Biometria em plantas de milho submetidas ao alagamento

Abstract

The importance of maize (Zea mays) is not only in the production of an annual crop, but in any relationship that culture has on Brazilian agricultural production, both with regard to economic factors as social factors. Ali aspects of growth and development of plants can be affected by water stress and water saturation in the tissues caused by excessive evaporative demand and / or limited water supply. The aim of this study was to evaluate the effects of flooding on relative water content, number of leaves, dry weight of stem, root dry mass and leaf dry weight in maize plants subjected to flooding. The experiment was conducted in a greenhouse at the Federal Rural University of Amazônia (UFRA - Capitão - Poço), using com plant variety BR 5102, the experimental design was completely randomized design (CRD) with 2x4 factorial, with two conditions water: control, drought and four cycles of stress with 5 repetitions. Achieved significant results in ali parameters evaluated, concluding that the flooding negatively in biometrics plants.
