| Abstract/Contents: | "As average global temperatures rise, cool-season C3 grasses, such as the most commonly grown Kentucky bluegrass (Poa pratensis L.), struggle to tolerate extreme summer heat and require more of increasingly scarce water. Hybrid Bermudagrass [Cynodon dactylon (L.) Pers. ΠC. transvaalensis Davey] is a warm-season C4 grass that may be increasingly more suited for northern ecosystems traditionally classified as cool-season climates. The objective of this study is to evaluate two C. dactylon (L.) Pers. ΠC. transvaalensis Davey varieties compared to a blend of P. Pratensis L. varieties for water loss and canopy health, temperature, and growth when mowed at moderate or short heights in all combinations of deficit, moderate, and excessive irrigation. Surprisingly, mowing height had few impacts in relation to irrigation rates. Although the results of the study show that the two types of C. dactylon (L.) Pers. ΠC. transvaalensis Davey respond differently to deficit irrigation, both had significantly more root growth than P. pratensis L., with roots that stretched deeper and had a greater biomass. While C. dactylon (L.) Pers. ΠC. transvaalensis Davey also produced greater shoot biomass than P. pratensis L., the latter had a higher shoot to root ratio. The results of this direct comparison with P. pratensis L. and C. dactylon (L.) Pers. ΠC. transvaalensis Davey reinforce the notion that the latter has more extensive root systems to extract water from a greater volume of soil, which will decrease irrigation needs as this species is potentially used more frequently in cool-season climes." |
