We review the detrimental effects of waterlogging on physiology, growth and yield of wheat. We highlight traits contributing to waterlogging tolerance and genetic diversity in wheat. Death of seminal roots and restriction of adventitious root length due to O2 deficiency result in low root:shoot ratio. Genotypes differ in seminal root anoxia tolerance, but mechanisms remain to be established; ethanol production rates do not explain anoxia tolerance. Root tip survival is short-term, and thereafter, seminal root re-growth upon re-aeration is limited. Genotypes differ in adventitious root numbers and in aerenchyma formation within these roots, resulting in varying waterlogging tolerances. Root extension is restricted by capacity for internal O2 movement to the apex. Sub-optimal O2 restricts root N uptake and translocation to the shoots, with N deficiency causing reduced shoot growth and grain yield. Although photosynthesis declines, sugars typically accumulate in shoots of waterlogged plants. Mn or Fe toxicity might occur in shoots of wheat on strongly acidic soils, but probably not more widely. Future breeding for waterlogging tolerance should focus on root internal aeration and better N-use efficiency; exploiting the genetic diversity in wheat for these and other traits should enable improvement of waterlogging tolerance.

“…Waterlogging at generative development, e.g., during anthesis, impairs reproductive organs. The floret fertility can be diminished, which leads to reductions in grain number per spike (Marti, Savin, & Slafer, ) and hence lower yields. The amount of yield loss depends on several factors such as growth stage of the plants (de San Celedonio et al., ) or duration of the waterlogging event (Malik et al., ).…”

Oilseed rape suffers from serious waterlogging in many regions of the world limiting the cultivation area for rapeseed. Due to the man‐induced climate change, the risk of severe waterlogging events and associated therewith the damage of rapeseed plants will increase, even in Europe and North America. To investigate the effects of waterlogging on growth, yield and seed quality, rapeseed was cultivated throughout its vegetation period and waterlogged for 14 days at two different growth stages: at stem elongation (BBCH 31) or at floral bud appearance (BBCH 55). The experiments revealed that waterlogging at BBCH 31 affected plant growth and nutrient accumulation and finally resulted in lower yields. Waterlogging at BBCH 55 seriously impaired main racemes, but due to an increased production of secondary racemes, yield losses were lower than after waterlogging at BBCH 31. Oil quality was not affected by any waterlogging treatment under the chosen experimental conditions.

“…The negative effects of waterlogging on the attributes related to growth (i.e. biomass accumulation and its partition) in wheat and barley have been widely described in the literature (Cannell et al 1980, Musgrave 1994, Setter and Waters 2003, de San Celedonio et al 2014b, Marti et al 2015. However, its effects on crop development have been analysed to a lesser extent.…”

The aim of this study was to analyse (i) the crop attributes that determine flowering time (i.e. final leaf number, FLN; and phyllochron, Phy), (ii) the dynamics of tiller appearance and (iii) the synchrony between leaf and tiller appearance in wheat and barley plants exposed to waterlogging. Two experiments were carried out in pots, in which wheat and barley cultivars were exposed to five waterlogging treatments, during different periods throughout the crop cycle, from emergence to maturity. The appearance of leaves and tillers on the main stem was measured twice a week in labelled plants. Waterlogging from emergence to flag leaf appearance significantly delayed time to flowering. The delay was greater when waterlogging occurred at the beginning of tillering, lengthening the period from emergence to flowering 24 % (13–15 days) in barley and 10–15 % (6–10 days) in wheat, as compared to control. Phy was the main attribute explaining the delay in flowering, as FLN was not altered. Waterlogging during the early stages of development reduced tiller appearance rate (TAR) in both species, but this effect was partially counterbalanced by a lengthening of the tillering phase, so the effect on final tiller number at maturity was limited. In conclusion, the exposure of wheat and barley to waterlogging during early stages of development delayed time to flowering and reduce TAR in both species. Waterlogging during more advanced crop stages produced slight effects on tillering dynamics, which would indicate that waterlogging affected structure generation more than mortality.
