Efeito da salinidade no desenvolvimento inicial de mudas de Mimosa scabrella Benth
Iheringia, Série Botânica, 2019 Under natural conditions, plants are subject to stresses that limit their development and chances of survival, as is the case of soil salinity. The aim of this study was to evaluate the effects of salinity in the early development stages of bracatinga seedlings. A completely randomized design was used in factorial 2 (0 and 3 g/L slow-release fertilizer)

Cropp Breeding and Applied Biotechnology, 2006 Heritabilities and expected selection gains were estimated in nine provenances of Mimosa scabrella Bentham by means of random and mixed reproduction models. In the random model, the relationship coefficient was considered as half-sibs, and in the mixed, relatedness was estimated based on parameters of the mating system.
