Knowledge of phenotypic and physiological traits associated with early responses to drought stress the extent damage is important for developing efficient irrigation programs selection drought-tolerant cultivars. This study was conducted identify major vegetation photosynthetic indices from imaging technologies that are correlated visual turf quality leaf water status responsive by comparative analysis different multispectral, hyperspectral, chlorophyll-fluorescence Kentucky bluegrass...
Abstract During periods of drought, the irrigation needs current warm‐season turfgrass cultivars and frequent municipal water use restrictions present a major challenge to industry. Turfgrass breeding programs have responded by placing more emphasis on improved drought response. 2012–2013, 560 genotypes four species developed five southern were evaluated for response in replicated field trials at seven locations. Breeders selected 35 as drought‐tolerant selections (DTS) further evaluation....
Extensive use of groundwater for irrigation has significantly depleted the Ogallala aquifer, threatening sustainability irrigated agriculture in Southern Great Plains. There is a need to identify low‐water‐requiring alternative crop and understand response that deficit strategies. The objective this study was assess biomass partitioning yield spring canola ( Brassica napus L.) under irrigation. Three diverse cultivars (‘H930’, ‘H955’, ‘L140’) were grown four different treatments; full season...
Abstract Drought and salt are two major stresses of turfgrass. Both damage the plant root system by disrupting osmotic balance at root–soil interface. The objectives our hydroponic experiments were to understand physiological biochemical responses in turfgrass species (seashore paspalum [ Paspalum vaginatum Swartz] centipedegrass Eremochloa ophiuroides (Munro) Hack.]) with distinct salinity tolerance exposed iso‐osmotic drought stresses. Two seashore genotypes, ‘Seastar’ ‘UGP113’, a...
Abstract Heat stress is a major abiotic that damages cool‐season turfgrasses, such as tall fescue ( Festuca arundinacea Schreb.), during summer months. results in oxidative damage, reductions photosynthesis, and ultimately can cause plant death. Exogenous applications of 5‐aminolevulinic acid (ALA) have previously been demonstrated to improve tolerance number crops by improving chlorophyll levels reducing two indicators heat plants. Experiments were conducted growth chamber conditions...
Abstract The objective of this study was to compare drought resistance in a range seashore paspalum ( Paspalum vaginatum Sw.) genotypes and identify associated morphological physiological traits. Fifteen were grown growth chamber conditions exposed well‐watered drought‐stress treatments. Genotypes ‘Seaisle1’ PI647891 consistent top performers, whereas ‘Seastar’ PI614680 performed poorly as measured by turf quality, percentage green cover, relative water content when stress. Observed levels...
