Abstract Effects of water and high temperature stresses, either separately or in combination, over biomass accumulation, grain yield and its direct components grain number per ear and individual grain weight], as well as harvest index were determined in four tropical maize populations. Results indicated that water stress do not significantly affect the studied variables, due to the absence of a severe water stress during flowering. This was the result of the fallen precipitation at this time. The most important factor in this study was high temperature, which significantly reduced all studied variables, except individual grain weight. High temperature stress reduced aerial… More >
