Golf course managers manipulate cultural practices in preparation for golf tournaments to increase ball roll distance (BRD) short periods of time. Brushing putting greens, thought be a relatively minimally disruptive practice using brush attachments mounted mower units vertically orient leaf blades prior mowing, is growing popularity despite little research validating purported benefits. The ob...

Drought stress limits root growth and inhibits cytokinin (CK) production. Increases in CK production through overexpression of isopentenyltransferase (ipt) alleviate drought damages to promote root growth. The objective of this study was to investigate whether CK-regulated root growth was involved in the alteration of reactive oxygen species (ROS) production and ROS scavenging capacity under dr...

γ-Aminobutyric acid is a non-protein amino acid involved in various metabolic processes. The objectives of this study were to examine whether increased GABA could improve heat tolerance in cool-season creeping bentgrass through physiological analysis, and to determine major metabolic pathways regulated by GABA through metabolic profiling. Plants were pretreated with 0.5 mM GABA or water before ...

Ipomoea stolonifera (I. stolonifera) has been used for the treatment of inflammatory diseases including rheumatism and rheumatoid arthritis in Chinese traditional medicine. However, the anti-inflammatory activity of I. stolonifera has not been elucidated. For this reason, the anti-inflammatory activity of n-butanol extract of I. stolonifera (BE-IS) was evaluated in vivo by using acute models (c...

Soil cultivation is commonly used to manage organic matter (OM) accumulation in golf course putting greens. Our objectives were to determine: (i) if hollow-tine cultivation is more effective than solidtine cultivation at managing OM and water infiltration, (ii) if venting methods are effective at managing OM and water infiltration, and (iii) if venting alters or interacts with effects of earlyo...

Effects of amino acids and nitrogen on plant regrowth or recovery from drought stress remain largely unknown. The objectives this study were to examine how gamma-aminobutyric acid (GABA) proline, alone in combination, inorganic [ammonium nitrate (NN)] may differentially affect turf performance during rewatering, determine which specific endogenous regulated by GABA, NN priming associated with t...
