Forest restoration in old pasture areas dominated by Urochloa brizantha
, 2023 No presente estudo foi avaliada a densidade de recrutas em uma área em restauração florestal previamente ocupada por pastagem de Urochloa brizantha e em uma Floresta Semidecidual. Foi avaliado o efeito da luz disponível sobre a biomassa da grama exótica e investigamos as associações da densidade de recrutamento com as variáveis do solo e a ...

Minimum Number of Measurements for Accurate Evaluation of Qualitative Traits in Urochloa brizantha
Journal of Agronomy, 2015 A B S T R A C T This work aimed to identify the most effective method to estimate the coefficient of repeatability in genotypes of U. brizantha and predict the minimum number of measurements required for some qualitative traits. It were evaluated 9 genotypes in a randomized block design with two replications in the rainy season and drought in 2000.
