Comparison between Photosynthesis and Growth Indicators of C4 and C3 Grasses as Influenced by Wastewater

The use of treated wastewater is one of the ways to resolve a lack of water concerns. In this study, different responses of two kinds of grasses (C 3 : Lolium perenne L. and C 4 : Cynodon dactylon L . ) and four levels of wastewater (control, 25, 50, 75, and 100%) were evaluated at morphological and...

Summary:The use of treated wastewater is one of the ways to resolve a lack of water concerns. In this study, different responses of two kinds of grasses (C 3 : Lolium perenne L. and C 4 : Cynodon dactylon L . ) and four levels of wastewater (control, 25, 50, 75, and 100%) were evaluated at morphological and physiological levels. The concentration of Cd, Cr, Ni, As, and Cu elements significantly increased in leaf tissue under the toxic levels of wastewater (100%). The results showed that P n , T r , g s , WUEi, and chlorophyll significantly increased when grasses were under 50% wastewater treatment. Plants growth parameters including root, and shoot dry weights exhibited a significant increase under low concentration of wastewater while photosynthetic index and growth parameters showed a high reduction under high wastewater concentration. The results showed that by the handling of wastewater and the utilize of suitable concentrations, this unusual water source can be used for irrigation of grasses that need high water demands such as Lolium perenne and Cynodon dactylon .
