Abstract/Contents:"Heat stress is a major factor limiting growth of cool-season grasses during summer. The objective of this study was to investigate whether heat injury in creeping bentgrass could be prevented or suppressed by applying biostimulant and nutrients. 'Penncross' plants were exposed to two day/night temperature regimes: 20/15 C (control) and 35/30 C (heat stress) in growth chambers. Foliar application of 10 ml of CytoGro (a cytokinin-like compound, 5 ppm), CaC12 (10 mM), KH2PO4 (10 mM) and NH4NO3 (124 mM) before and during heat stress increased chlorophyll content, Pn, Fv/Fm, turf quality, root and shoot growth, and affected antioxidant enzyme activities (SOD, CAT, POD, and APX). However, their effectiveness in improving heat tolerance varied, with NH4NO3 having the most pronounced, beneficial effects."
