Garcinia brasiliensis (Mart.) is a native Amazonian tree cultivated throughout Brazil. This plant can tolerate flooding or submergence for several days, during certain periods of the year. The morphophysiological changes of G. brasiliensis (Mart.) seedlings were assessed that may favor their survival in flooded environments. Seedlings with six fully expanded leaves were placed in tanks so that their roots were submerged for 90 days. Antioxidant enzymatic activity and the contents of H2O2, soluble sugar, starch, and amino acid of the roots were evaluated on six harvesting occasions. At the end of the experiment, the dry mass and root morphology of the seedlings were determined. Flooding lead to a decrease in dry mass of roots and aboveground parts, as well as root length (58%), surface area (51%) and volume (43%), especially of roots with smaller diameter. The roots of the flooded seedlings presented thicker exodermis and greater xylem number, thicker phloem and fewer xylem fibers. There was a small amount of aerenchyma in the roots and hypertrophied lenticels were detected at the base of the stem. Superoxide dismutase activity was significantly higher in flooded roots at all harvesting times, and ascorbate peroxidase and catalase activities were highest during the last two harvestings. H2O2 content increased after 40 and 55 days of flooding, followed by a drastic decrease. After 70 and 90 days of flooding there was an expressive increase in soluble sugars, and at 90 days, a reduction in starch content. No differences were observed in amino acid content.

This work evaluated the initial performance and genetic diversity of Coffea canephora genotypes cultivated in environments at contrasting altitudes. Fourteen morphophysiological traits and seven descriptors of the genus Coffea spp. of coffee trees cultivated at altitudes of 140 m and 700 m were evaluated. The design used was Federer?s augmented block in a 2 Ã?â?? 112 factorial scheme with six blocks. The first factor was the two environments, and the second was the 112 genotypes, with eight common treatments, being five conilon coffee clones and three arabica coffee cultivars. The data were analyzed by the method of REML/BLUP and genetic correlation method. Genetic diversity was evaluated by estimating the distance matrix, applying the Gower methodology followed by the clustering method by Tocher and UPGMA. The phenotypic means were higher in the environment at an altitude of 700 m, except for plant height, number of leaves, and canopy height (CH). Genotypic effects were significant for most traits except for leaf width, CH, unit leaf area, and total leaf area. A wide genetic diversity was verified, with distances varying from 0.037 to 0.593 for the pairs of genotypes 26 Ã?â?? 93 and T7 Ã?â?? 76, respectively. Most of the traits studied showed high genotypic correlation with the environment and expressive genetic correlation between the evaluated traits thereby demonstrating the possibility of indirect selection. There is an adaptation of conilon coffee genotypes to high altitudes and the possibility of developing a specific cultivar for the southern state of EspÃ?ÂÂrito Santo.
Este trabalho avaliou o desempenho inicial e a diversidade genÃ?©tica de genÃ?³tipos de Coffea canephora cultivados em ambientes em altitudes contrastantes. Quatorze caracterÃ?ÂÂsticas morfofisiolÃ?³gicas e sete descritores do gÃ?ªnero Coffea spp. foram avaliados cafeeiros cultivados nas altitudes de 140 m e 700 m. O delineamento utilizado foi o bloco aumentado de Federer em esquema fatorial 2 Ã?â?? 112 com seis blocos.

A diversidade genÃ?©tica foi avaliada estimando a matriz de distÃ?¢ncia, aplicando a metodologia de Gower seguida do mÃ?©todo de agrupamento de Tocher e UPGMA. As mÃ?©dias fenotÃ?ÂÂpicas foram maiores no ambiente a 700 m de altitude, exceto para altura de planta, nÃ?ºmero de folhas e altura de copa (CH). Os efeitos genotÃ?ÂÂpicos foram significativos para a maioria das caracterÃ?ÂÂsticas, exceto para largura foliar, CH, Ã?¡rea foliar unitÃ?¡ria e Ã?¡rea foliar total. Foi verificada ampla diversidade genÃ?©tica, com distÃ?¢ncias variando de 0,037 a 0,593 para os pares dos genÃ?³tipos 26 Ã?â?? 93 e T7 Ã?â?? 76, respectivamente.
