Morphological and biochemical responses of turfgrasses to water deficit conditions.

Turf grasses are the most important cover plants in the world. Knowledge of relative drought resistance among the turf species/cultivars is important for selecting turf grass that persists during drought stress. A pot experiment was conducted to assess the morphological and biochemical responses of Bermuda grass cultivars (Khabbal, Dacca and fine Dacca) to water deficit conditions. The experiment was conducted in Completely Randomized Design (CRD) with four replications. Four drought levels at 75%, 65% and 55% field capacity along with 100% (control) were maintained throughout the experiment. Growth parameters including shoot fresh and dry weight, root fresh and dry weight, root/shoot ratio for fresh and dry weight, shoot length, root length, etc as well as photosynthetic characteristics and chlorophyll contents were measured. Data were analyzed using ANOVA technique and means were compared with Least Significance Difference test (LSD). Turf quality of all cultivars decreased with the progression of drought stress but “Khabbal” performed best as compared to other two grass cultivars for all attributes studied.
