Evaluation of biologic fertilizers and mycorrhizal fungi on phonological and physiological traits of two varieties of Antirrhinum majus

Snapdragon flower is one of the beautiful ornamental plants that are also cultivated for medicinal purposes. The use of chemical fertilizers and their negative effects on human health have led to the advancement of the use of biological and organic fertilizers in agricultural products. This research was conducted with the aim of investigating the application of fertilizers and mycorrhizal traits of two varieties of snapdragon flower in 2021–2022 in the greenhouse of Agriculture Research at the Research Institute of Zabol. The experiment was conducted in a factorial based on a completely randomized design with three replications. The investigated factors included the varieties (yellow and red flowers) and fertilizer treatment (Glomus intraradices, Glomus mossaea, supermycoplus and control). The results of this study showed the effect of variety was significant on all phonological traits, except in the time of four-leaf formation. Fertilizer treatment also had a significant effect on all phenology traits, while the interaction of variety and fertilizer treatment was significant only on two phenology traits: time of first leaf formation and four-leaf formation time. The red variety led to the occurrence of phonological traits earlier than the yellow one, in most of the phonological traits. The results showed that the yellow variety was superior to the red variety in all the physiological traits except for the phenol of the leaf and the flavonoid of the flower. Supermycoplus was better than the control and the mycorrhizal fungi, in the traits of: The phenolic, flavonoid and DPPH of the leaves and the flavonoid of the root, among the fertilizer treatments. In general, the use of biofertilizers and mycorrhizal fungi is recommended due to their positive effects on the physiological traits of snapdragon flowers.
