The amino acids are one of the major cellular components of plants, which are involved in different metabolic pathways. In present study, effect of artificial gravistimulation on amino acid profiles of pea, rice, corn, wheat during early growth stages was investigated. One-axis clinostat was used for gravistimulation application, which was applied at embryonic stage. Amino acid profile was measured in 10-days old seedlings of pea, rice, corn and wheat cultivars. The effect of clinostat rotation was also evaluated under salt stress and MS medium supplement. Germinated pea, rice, corn and wheat seedlings were grown under the gravity condition for specific time interval. Corn and wheat seeds showed slow germination as compared to pea and rice cultivars. The rate of amino acid formation under gravity condition was significantly higher than control (un-treated seedling). The variation in amino acid profile of pea, rice, corn and wheat cultivars vary deferentially. Results revealed that gravistimulation applied through clinostat has positive effect on amino acid profile in plant tissue and future studies should be focused on growth, biochemical, physiological at lateral stages of growth.
