Abstract
The aim of the experiments was to monitor the immediate impact of water deficit on the energy content in selected genotypes of maize. A broader genotype set of maize types was selected as the experimental material (5 in-bred parental lines and their cross-breeds).
The maize plants were cultivated under controlled conditions in a greenhouse - the control group and the stressed group.The plants from the control group were irrigated at 70% of the field water capacity. In the stressed group, irrigation was completely stopped for 18 days.The dry matter of above-ground biomass was identified.
It follows from the obtained results that the DM of above- ground biomass was lowest in the stressed plants about 20.23%. The genotypes (23x704)x704 and 2023 responds sensitively to stress caused by drought and the genotype CE704 seems to be tolerant to this kind of stress.
