Abstract:

Our knowledge on the genetic base of the fall dormancy of turfgrass is still limited. Furthermore, little is known about the dormancy inducing mechanisms in turfgrass. The object of this study was to understand the function of the illuminating treatment time in the turfgrass dormancy inducing mechanisms, to better understand turfgrass fall dormancy. In this experiment, Bermudagrass (Cynodon spp. Rich.) cultivar ‘Tifton419’ and Kentucky bluegrass (Poa pratensis L.) cultivar ‘Midnight II’ were used as representatives of warm-season and cold-season turfgrass, respectively. Cold-season and warm-season turfgrass samples were put into three incubators separately, 11 h, 8 h and 6 h illuminating treatment were adopted in this experiment. Samples were taken 5 times from each treatment to determine some physiological properties in the turfgrass root systems, such as soluble sugar, endogenous hormones and soluble protein. There were significantly different levels of nutrients  and gibberellin (GA) and abscisic acid (ABA) in turfgrass root systems resulting from different light treatment times. Soluble protein, soluble sugar and ABA levels increased with illuminating treatment time decreasing, while GA concentration decreased at the same time. Synthetic analysis suggests that the illuminating treatment time reduction is one of important inducing factors causing fall dormancy in turfgrass.
