Abstract :
This study was conducted to investigate the effect of drought stress and plant population on re-transfer of materials and yield and some yield components of wheat cultivars in Dorud and Boroujerd regions located in Lorestan province in the crop year 2019-20. The experiment was performed as a factorial split-plot in a randomized complete block design with three replications. Drought stress treatment (in three levels of control, irrigation to flowering and irrigation to milk development) was plant density treatments (300, 400, 500 and 600 plants per square meter) and cultivar (Mihan and Baharan) were stand in sub plots. The results showed that drought stress, density and cultivar treatments had an effect on grain yield components and the interaction effect of stress * plant density on spike length and leaf area was significant. Also, the interaction effect of location * stress * cultivar on plant height, spike length and 1000-seed weight was significant. The highest plant height was obtained in irrigation treatment up to the milk development stage and Mihan cultivar cultivated in Boroujerd. The spike length in irrigation treatment up to flowering stage and at the level of 600 plants / m2 was higher than other experimental treatments. The highest number of spike per plant was in the control treatment. The highest 1000-seed weight was obtained in Mihan cultivar at the level of complete irrigation treatment in Dorud region and the highest grain yield was obtained in full irrigation treatment.
