The reproductive growth of oilseed rape crops is exposed to drought stress in many areas of Iran. Our objective was to examine the effects of short and long periods of water stress during different growth stages of canola on yield, yield components, seed oil and protein contents. In a pot experiment, Hyola-308, PF-7045/91 and Heros cultivars were planted in eight treatments including short and long periods of water stress during different growth stages. These three cultivars were also exposed to different water stress intensities in a biennial field experiment. The greatest seed yield reduction was observed when water stress occurred at flowering (30.3%) and then at silique development (20.7%). Seed yield reduction by short-term water stresses during stem elongation, flowering and silique development were mostly associated with the reduction of silique number per plant, but by short-term water stress during seed development was due to the reduction of seed weight. A little compensation was observed by seed weight when water stress occurred before flowering. The number of siliques per plant was the most sensitive yield components under long-term water stress. Seed oil content decreased by water stress but protein content increased. |
