Abstract

This research was conducted to investigate the effect of planting densities on some morphophysiological characteristics of sports turfgrass under low water stress conditions. The experiment was carried out in the form of split plots, based on a randomized complete block design with three replications. Treatments included low water stress at three levels of 90 (control), 60 and 30% of field capacity (FC), and planting density of 20, 30, and 40 g seed/m2. Seeds were planted according to the desired densities in plots measuring 2×3 m2. Two months after planting, low water stress was applied for three weeks. The results showed that the treatments had a significant effect on the evaluated traits. The highest fresh and dry weight of the aerial part, leaf length, and total chlorophyll content was observed in 90% FC and the density of 20 g seed/m2 treatment. The highest root fresh and dry weight, root volume, and total carbohydrates were obtained in 30% FC and density of 20 g seed/m2 treatment. Moreover, the highest proline content was in 30% FC and density of 40 g seed/m2 treatment. According to the results, the planting density of 20 g seed/m2 and 90% FC had a more favorable effect on the vegetative and physiological indicators of sport turfgrass.
