Interactive effects of waterlogging and salinity on perennial ryegrass and alkaligrass

A lot of salt-affected soils in the world are also affected by compaction and waterlogging due to shallow water tables or decreased infiltration sodicity. Waterlogging cause reduced oxygen exchange (hypoxia). Research on combined impacts salinity hypoxia turfgrass growth is limited. The interactive effects availability nine perennial ryegrass entries (Lolium perenne L.) one alkaligrass [Puccinellia tenuiflora (Jacq.) Parl.] cultivar were studied. In a controlled greenhouse, grasses subjected 4 treatments: control, salinity, hypoxia, + for 12 weeks. All exhibited clipping yield both treatments except ‘Fults’ alkaligrass. With without treatment, was most salt tolerant grass among all entries. general, had better turf quality control than with treatments. more severely (quality yields) under treatment compared only. Plant Na+ Cl− concentrations increased experimental (‘10.0824’ ‘10.0825’) able maintain other cultivars combination
