Resumo: | There are reports that strobilurin besides having a fungicide effect can promote physiologic benefits to the plants. However, this effect on banana plants was not studied yet. The objective of the present study was to evaluate the effect of strobirulins on the physiology of banana plantlets. For this purpose, cultivar Grand Naine banana plantlets were transferred to pots containing substrate and kept in a nursery with 50% shading. The experimental design was a completely randomized design with three treatments (water, azoxystrobin and pyraclostrobin) and five replications. The treatments were applied at 15, 30, 45, 60 and 75 days after transplanting at a dose 100 g a. i. ha-1 with manual spray. Plant height, pseudostem diameter, shoot dry matter in strobilurin treated plants were higher than the untreated plants, however, the effect of fungicide treatment was different, being the most pronounced effect of pyraclostrobin compared to azoxystrobin. Plants treated with pyraclostrobin had higher leaf area, nitrate reductase activity and chlorophyll content of leaf total nitrogen than the plants treated with azoxystrobin and water, which did not differ. Strobilurins affect the physiology of the banana plantlets differently, the effect being more pronounced by pyraclostrobin. |

Assim sendo, o presente trabalho teve como objetivo avaliar o efeito de estrobirulinas na fisiologia de mudas de bananeira. Para tal, mudas micropropagadas da cultivar Grand Naine foram repicadas para vasos contendo substrato e mantidas em viveiro a 50% de sombreamento. O delineamento experimental foi inteiramente casualizado, com três tratamentos (água, azoxistrobina e piraclostrobina) e cinco repetições. As estrobirulinas foram aplicadas com pulverizador manual aos 15, 30, 45, 60 e 75 dias após a repicagem, na dose de 100 g i. a. ha-1. A altura da planta, diâmetro do pseudocaule e a massa da matéria seca da parte aérea de plantas tratadas com estrobilurinas foram superiores às de plantas não tratadas. O efeito do tratamento com fungicidas foi diferenciado, sendo mais pronunciado nas plantas tratadas com piraclostrobina do que nas plantas tratadas com azoxistrobina. Plantas tratadas com piraclostrobina apresentaram área foliar, atividade da redutase do nitrato e teor de clorofila a e de nitrogênio total foliar superiores às plantas tratadas com azoxistrobina e água, que não diferiram entre si. As estrobilurinas afetaram a fisiologia das mudas de bananeira, com destaque para a piraclostrobina.UEL2012-04-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/566610.5433/1679-0359.2012v33n1p77Semina: Ciências Agrárias; Vol. 33 No. 1 (2012); 77-86Semina: Ciências Agrárias; v. 33 n. 1 (2012); 77-861679-03591676-546Xreponame:Semina.
