Autor: Osvaldo Chiavone-Filho, Fedra A. V. Ferreira, Thales Cainã dos Santos Barbalho, Humberto Neves Maia de Oliveira

Publikováno v: Journal of Chemical & Engineering Data. 62:1456-1463

Growing interest in the study of production conditions in the presalt led to the need to study complex systems at high pressures and temperatures, such as up to 70 MPa and up to 393 K. The aim of this work is to obtain vapor–liquid equilibrium data

Stability of genetic divergence among five mentrasto accessions in two environments

Autor: Luiz Orlando de Oliveira, Fedra A. V. Ferreira, Derly José Henriques da Silva, J.I. Ribeiro Júnior, Ney Sussumu Sakiyama, H. G. de Castro

Publikováno v: Cropp Breeding and Applied Biotechnology. 5:333-339

The stability of genetic divergence in five accessions of mentrasto (Ageratum conyzoides) was estimated in two environments (field and greenhouse) and for five harvest times. At each harvest, the following botanical agronomical traits were evaluated:
