Abstract

The impact of arbuscular mycorrhizal (AM) fungi inoculation with mixed water irrigation on the vegetative and flowering growth, leaf mineral content, and chlorophyll (Chl) content of Antirrhinum majus L. (snapdragon) plants was studied through two seasons under two irrigation water sources. Five irrigation water treatments were applied as follows: T1 as a control (100% desalinized (DW)), T2 (75% DW + 25% well water, WW), T3 (50% DW + 50% WW), T4 (25% DW + 75% WW), and T5 (100% WW). The imposed salt stress conditions (T5) significatly reduced all vegetative and flowering growth, leaf mineral content (P, Na, K, Cl, and Ca), and chlorophyll content of the plants compared to those of the non-salted plants (T1). Inoculated snapdragon with AM fungi exhibited significantly higher values for most vegetative growth characters, flowering date, and spike length than those of non-mycorrhizal plants. With regard to interaction effects, the highest value of proline content of the leaves was detected with 100% WW (T5) and AM fungi treatments, which improved the salt stress tolerance compared to other treatments. Inoculated snapdragon plants with AM fungi showed both improved vegetative and flowering growth, mostly under salt stress conditions. With (T3) under mycorrhizal treatment, snapdragon plants showed the best results with earlier flowering dates, greater number of spikes, and longer spike length.
