The zinnia flower, due to its long flowering period and use as a cut flower, is a widely utilized ornamental plant. In this study, the effects of algae and fungus treatments on the vegetative and flowering traits of zinnia were investigated in the greenhouse of the Faculty of Agriculture at Zanjan University, using a completely randomized design with three replications. Two-week-old zinnia seedlings were obtained from the Zanjan Municipality Green Space Center and placed in uniform potting substrates in the greenhouse, consisting of equal parts garden soil, coco peat, and perlite. At this stage, the fungal treatment (Glomus mosseae, Gnomoniopsis castaneae, and a combination of both) was mixed into the soil at a rate of 15 gr. Once the plants reached the 4 to 6 leaf stage and their establishment and health in the greenhouse conditions were assured, the algae treatment (Spirulina algae, brown algae, and a combination of both types of algae) was applied at a concentration of 2% as a foliar spray. After the growth period and the onset of flowering, morphophysiological traits, including stem length, root length, leaf length, number of leaves, flower diameter, fresh and dry leaf weight, root volume, and physiological traits, including anthocyanin content, chlorophyll a, b, and total chlorophyll, were measured. The results indicated that the algae treatment had a significant effect on all traits except for stem length, while the fungal treatment significantly affected all traits except for stem length, root volume, and anthocyanin content. The results of this experiment indicated that this plant can achieve better growth and quality performance in the presence of a mixture of both algae or the fungus G. castaneae.
