Bioestimulants on common bean (Phaseolus vulgaris L.) cultivar TAA Marhe in vitro

Abstract

Plant biostimulants are substances that can increase plant germination growth, and development, acting on the stimulation of cell division. This study aimed to evaluate the in vitro action of two commercial biostimulants AgroRaiz® and Stimulate® on the physiological quality of seeds of Phaseolus vulgaris cultivar TAA Marhe. Seeds of the TAA Marhe cultivar were used at the usual concentration of both biostimulants AgroRaiz® 0.3 L 100 kg-1 and Stimulate® 0.5 L 100 kg-1 seeds. Classic germination test, dry matter, root length and accelerated aging test were performed. The experimental design was completely randomized with three treatments and four replications. The usual doses of biostimulators did not influence the germination rate and dry mass by the classical method; however, Stimulate® demonstrated action on mean root length. For the aging assay, AgroRaiz® proved to be superior to Stimulate® in germination and seedling dry matter.

Soybean response (Glycine max L.) under the use of biostimulants: A literature review

“…Biostimulants are substances with the capacity to help improvement the nutritional efficiency of plants, helping to withstand problems of biotic and abiotic stress, such as diseases, temperatures, cultivation conditions and cultivation environments, and may increase production without taking into account the nutritional content (Nair et al, 2019). At this point, several studies have been carried out to investigate the influence of biostimulants on the production of legumes, such as soybeans, seeking to meet the growing world demand (Vasconcelos, 2019;Sauvu-Jonasse et al, 2020;Cavalcante et al, 2020;Katu et al, 2022).…”
