With the aim of evaluating Eucalyptus spp. for early selection efficiency, the height (HGT), diameter at breast height (DBH) and individual wood volume (VOL) of two clonal tests were assessed at the ages of 25, 50, and 72 ...

The objective of this work was to select adequate early-maturing sweet orange cultivars for the fresh fruit market and for industrial processing using performance indexes. Performance indexes for citrus were established ...

One of the difficulties faced in forest tree improvement programs is the length of the cycle required for genetic selection of superior material in quality and productivity; a problem that can be solved through early ...

In a field trial involving 68 rubber tree (Hevea spp.) clones calculation of genotypic correlation coefficients revealed significant age-age correlation from age 1 to 6 (immature period) for girth A and for age 7 to 12 ...

In a field trial involving 68 rubber tree (Hevea spp.) clones calculation of genotypic correlation coefficients revealed significant age-age correlation from age 1 to 6 (immature period) for girth A and for age 7 to 12 ...

Fast development of seedling leaf area is a relevant trait in order to increase early resource acquisition. The use of semi-dwarf genotypes of wheat has decreased early vigour of modern cultivars. We studied early vigour ...

Victimization in early adolescence can have severe negative consequences later in life. Friendships are especially important in this time period. The present study investigated friendship selection and influence (contagion) ...
