Abstract
In pot trials the effects of waterlogging on water use and nutrient uptake in sunflower and sorghum were investigated in relation to stage of development of the crops and the timing and duration of waterlogging. Waterlogging at the vegetative and floral initiation stages of plant growth induced a reduction in water use in sunflower, with corresponding declines in leaf expansion and leaf water potential; in sorghum, the transpiration rates were much lower than for sunflower and relatively unaffected by waterlogging. Waterlogging at anthesis, however, caused an immediate reduction in water use in sunflower with a similar but delayed effect in sorghum. The differences in response of these 2 spp. are discussed in relation to the relative importance of water stress and nutrient uptake. Plant analysis at maturity indicated that waterlogging at any growth stage reduced both total and seed P contents in sunflower; similar effects were recorded with sorghum, except that waterlogging at anthesis did not reduce nutrient uptake. Waterlogging effects on plant K levels were variable
