Sažetak
The effect of water reduction stress on photosynthetic efficiency and 1 agronomic traits of ten bread winter wheat cultivars was investigated aiming to develop breeding methods for improving wheat drought tolerance. In 2008 – 2009 crop seasons, the trial was grown in vegetative pots according to the method of two-factorial experiment (cultivar and treatment) as a randomized complete block with three replications. A stressful version of the treatment was exposed to mild water reduction short-term stress three times (end of tillering stage, flag leaf to beginning of heading stage, and grain filling stage). Three photosynthetic efficiency parameters (Fv/Fm, ET0/ABS and PIABS) were investigated at the end of tillering stage (water content of soil: 22.4 - 28.8% volume for stressful variant and 29.8 - 37.9% volume for control) and six agronomic traits were estimated before and after winter wheat harvest. Significant differences were detected among cultivars for all investigated traits. The investigation revealed that water reduction stress decreased all examined agronomic traits. However, photosynthetic parameters mostly had higher values during mild short-term drought stress conditions. In addition, significant interaction between cultivars and treatments was detected for 1000 grain weight, grain number per spike, but there was not any significant interaction for harvest index, number of spikes per pot, grain yield and biomass per pot nor for photosynthetic efficiency parameters.
