Resumo: | 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.

Alguns reguladores de crescimento favorecem a aclimatação, sendo os brassinosteroides utilizados com sucesso em outras frutíferas. Objetivou-se reduzir o tempo de multiplicação do híbrido BRS Guaraçá com aplicações de Biobras-16 (BB-16) na fase de aclimatação de mudas obtidas por miniestaquia. Os tratamentos consistiram de cinco concentrações de BB-16 (0; 0,1; 0,3; 0,5; e 1,0 mg L-1), aplicadas em delineamento experimental com blocos casualizados, em esquema de parcelas subdivididas, com quatro repetições e cinco mudas por parcela, repetidos em duas épocas do ano: inverno e primavera/verão. Ao final de sessenta dias de aclimatação, indicadores de crescimento da parte aérea e raízes tiveram incrementos em função da aplicação de BB-16, notadamente nas concentrações entre 0,3 e 0,6 mg L-1. O brassinosteroide pode ser utilizado para estimular o crescimento de mudas de BRS Guaraçá oriundas de miniestaquia, reduzindo o seu tempo de produção e incrementando sua qualidade.
