- Brassinosteroid accelerates the growth of Psidium hybrid during acclimatization of seedlings obtained from minicuttings Mariana Barreto de Souza Arantes Claudia Sales Marinho Mara de Menezes de Assis Gomes Raudielle Ferreira dos Santos Sydney Pereira Galvão Giuliana Pulitini Vaz Agrociencias BRS Guaraçá guava rootstock Plant growth regulator Guava rootstocks can be multiplied by minicuttings in environment with a high relative humidity, being necessary an acclimatization period. Certain growth regulators favor the acclimatization, with brassinosteroids being successfully used in other fruit plants. This study aimed to shorten the multiplication time of the BRS Guaraçá hybrid by applying Biobras-16 (BB-16) during the acclimatization of seedlings obtained from minicuttings. The treatments consisted of five BB-16 concentrations (0, 0.1, 0.3, 0.5 and 1.0 mg L-1), applied in a randomized block design, in a split-plot arrangement, with four replications and five seedlings per plot, repeated at two seasons: winter and spring/summer. After 60 days of acclimatization, shoot and root growth indicators increased as a function of the BB-16 application, particularly at concentrations between 0.3 and 0.6 mg L-1. The brassinosteroid can be used to stimulate the growth of BRS Guaraçá seedlings obtained from minicuttings, shortening its production time and improving its seedling quality. 2020 artículo científico 1517-6398 https://www.redalyc.org/articulo.oa?id=253068033045 https://www.redalyc.org/journal/2530/253068033045/ https://www.redalyc.org/journal/2530/253068033045/html/ https://www.redalyc.org/journal/2530/253068033045/253068033045.epub https://www.redalyc.org/journal/2530/253068033045/movil https://doi.org/10.1590/1983-40632020v5064743 en http://www.redalyc.org/revista.oa?id=2530 Pesquisa Agropecuária Tropical application/pdf Universidade Federal de Goiás Pesquisa Agropecuária Tropical (Brasil) Vol.50
