| description | The aim of this study was to evaluate the action of plant biostimulant Stimulate® on early growth and flowering of sunflower (Helianthus annuus L.). The experiment was conducted in the greenhouse and in the laboratory of the Center for Environmental and Biological Agricultural Sciences (CCAAB), Federal University of Bahia State Recôncavo. It was used sunflower seeds, cultivar Catissol 01 and biostimulant plant Stimulate® (0,009 % kinetin, 0,005 % butyric acid and 0,005 % gibberellic acid ). The treatments were: T1 = control (plants originated from seeds without any treatment - CT), T2 = plants originated from seeds pre-soaked in water (EA), T3 = plants originated from seeds pre-soaked in solution Stimulate® (ES), T4 = plants originated from seeds pre-soaked in water and sprayed with water (E+P/A), T5 = plants sprayed with water (PA), T6 = plants originated from seeds pre-soaked in solution Stimulate® (4 mL L-1) and then sprayed with solution Stimulate® (E+P/S), T7 = plants treated with Stimulate® solution (PS). The sowing was carried out in polyethylene bags (capacity 2 kg) containing commercial substrate. At 9, 13 and 16 days after sowing (DAS) foliar sprays were performed. At 32 DAS it was evaluated: the total length of plant and total dry mass, and at 30 and 32 DAS compared the phenological stages of plants. The design was completely randomized design with seven treatments and eight repetitions. Data were subjected to analysis of variance and treatment means, Tukey’s test at 5 % probability error. The combination of pre-soaking seeds, plus the subsequent foliar spraying with Stimulate® (E+P/S) was more efficient on growth and promoted earlier flowering sunflower. |

O objetivo desse trabalho foi avaliar a ação do bioestimulante vegetal Stimulate® no crescimento inicial eflorescimento do girassol (Helianthus annuus L.). O experimento foi conduzido em casa de vegetação e nolaboratório do Centro de Ciências Agrárias Ambientais e Biológicas (CCAAB) da Universidade Federal doRecôncavo da Bahia. Utilizaram-se sementes de girassol, variedade Catissol 01, e o bioestimulante vegetalStimulate® (0,009% de cinetina, 0,005% de ácido indolbutírico e 0,005% de ácido giberélico). Os tratamentosforam: T1 = controle (plantas oriundas de sementes sem nenhum tratamento - CT), T2 = plantas oriundas desementes pré-embebidas em água (EA), T3 = plantas oriundas de sementes pré-embebidas em soluçãode Stimulate® (4 mL L-1)(ES), T4 = plantas oriundas de sementes pré-embebidas em água e posteriormentepulverizadas com água (E+P/A), T5 = plantas pulverizadas com água (PA), T6 = plantas oriundas de sementespré-embebidas em solução de Stimulate® (4 mL L-1) e posteriormente pulverizadas com solução de Stimulate®(4 mL L-1) (E+P/S), T7 = plantas pulverizadas com solução de Stimulate® (PS). A semadura foi realizada emsacos de polietileno (capacidade 2 kg), contendo substrato comercial. Aos 9, 13 e 16 dias após a semeadura(DAS) foram realizadas as pulverizações foliares. Aos 32 DAS avaliou-se: o comprimento total de plantas emassa seca total, e aos 30 e 32 DAS comparou-se os estádios fenológicos das plantas. O delineamentoutilizado foi inteiramente casualizado com sete tratamentos e oito repetições. Os dados foram submetidosà análise de variância e as médias dos tratamentos, ao teste de Tukey ao nível de 5% de probabilidade. Acombinação da pré-embebição de sementes, mais a posterior pulverização foliar com Stimulate® (E+P/S) foimais eficiente no crescimento e promoveu o florescimento precoce do girassol. 2012-12-19 2022-03-21T20:06:57Z 2022-03-21T20:06:57Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://comunicatascientiae.com.br/comunicata/article/view/115 10.14295/cs.v3i4.115 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/77532 por https://comunicatascientiae.com.br/comunicata/article/view/115/142 application/pdf Federal University of Piauí Comunicata Scientiae; Vol. 3 No. 4 (2012); 310-315 Comunicata Scientiae; v. 3 n. 4 (2012); 310-315 2177-5133 2176-9079 |
