Elephant grass is a forage plant widely spread in Brazil that was initially employed exclusively in the livestock sector as feed for cattle. This grass is characterized by its high productivity and high photosynthetic capacity. In addition to being used as forage, it has shown to be an alternative source of renewable energy. The objectives of the present study were to evaluate the morpho-agronomic traits of elephant grass hybrids and their parents for biomass energy production. The experiment was conducted in a randomized-block design with three replicates. The partial diallel was composed of 16 hybrids and two groups (males and females). Data were subjected to analysis of variance and the Tukey?s mean comparison test (P < 0.05). Interaction was detected by the F test for the traits dry matter yield, plant height, and leaf width. Based on the mean values, hybrids H11 and H14 seem to be promising for dry matter production for energy purposes. Parent Porto Rico 534-B can be indicated in breeding programs. |

The aim of this research was to study the influence of training system and rootstock on the yield, vigor and physiology of the ?Chenin Blanc? grapevine at São Francisco Valley, northeastern Brazil. An experiment was carried out on eight harvests, from 2013 to 2017, in Petrolina, in the state of Pernambuco. Grapevines were grown under two training systems, lyre and espalier, and five rootstocks: ?IAC 572?, ?IAC 313?, ?IAC 766?, ?Paulsen 1103? and ?SO4?, using a split-plot randomized block design, with training systems assigned to the main plot and the rootstock assigned to the subplot. Lyre favored an increase in the number of bunches, branches and leaf mass in the harvest of the first semester of the year, while in the second semester there were increases of 40 % in the number of bunches and 10 % in leaf mass. Lyre promoted more balanced vines, showing a better ratio between production and pruning weight (Ravaz index). The rootstocks ?IAC 766?, ?IAC 313? and ?IAC 572? increased yield and bunch mass under both training systems, while ?SO4? reduced yield and vigor. The stomatal conductance and instantaneous efficiency of water use were not influenced by either the training system or the rootstock. Under tropical conditions in the São Francisco Valley, ?Chenin Blanc? grapevine may be grown under the lyre training system, preferably on the ?IAC 766? rootstock, to obtain high yields and balanced grapevines. |
