Análise de crescimento de milho em condições de alagamento

Abstract

The objective of this work was to evaluate the influence of flooding on the growth of maize plants through growth analysis through simple logistics. The work was conducted in the 2016/2017 growing season. The climate is temperate, with well distributed rainfall, hot summer andthe soil is classified as solodiceutrophic haplic planosol. The experimental design was completely randomized blocks arranged in a factorial scheme, with two soil water conditions x five plant samples, arranged in four replicates. It was carried out the flooding of the parcels. The variables measured were total dry mass; dry matter production rates; relative growth rate; net assimilation rate; leaf area ratio; leaf mass ratio; maximum values of specific leaf area; leaf area index; efficiency of solar energy on version and mass partition, carried out in five collections. There is a reduction in leaf mass ratio, dry mass production rate, and relative growth rate in plants submitted to flooding, compared to those kept at field capacity. Corn plants submitted to soil flooding presented negative changes in the assimilated partition throughout their development. Soil flooding over the period of 72 hours adversely affects the physiological parameters of maize plants, leading to a reduction of their productive efficiency.
