Popis:	The research, carried out in the Martonvásár phytotron in 2007, was aimed at determining how the leaf water potential of maize hybrids produced in direct and reciprocal crosses, and thus possessing different levels of seed vigour, changed as the result of water withholding in the flowering phenophase. In the case of the silage maize hybrids Mv 290 and Lima it was found that seedling vigour influenced the plant height (measured at 30 days) of adult plants. Crosses produced on chilling-sensitive female genotypes (GL, AM, H29), such as the hybrids Káma, Maraton and Hunor, proved to be unambiguously stress-sensitive if water was withheld for more than six days. In all cases drought stress reduced the relative quantum efficiency, irrespective of the crossing combination.
