Abstract

The drought resistance was studied for four wheat cultivars: two dwarfs: Anahuac and IAC-24 and two tall ones: BH-1146 and IAC-23, using a treatment I constantly wetted by cailarity, and other one, II, which received water when soil water potential reached -1,5 MPa. Leaf water potential and relative water content were higher in treatment II than in treatment I, at the same soil water potentials for all cultivars, in the two development stages (vegetative, and reprodutive). There was no way of separating genotypes more or less resistant to drought, only using the relations between leaf water potential and leaf diffusive resistance to water vapour.
