Pathway Weathering in Granitoid Rocks from Central Region of Angola: Geochemica...
Duarte, Isabel M. R.; Mirão, José A. P.; Rocha, Fernando J. T.; Bonito, Fernando A. B.; Queta, Felisberto M.; Falcão, WinnieThe Central Region of Angola is characterized by the abundance of granitoid rocks, whose weathering “in situ” originated the so-called residual soils. The textural, geochemical and mineralogical properties of these soils depend not only on the chemical composition of parent rock, but mainly on the local climatic and geomorphological characteristics. In the study area, sampling sites were selected, which extend ...
Chickpea genotype adaptation to Mediterranean Environment
Simões, Nuno; Duarte, Isabel M.; Silva, Luis Leopoldo; Lourenço, Maria Ermelinda V.L.; Chaves, Manuela M.Genotypes that fasten their development cycle showed higher grain yield. Earlier start of flowering means higher soil water availability and lower maximum temperatures (middle of April), allowing to set more flowers and pods per plant and consequently higher grain yield. End of flowering started on May 19 in earlier genotypes. On this date the most hydrated genotypes are the ones with the longest growth cycle...
Screening chickpea resistance to water deficits: the yield perspective.
Duarte, Isabel M.; Silva, Luis Leopoldo; Simões, Nuno; Imtiaz, M.; Pinheiro, Carla; Lourenço, Maria Ermelinda V.L.; Chaves, Maria ManuelaScreening a wide range of germplasm from our major crops (including legumes) to search for genetic variation of traits involved in stress resistance is extremely relevant in the context of predicted increase in aridity in several areas of the world, including the Mediterranean (1,2). On the other hand, the keystone of ‘crop drought resistance’ relies on the effective use by the crop of a limiting water supply (...
