Resumo: | For strawberry cultivation in Brazil, producers are dependent on imported seedlings. An alternative strategy to reduce this dependence is the use of seedlings obtained from nursery plants grown in a protected environment. However, as these seedlings are produced in the summer and planted at the end of this season or the spring of the following year, it is necessary to control growth to reduce the energy costs of the plants. The objective of this study was to evaluate the effect of different concentrations and periods of application of proexadione calcium (ProCa) on growth control of strawberry seedlings. The experiment was carried out in a greenhouse with seedlings of the cultivars ‘Aromas’ and ‘Camarosa’, produced by rooting stolons and kept in polystyrene trays of 72 cells in a substrate of carbonized rice husk. The experimental design was completely randomized, with a 4 × 2 factorial scheme (4 concentrations of ProCa: 0, 100, 200, and 400 mg L-1 × 2 periods of application: at 20 and 30 days after the planting period of rooting stolon). Plant survival, crown diameter, petiole length, total leaf area, specific leaf area, chlorophyll concentration, and dry mass of the crown and shoot were evaluated. The application of ProCa at 20 days after the planting period of the rooting stolon at the concentrations of 200 and 400 mg L-1 favored the reduction of petiole length in plants of ‘Aromas’ strawberry and total leaf aerial in ‘Camarosa’ strawberry. The application of ProCa from the concentration of 100 mg L-1 reduced the vegetative growth of ‘Aromas’ and ‘Camarosa’ strawberry seedlings cultivated in substrate. |

Com intuito de reduzir essa dependência, uma das alternativas é o uso de mudas obtidas de plantas matrizes cultivadas em ambiente protegido. Porém, como essas mudas são produzidas no verão e plantadas no final desta estação ou no outono do ano seguinte, é necessário controlar o crescimento para diminuir os gastos energéticos das plantas. Objetivou-se com o trabalho avaliar o efeito de diferentes concentrações e épocas de aplicação de proexadione cálcio (ProCa) no controle de crescimento de mudas de morangueiro com torrão. O experimento foi realizado em casa de vegetação com mudas das cultivares Aromas e Camarosa, produzidas por enraizamento de estolões e mantidas em bandejas de poliestireno de 72 células em substrato casca de arroz carbonizada. O delineamento experimental utilizado foi inteiramente casualizado, com esquema fatorial 4x2 (4 concentrações de ProCa: 0, 100, 200 e 400 mg L-1 x 2 épocas de aplicação: aos 20 e aos 30 dias após o período de plantio do estolão para enraizamento). Avaliaram-se nas mudas: sobrevivência de plantas, diâmetro de coroa, comprimento de pecíolo, área foliar total, área foliar específica, concentração de clorofila e massa seca da coroa e da parte aérea. A aplicação de ProCa aos 20 dias após o período de plantio do estolão para enraizamento nas concentrações de 200 e 400 mg L-1 favorece a redução do comprimento do pecíolo em morangueiro ‘Aromas’ e a aérea foliar total em morangueiro ‘Camarosa’. A aplicação de ProCa a partir da concentração de 100 mg L-1 reduz o crescimento vegetativo de mudas de morangueiro ‘Aromas’ e ‘Camarosa’ cultivadas em substrato.UEL2018-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpesquisaapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3129610.5433/1679-0359.2018v39n5p1937Semina: Ciências Agrárias; Vol. 39 No. 5 (2018); 1937-1944Semina: Ciências Agrárias; v. 39 n. 5 (2018); 1937-19441679-03591676-546Xreponame:Semina.
