Tratamento de sementes de brócolis com ácido salicílico

efeitos na produção de mudas

Abstract

The physiological potential of seeds is an important characteristic that can influence the performance of germination and plant growth. Seed treatment can help stimulate rapid and uniform plant germination and emergence, which can contribute to the production of vegetable seedlings. Salicylic acid is a compound that acts in the growth and development processes of plants. Thus, the objective of this research was to evaluate the effects of treating Romanesco broccoli seeds with different doses of salicylic acid (SA) on seedling production. The experiment was conducted at the Federal University of Fronteira Sul, Chapecó campus. Romanesco broccoli seeds, cultivar Otobrino, were used. The AS doses used were: 0, 2, 4 and 6 mMol/L. The variables analyzed were: plant emergence and seedling height, number of leaves, root length, and dry mass of roots and shoots of seedlings. The results obtained were submitted to analysis of variance and regression (p<0.05). There was an effect of AS doses only on plant emergence at seven DAS, with a percentage reduction as a result of increasing doses; for the other variables tested, there were no differences between treatments. Under the conditions in which this research was carried out, it can be concluded that the treatment of seeds of Broccoli, CV Romanesco, with the tested doses has no influence on the quality of seedlings produced in trays in a period of 35 days.
