Turfgrass Drought Resistance
Research Guide

What is Turfgrass Drought Resistance?

Turfgrass Drought Resistance investigates physiological, genetic, and management factors enhancing turfgrass tolerance to water deficit stress.

Research spans antioxidant enzyme responses (DaCosta and Huang, 2007, 191 citations), root-shoot dynamics (Carrow, 1996, 177 citations), and molecular markers (Budak et al., 2003, 211 citations). Over 1,700 citations across 10 key papers document mechanisms from bentgrass to zoysiagrass. Field and lab studies evaluate cultivars under drought conditions.

Key Challenges

Why It Matters

Drought-resistant turfgrasses reduce irrigation needs for landscapes, golf courses, and sports fields amid water scarcity (Huang et al., 2014, 229 citations). They support sustainable management in arid regions, with economic impacts rivaling hybrid corn seed production. Studies like Karcher et al. (2008, 146 citations) enable selection of tall fescue populations for summer survival, cutting water use by enhancing root/shoot ratios.

Key Research Challenges

Quantifying Genetic Variation

Identifying drought-tolerant germplasm requires precise molecular markers amid diverse buffalograss genotypes (Budak et al., 2003, 211 citations). Sequencing allotetraploid zoysiagrass genomes reveals structural challenges in trait mapping (Tanaka et al., 2016, 145 citations). Field validation lags behind lab genotyping.

Antioxidant Response Measurement

Species differences in enzyme activities like superoxide dismutase under drought stress bentgrasses demand standardized assays (DaCosta and Huang, 2007, 191 citations). Lipid peroxidation metrics vary with stress duration, complicating comparisons. Integrating with salinity tolerance adds complexity (Marcum and Murdoch, 1994, 183 citations).

Management Practice Optimization

Nitrogen effects on Kentucky bluegrass recovery post-drought require balancing growth and stress tolerance (Saud et al., 2017, 178 citations). Calcium chloride applications improve Zoysia japonica photosynthesis but need dosage optimization (Xu et al., 2013, 161 citations). Translating lab results to field conditions remains inconsistent.
