Stimulation Effects of Glutamic and 5-Aminolevulinic Acids On Photosynthetic Pigments, Physio-biochemical Constituents, Antioxidant Activity, and Yield of Peanut

Abstract Soil not only represents the main supporter for root growth, but also is supplier of water and nutrients. However, several soils, i.e. sandy do adequately fulfill plant growth requirements environmental resources. Therefore, it necessary to compensate, even partially, lack these required resources better development. Amino acids could introduce a substantial solution in this respect. two field experiments under conditions were carried out investigate effect glutamic (GLA) 5?aminolevulinic (ALA) on photosynthesis pigments, oxidative defense indicators as well yield seed quality peanut. Three concentrations acid (10, 20 40 mg L ?1 , denoted GLA10, GLA20, GLA40, respectively) three acid, abbreviated ALA10, ALA20, ALA40, respectively), addition check treatment (tap water) applied. Treatments arranged randomized complete block design with replicates. Findings exhibited potentiality GLA20 recording highest values chlorophyll a, b, a/b, carotenoids total pigments compared other treatments. The increases indole acetic phenolics free amino 68.1, 58.9 19.6% 64.6, 51.2 17.7%, due application respectively. Substantial improvements pod ha oil %, flavonoids antioxidant activity obtained or ALA20. In conclusion, since at concentration showed promotive physiological biochemical status peanut, such should be adopted promising practice peanut cultivations.
