Abstract: (922 Views)
Survival of ornamental plants as a vital factor in green spaces has been threatened by climate change and drought stress. An experiment was designed to investigate the effect of soil modifiers on the growth of two plants of the Hollyhock ecotype under drought conditions at Ferdowsi University of Mashhad in 2021. Experimental Treatments included two ecotypes (Mashhad, Tehran), three drought stress levels (80, 60, 40% FC), and four substrates (soil, soil + manure, soil + rice hull, soil + wheat straw). Macroelements (nitrogen, phosphorus, and potassium) of leaves, physiological characteristics of plants, (total chlorophyll, proteins, and enzyme activities), and morphological traits (height, the diameter of the stem, number of leaves, bud, flowers, and leaf area) were measured. The effect of time on the number of Hollyhock leaves under drought stress was also recorded. Treatments affected all physiological and growth parameters of Hollyhock plants, and a significant amount of physiological traits (chlorophyll) and growth parameters were recorded in the Mashhad ecotype below 80% FC in soil + manure. The triple interactions of ecotype, drought stress, and culture medium on protein content, superoxide dismutase activity, and ascorbate peroxidase activity were not significant, but enzyme activity was increased with increasing drought stress. Also, the number of leaves and flowers had a decreasing trend with increasing drought stress. The results showed that applying manure with soil by providing macro elements reduced the adverse effects of drought stress in Hollyhock and increased drought stress resistance in both ecotypes.
