| Abstract (English): |
The aim of this work was to evaluate the effect of different cutting lengths, the use of biostimulants and diameter of cuttings on hops vegetative propagation. The work was conducted in a greenhouse at the Center for Agricultural Sciences (CCA) at the Federal University of Santa Catarina (UFSC), in Florianópolis/SC, Brazil, between October 2019 and January 2021. In experiment 1, cuttings with one, two and three buds were tested, with and without application of biostimulant SprintAlga TS® (Biolchim) in Brewer's Gold and Cascade cultivars. In experiment 2, cuttings with diameter of 1.5 cm, 2.5 cm and 3.5 cm were tested for Northern Brewer cultivar. In both experiments, survival, rooting, root length, root quality, number of shoots and shoot length were evaluated. In experiment 1, Cascade had lower survival, rooting and development compared to Brewer's Gold. The use of biostimulant increased survival and rooting rates of both cultivars. For Brewer's Gold the use of biostimulant improved root quality and increased shoot number, root and shoot length. For Brewer's Gold, 3-bud cuttings improved root quality and increased number of shoots. For Cascade, 1-bud cuttings showed the highest survival, rooting and development rates. In experiment 2, the highest rates of survival, rooting and the longest root length were obtained with 1.5 cm diameter cuttings. Larger diameter cuttings (2.5 and 3.5 cm) produced fewer shoots, but longer shoots. [ABSTRACT FROM AUTHOR] |

Objetiva-se com este trabalho avaliar o efeito de diferentes comprimentos e diâmetros de estacas e da utilização de bioestimulantes na propagação vegetativa de lúpulo. O trabalho foi conduzido em uma estufa no Centro de Ciências Agrárias (CCA) da Universidade Federal de Santa Catarina (UFSC), em Florianópolis/SC, Brasil, entre outubro de 2019 e janeiro de 2021. No experimento 1 foram testadas estacas com uma, duas e três gemas, com e sem aplicação do bioestimulante SprintAlga TS® (Biolchim) nas cultivares Brewer's Gold e Cascade. No experimento 2 foram testadas estacas de 1,5 cm, 2,5 cm e 3,5 cm de diâmetro para a cultivar Northern Brewer. Foram avaliados o percentual de sobrevivência, enraizamento, comprimento de raízes, qualidade da raiz, número e comprimento de brotações. No experimento 1 Cascade apresentou menores percentuais de sobrevivência, enraizamento e desenvolvimento. O uso do bioestimulante aumentou a sobrevivência e o enraizamento de ambas as cultivares. Para Brewer's Gold o bioestimulante aumentou a qualidade das raízes, número de brotações, comprimento de raiz e de brotação. Estacas de Brewer's Gold com 3 gemas favoreceram a qualidade das raízes e número de brotações. Estacas de Cascade com 1 gema apresentaram maior percentual de sobrevivência, enraizamento e desenvolvimento. No experimento 2 as estacas de 1,5 cm de diâmetro apresentaram maior sobrevivência, enraizamento e comprimento de raiz. Estacas com 2,5 e 3,5 cm produziram menor número de brotações, mas de maior comprimento. [ABSTRACT FROM AUTHOR] |
