Influence of foliar fertilization with amino acid preparations on morphological traits and seed yield of timothy

Abstract

Amino acids are organic chemical compounds and are the building blocks of proteins, which perform structural, metabolic and transport functions in plants (Liu et al. 2008). Amino acids are the precursors of phytohormones and other growth substances. Amino acids improve the efficiency of the plant's metabolism to induce yield increases and enhance crop quality, increasing plant tolerance to and recovery from abiotic stresses, facilitating nutrient assimilation, translocation and use, enhancing quality attributes of product (Calvo et al. 2014), promoting the processes of plant respiration, photosynthesis, protein synthesis, strengthening plant growth and yield formation (Davies 2010).
