Water use efficiency, morpho-physiological and biochemical reactions of some bedding plants to drought stress
The purpose of this experiment is to compare the growth and water consumption efficiency of five garden plants (marigold (Tagetes erecta ‘Red Brocade’), moss-rose (Portulaca grandiflora ‘Sun Rose’), dahlia (Dahlia sp. ‘Double Opra’), gazania (Gazania splendens ‘New Day’), and Indian blanket (Gailla...

The purpose of this experiment is to compare the growth and water consumption efficiency of five garden plants (marigold (Tagetes erecta ‘Red Brocade’), moss-rose (Portulaca grandiflora ‘Sun Rose’), dahlia (Dahlia sp. ‘Double Opra’), gazania (Gazania splendens ‘New Day’), and Indian blanket (Gaillardia pulchella. ‘Sun Dance’)) during the warmer seasons of the year under various levels of drought stress based on field capacity (FC; 25, 50, 75, and 100 %). The interaction effect of plant × drought stress (FC) on the fresh and dry mass of aerial and underground organs was significant. Decreased water availability resulted in a drop in growth parameters (leaf fresh and dry mass and leaf area). In compared to the growth of aerial organs, root biomass increased in response to drought stress. Marigold, Indian blanket, and dahlia plants had the highest root-to-shoot ratio in extreme stress, i.e., FC 25 %. The plant × drought stress interaction significantly influenced flower number, whereas flower diameter was influenced by the main effect of plant and drought stress (not their interaction). The FC 100 % and FC 25 % treatments had the highest and the lowest accumulations of proline and soluble sugars, respectively. Moss-rose, gazania, and marigold ornamental plants had the highest water use efficiency at 75 %, followed by Dahlia at 50 % and moss-rose at 25 %.
