| Abstract/Contents: | "Cytokinin Effects on Shoot and Root Growth of Creeping Bentgrass In Relation to Heat Stress. Heat stress is a major environmental factor limiting growth and quality of cool-season turfgrass during summer in the transitional zone and warm climatic areas. The objectives of this study were to examine whether exogenous application of zeatin riboside (ZR) would enhance heat tolerance of creeping bentgrass and to determine the effective concentrations of ZR. 'Penncross' creeping bentgrass was subjected to high soil temperature (20/35 C air/soil) alone and high air and high soil temperatures (35/35 C) for 56 d in growth chambers. Four concentration of zeatin riboside (ZR), 0.01, 0.1, 1 and 10 μmol, and 50 ml of water were applied to the root zone at the beginning (0 d) and 14 d of heat stress. Applications of 1 and 10 μmol ZR mitigated heat stress injury to shoots and roots, with 10 μmol ZR being more effective when applied at either 0 or 14 d of heat stress. Application of 0.1 μmol ZR alleviated high temperature injury for a shorter period and was less effective than 1 and 10 μmol ZR. Application of 0.01 μmol ZR had no effects on shoot and root responses to high soil temperature alone or in combination with high air temperature." |
