When drought occurs in the pre-flowering of maize with high intensity and average duration of twelve days, it promotes changes in the centesimal composition of grain and reduces yield grains by up to 60%. Therefore, this work aims to evaluate the changes in yield grain and in organic and mineral composition of grains of four maize genotypes with contrasting characteristics for drought tolerance submitted to severe drought in pre-flowering. For this, under greenhouse conditions, drought-tolerant genotypes (DKB390 and P30F35) and drought-sensitive genotypes (BRS1010 and 2B710) of maize were submitted to two water conditions: field capacity and water deficit. Drought was imposed in pre-flowering and maintained for twelve days. The leaf water potential and at the end of the cycle the components of productivity was evaluated. Dry grains were ground and a sample obtained for analysis of organic and mineral composition. We verified that, water deficit promoted a reduction in the number of grains per row in all genotypes. However, only BRS1010 and 2B710, two drought-sensitive genotypes, had their final grain yield reduced. All genotypes under drought conditions reduced starch content and increased protein levels in their grains. Phosphorus, iron, magnesium, zinc, manganese and copper levels increased in plants under water deficit. On the other hand, calcium content was reduced by drought in all genotypes. |
