description Studies involving plant growth-promoting bacteria are attracting increasing attention in the agricultural sector due to their potential to improve growth and production, and to protect plants from biotic and abiotic stresses. The present study aimed to evaluate the effects of three species of plant growth-promoting bacteria (Bacillus subtilis, Priestia megaterium, and Priestia aryabhattai) on the growth and morphological and biochemical aspects of Gossypium hirsutum L. (cotton) seedlings. The experiment was conducted in a greenhouse with four treatments (one control and three inoculations) and five replications per treatment. The seeds were inoculated by immersion in bacterial suspensions (109CFU/mL) and then sown in pots. The plants were monitored for 60 days. During collection, the plants were measured for the fresh mass of roots and shoots, the height of the shoots, stem diameter, and number of leaves. Leaf samples were collected and used for biochemical analyses. The results obtained showed that seeds treated with P. aryabhattaihad significant improvements in the parameters of fresh mass, plant height, stem diameter, and number of leaves, and in the contents of chlorophyll (a, b, and total), nitrogen, and proteins concerning plants in the control treatment. Plants treated with P. megaterium also achieved improvements in fresh mass, stem diameter, nitrogen, and protein contents. These results indicate the potential of these plant growth-promoting bacteria for use in cotton crops and can be employed in the preparation of biostimulants and biofertilizers.

O presente estudo teve como objetivo avaliar o efeito de três espécies de bactérias promotoras de crescimento de plantas (Bacillus subtilis, Priestia megaterium e Priestia aryabhattai) no crescimento e nos aspectos morfológicos e bioquímicos de plântulas de Gossypium hirsutumL. (algodão). O experimento foi conduzido em casa de vegetação com quatro tratamentos (um controle e três inoculações) e cinco repetições por tratamento. As sementes foram inoculadas por imersão em suspensões bacterianas (109 UFC/mL) e então semeadas em vasos. As plantas foram acompanhadas por 60 dias. Na coleta, as plantas foram mensuradas quanto à massa fresca das raízes e da parte aérea, à altura da parte aérea, ao diâmetro do caule e número de folhas. Amostras foliares foram submetidas às análises bioquímicas. Os resultados obtidos mostraram que sementes tratadas com P. aryabhattai tiveram melhorias significativas nos parâmetros de massa fresca, altura da planta, diâmetro do caule e número de folhas e nos teores de clorofila (a, b e total), nitrogênio e proteínas em relação às plantas do tratamento controle. Plantas tratadas com P. megaterium também obtiveram melhorias na massa fresca, no diâmetro do caule e nos teores de nitrogênio e proteínas. Esses resultados indicam um potencial dessas bactérias promotoras de crescimento de plantas para utilização em culturas do algodão, podendo ser empregadas na elaboração de bioestimulantes e biofertilizantes.Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)2024-05-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/190610.5327/Z2176-94781906Revista Brasileira de Ciências Ambientais; Vol. 59 (2024): RBCIAMB - ISSN 2176-9478; e1906Revista Brasileira de Ciências Ambientais ; v. 59 (2024): RBCIAMB - ISSN 2176-9478; e19062176-94781808-4524reponame:Revista Brasileira de Ciências Ambientais (Online)instname:Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)instacron:ABESenghttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/1906/972https://www.rbciamb.com.br/Publicacoes_RBCIAMB/article/view/1906/1021Copyright (c) 2024 Revista Brasileira de Ciências Ambientais (RBCIAMB)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFarias, Mateus Henrique FreireMelo, Ana Raquel Pereira deFreitas, Elis Marina deLima, Marcos Antônio BarbosaSilveira, Fernando Augusto daFerreira, Éder Galinari2025-01-21T00:06:28Zoai:ojs.www.rbciamb.com.br:article/1906Revistahttp://www.rbciamb.com.br/index.php/Publicacoes_RBCIAMBhttps://www.rbciamb.com.br/Publicacoes_RBCIAMB/oairbciamb@abes-dn.org.br||2176-94781804-4524opendoar:2025-01-21T00:06:28Revista Brasileira de Ciências Ambientais (Online) - Associação Brasileira de Engenharia Sanitária e Ambiental (ABES)false
