An experiment was performed to investigate the effect of mycorrhizal symbiosis and foliar application of salicylic acid on quantitative and qualitative traits of maize during 2018 and 2019 in the research farm of Islamic Azad University, Chalous Branch. Split plot in a randomized complete block design with three replications was used. Experimental factors included mycorrhiza species of (G. mosseae), (G. geosporum) and (G. intraradices) at two levels (no consumption and consumption of mycorrhiza) and salicylic acid at two levels (no consumption and consumption of 1 mμ of salicylic acid). Results of interaction effects of mycorrhiza and salicylic acid on the measured traits revealed that the maximum 1000-grain weight, grain yield, biological yield, phosphorus, potassium, nitrogen percentage and yield of maize grain protein were observed in G. mosseae treatment under foliar application of salicylic acid. Foliar application of salicylic acid increases the root length and provides the necessary conditions for increasing water and nutrient uptake alongwith increase in photosynthesis and thus allocates more photosynthetic substance for development of reproductive organs. Hence, it increases maize grain weight and accordingly grain yield. In general, the results revealed that mycorrhiza and foliar application of salicylic acid increase growth indicators, yield and yield components. It also improved the quality traits of the maize plant. Based on results, the interaction effect of G. mosseae treatment and foliar application of salicylic acid yielded better results than other treatments. Mycorrhiza increases the number of grain in the ear, the number of rows in the ear, increases the plant's ability to absorb phosphorus, and the increase of mycorrhiza along with salicylic acid shows the maximum grain yield in maize. Finally, it can be concluded that the use of mycorrhiza and salicylic acid can be effective in increasing grain in the plant.
2018 年和 2019 年，在伊斯兰阿扎德大学查洛尔斯分校的研究农场，进行了一项实验，以研究菌根共生和水杨酸叶面喷施对玉米数量和质量特性的影响。采用裂区随机完全区组设计，三次重复。实验因素包括：（G. mosseae）、（G. geosporum）和（G. intraradices）三种菌根物种，分为两个水平（不消耗和消耗菌根）和水杨酸，分为两个水平（不消耗和消耗 1 mμ 水杨酸）。菌根和水杨酸互作效应对测量性状的影响结果表明，水杨酸叶面喷施处理中，G. mosseae 处理的千粒重、籽粒产量、生物产量、磷、钾、氮百分率和玉米籽粒蛋白质产量最高。水杨酸叶面喷施增加了根长，并为增加水分和养分吸收提供了必要的条件，同时增加了光合作用，从而为生殖器官的发育分配更多的光合物质。因此，它增加了玉米籽粒的重量，从而提高了籽粒产量。总的来说，结果表明，菌根和水杨酸叶面喷施增加了生长指标、产量和产量构成。它还改善了玉米植株的品质特性。基于结果，G. mosseae 处理和水杨酸叶面喷施的互作效应比其他处理产生了更好的效果。菌根增加了穗粒数、穗行数，提高了植物吸收磷的能力，菌根与水杨酸的增加表现出玉米的最高籽粒产量。最后，可以得出结论，使用菌根和水杨酸可以有效地增加植物中的籽粒。
