Resumo:  This study was conducted to evaluate the effects of planting depth and breaking apical dominance on cutting of red pitaya Hylocereus undatus (Haw.) Britton & Rose. The experiment was conducted in a randomized block design with four replications in a 2x3 factorial, with two kinds of cuttings (with or without apical dominance), cutting not sectioned and sectioned at 5 cm from the upper portion, and three planting depths (1.0, 5.0, and 10.0 cm) and each plot consisted of ten 20 cm long cuttings. After 60 days of planting, counts of the number of shoots were began weekly and 90 days after planting survival rooting, number and length of shoots, dry weight of shoots and root dry mass were evaluated. Data were subjected to analysis of variance and polynomial regression at 5% significance level. The percentage of rooting and the survival were 100% in all treatments. With increasing depth of planting it was observed linear reduction in numbers of shoots, dry weight of shoot and root dry mass. The cladodes with apical dominance had longer shoots. The planting of red pitaya cuttings at 1 cm of planting depth with apical dominance is more suited to the production of nursery plants.

Britton & Rose. O experimento foi instalado no delineamento em blocos casualizados, com quatro repetições no esquema fatorial 2x3, sendo dois tipos de estacas (com e sem dominância apical), estacas não seccionadas e seccionadas a 5 cm da porção superior, e três profundidades de plantio (1,0; 5,0; 10,0 cm) e cada parcela foi constituída de dez estacas com 20 cm de comprimento. Após 60 dias do plantio, foram iniciadas as avaliações semanais do número de brotações e aos 90 dias após o plantio foram avaliados sobrevivência, enraizamento, número e comprimento de brotações, massa seca das brotações, e massa seca das raízes. Os dados foram submetidos à análise de variância e à regressão polinomial a 5% de significância. O percentual de enraizamento e a sobrevivência das estacas usadas no experimento foi 100% em todos os tratamentos. Com o aumento da profundidade de plantio foi observado redução linear em: número de brotações, massa seca da parte aérea e a massa seca da raiz. Os cladódios com dominância apical obtiveram comprimento de brotações superior. O plantio de estacas de pitaia vermelha na profundidade de 1 cm e com dominância apical é mais satisfatório para a produção de mudas.UEL2012-12-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de CampoPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/797210.5433/1679-0359.2012v33n6p2091Semina: Ciências Agrárias; Vol. 33 No. 6 (2012); 2091-2098Semina: Ciências Agrárias; v. 33 n. 6 (2012); 2091-20981679-03591676-546Xreponame:Semina.
