Full-sib progenies were evaluated with the objective of comparing the performance of selected individuals in progenies tests with their clones in clonal tests. The experiments were carried out in randomized complete block design with five replications, five plants per plot, spaced at 3 m x 3 m, and four controls. The wood volume of each tree was determined after four years of growth. The 173 selected trees in the progeny test were used in the clonal tests in two different locations. The same experimental design was used with 20 replications, one tree plot, spaced at 3.5 m x 2.15 m with a border, and 13 controls (commercial clones). The growth traits of each tree were determined after two years of planting. Genetic parameters were estimated using general linear models. Realized heritability was greater than 80% indicating that the selection of trees in the progeny test was efficient. |

Cratylia argentea is a shrub legume native to tropical regions of South America where it is used for animal feed and green manure. In the absence of germination guidelines, the key aim of this study was to define the most suitable temperature for conducting germination and accelerated aging tests. The biochemical attributes of seeds were also assessed. Seeds with 10 % moisture from 4 different seed lots were germinated using the between paper method in a germinator at temperatures of 20, 25, 30 and 35 °C and alternating temperatures of 20/30 °C (16/8 h), with daily counting until germination was stable (seven days without germination). For the accelerated aging test, two temperatures (41 and 45 °C) and six aging periods (0, 24, 48, 72, 96 and 120 h) for seeds with between 10?40 % moisture content were used. Carbohydrates (%), ethereal extract (%), crude protein (%) and macro and micronutrient contents of the seeds were measured. Results showed that C. argentea seeds consist predominantly of starch (22.67 %) and protein (26.45 %) reserves with a low percentage of lipids. For the germination test, the temperature of 30 °C is recommended, allowing greater percentage and speed of germination, with seedling evaluation at 10 and 20 days. For the accelerated aging test, aging for 48 h at 41 °C is recommended to discriminate C. argentea seed lots in terms of quality. |
