora. Also, assist in the use of genetic resources of interest in genetic improvement programs.

    Minienxertia de Passiflora edulis Sims f. flavicarpa Deg. em porta-enxertos clonais de Passiflora mucronata Lam. : aspectos morfo-histológicos
    (Universidade Federal do Espírito Santo, 2016-09-02) Oliari, Layane Segantini; Alexandre, Rodrigo Sobreira; Schmildt, Edilson Romais; Aoyama, Elisa Mitsuko; Schmildt, Omar
    Brazil is the largest producer of passion fruit, with 838,244 tonnes achieved in 2013 in an area of 57,277 hectares (IBGE, 2013), and the yellow passionflower (Passiflora edulis f. flavicarpa) the most cultivated. However this species is affected by the ground fungus Fusarium oxysporum f. sp. passiflorae causing the total withering of the plants. Among the alternatives to be sought, there is the use of wild species, resistant to certain diseases, such as rootstock. In this sense, P. mucronata species becomes an option as the rootstock yellow passionflower to be resistant to the fungus causing this disease. This study aimed to evaluate histological aspects of grafting region and morphological of grafted seedlings of apexes of shoots of P. edulis f. flavicarpa on P. mucronata using the mini-grafting technique proposed by Alexandre et al. (2013), by grafting mode on top in full and simple english. The characteristics evaluated were: attachment (%), diameter of the graft (GD), diameter of the rootstock (RD), callus formation, starch into the tissue of the graft and rootstock and the influence of fastening material and emerged side shoots of the rootstock, 21 days after mini-grafting. Also anatomy grafting slit 60 days after implementation of mini-grafting was observed. It was found that the Parafilm® tape provides greater percentage of attachment, in the presence of starch graft reserve parenchyma. The cells that have undergone mitosis is of primary graft parenchymal, this being a younger tissue, cells possess their greatest division rate and the modality top wedg is more simple and practical to implement the mini-grafting P. edulis f. flavicarpa on P. mucronata.
