dc.descriptionIt aimed to evaluate the effects of gibberellin action on the growth of yellow passion fruit, under foliar spray in different solutions of GA3. The experiment was conducted at the Laboratory of Plant Physiology and in the greenhouse of the Center for Agricultural, Environmental and Biological Sciences of UFRB. Seeds of yellow passion fruit (Passiflora edulis Sims f. flavicarpa Deg) and growth regulator gibberellin (4% GA3), at doses 0.5; 1.0; 2.0; 4.0 mL of gibberellin per liter of solution and distilled water as control. The seeds were sown in polyethylene bags with 15cm wide x 20cm long (capacity 2 kg) containing washed sand. It was initially placed four seeds per bag in each repetition. At 15 days after sowing (DAS) it was held thinning leaving one plant per bag. The experimental design was completely randomized with five treatments and four replications. At 40 DAS, plants were submitted to spraying with solutions of gibberellin for seven consecutive days. At 70 DAS it were recorded: length of root, stem and total (cm), number of leaves, dry weight of root, leaf, stem and total plant (g). Concentrations in the range between 90 and 100 mg GA3 L-1, given by foliar sprays, promote significant growth in stem length. The plant regulator, for concentrations in the range of  78 and 92 mg GA3 L-1,  increases the dry weight of root, stem and total passion fruit plant.en-US
dc.descriptionObjetivou-se avaliar os efeitos da ação da giberelina no crescimento inicial de plantas de maracujazeiro, sob pulverização foliar, em diferentes soluções de GA3. O experimento foi conduzido no Laboratório de Fisiologia Vegetal e em casa de vegetação do Centro de Ciências Agrárias, Ambientais e Biológicas da UFRB. Foram utilizadas sementes de maracujá amarelo (Passiflora edulis Sims f. flavicarpa Deg) e o regulador de crescimento giberelina (4% GA3), nas dosagens 0,5; 1,0; 2,0; 4,0 mL de giberelina por litro de solução e água destilada como testemunha. As sementes foram semeadas em sacos de polietileno preto de 15cm de largura x 20cm de comprimento (capacidade 2 kg), contendo areia lavada. Inicialmente foram colocadas quatro sementes por saco em cada repetição. Aos 15 dias após a semeadura (DAS) realizou-se o desbaste deixando uma planta por saco. O delineamento experimental foi inteiramente casualizado com cinco tratamentos e quatro repetições. Aos 40 DAS, as plantas foram submetidas a pulverizações com as soluções de giberelina durante sete dias consecutivos. Aos 70 DAS registraram-se: comprimento da raiz, do caule e total (cm), o número de folhas, a massa seca de raiz, folha, caule e total das plantas (g). Concentrações no intervalo entre 90 e 100 mg GA3 L-1, ministrado via pulverização foliar, promovem crescimento expressivo no comprimento do caule. O regulador vegetal, para concentrações no intervalo de 78 e 92 mg GA3 L-1,  incrementa a massa seca de raiz, caule e total em plantas de maracujazeiro amarelo.   Initial growth of the yellow passion plants submitted to gibberellinAbstractIt aimed to evaluate the effects of gibberellin action on the growth of yellow passion fruit, under foliar spray in different solutions of GA3.
