Abstract:
The effect of a mild water stress around anthesis on the root system of two maize hybrids grown on a Typic Argiudoll was studied. Between the 0.5 and 1.4 m depth, root length and biomass densities increased under water stress for both hybrids, while between 0 and 0.5 m, root length density increased as an effect of drought only in one of the hybrids. The largest difference between water treatments was observed in the B(2t) horizon (0.5-0.9 m). The results observed could be a consequence of plant-related mechanisms, like osmotic adjustment, and/or soil-related characteristics, like soil structure. This response probably led to an improved water uptake below the B(2t) horizon under water stress.
