Enzymatic activity on quinoa leaves (Chenopodium quinoa, Willd.), under abiotic stress

Abstract

Quinoa (Chenopodium quinoa sp.), is a species known throughout the world, native to Latin America, and is increasingly appreciated in many parts of the world. The aim of the research was to evaluate fertigation and irrigation on the enzyme activity in the leaves of two cultivars of quinoa (Vikinga and Puno), for its introduction as vegetable crop. The experiment was carried out in the IULS Iasi greenhouse, in vegetative pots, of 42 variants, the experiment was organized in randomized blocks. The results obtained, under the influence of the factors: cultivar, fertilization and irrigation, show that the most intense enzymatic activity was evidenced in Vikinga cultivar - chemically fertilized variant, with irrigation 50% of the substrate field capacity. The results are positively correlated with the increase in the amount of chemical fertilizer administered. The most evident decreases in CAT activity were evidenced in the experimental variants to which Micoseed MB® was applied, in both cultivars.
