“…Na germinação de sementes e emergência de plântulas, as giberelinas atuam tanto na degradação do endosperma que envolve o embrião como na ativação enzimática e na mobilização de reservas energéticas que resultam no crescimento inicial e, em algumas espécies, pode substituir o efeito da luz na germinação (BRADFORD, 2004). São poucos os estudos avaliando os efeitos de GA sobre germinação de Passiflora (ATAÍDE et al, 2006;DELANOY et al, 2006;FERRARI et al, 2008;FERREIRA et al, 2005;OLIVEIRA et al, 2005).

“…Essas variáveis em conjunto tornaram o crescimento vegetativo das plantas tratadas mais vigoroso. A aplicação de giberelina altera uma série de caracteres produtivos, como o crescimento vegetativo, a densidade da madeira, o teor de lignina e o diâmetro da fibra de plantas de Eucalyptus (ALONI, 1979;BIEMELT et al, 2004;SANTOS, 2005;PEREIRA et al, 2011), no entanto o intenso alongamento do caule elevando a altura das plantas é o principal efeito da aplicação de giberelina (HIGASHI et al, 2002;OLIVEIRA et al, 2005).…”

RESUMO -A competitividade do setor florestal brasileiro, fruto das condições climáticas e tecnologia empregada, faz que o país ocupe posição de destaque no cenário mundial. Apesar do elevado crescimento brasileiro no setor florestal, é necessário o desenvolvimento de pesquisas que proporcionem aumento de produtividade. Este estudo objetivou avaliar o efeito fisiológico da aplicação de diferentes concentrações de giberelina (GA 3 ) no acúmulo de biomassa do híbrido de Eucalyptus grandis x Eucalyptus urophylla "E. urograndis GG 100" e, também, verificar o efeito da aplicação de hormônio sobre a incidência de Rhizoctonia sp. e sobre efeito antixenose (não preferência) ao corte de folhas pela formiga-cortadeira Atta sexdens rubropilosa. O experimento foi conduzido em bancada a pleno sol, seguindo o delineamento inteiramente casualizado com cinco tratamentos e seis repetições. Mudas clonadas de E. urograndis GG 100, com 120 dias de idade, cultivadas sob bancada a pleno sol em vasos de 12 L, com substrato à base de subsolo, areia e esterco foram tratados com 50 mL de GA 3 , nas seguintes concentrações: 0; 50; 100; 150; e 200 mg L ANALYSIS OF Rhizoctonia SP.

“…This effect may be related to the composition of Bio B, which by When treating other seaweed, it must be in its composition a higher proportion of gibberellins, which according to Taiz and Zeiger [9], promotes the cell division and stretching. The employment of combination of plant regulators (gibberellin and cytokine) in the development of seedlings of passion fruit allows an increase in the values diameters, which in practical terms means easier grafting [10].…”

In the Brazil, the cultivation of pomegranate aroused interest in several producers of fruit, especially in the northeast. The objective of this study was to test the efficiency of the best dose of the extract of seaweed in the development of pomegranate trees seedlings. The experiment was conducted in a greenhouse at the Federal Rural University of Semi-Arid (UFERSA), Mossoro, RN. In the experiment, was used a randomized complete block design (RBD) with five doses (0, 2, 4, 6 and 8 ml L -1 ) of the seaweed extract and six replications; each experimental unit was composed of five plants. The application of bio-stimulant doses were started at 7 days after transplanting, and the extract applied in seven-day intervals with a syringe, pouring 15 ml of solution near the base of each plant until the end of the experiment. At 120 days after sowing the characteristics were evaluated: shoot length, root and total (cm); number of sheets (unit/plant), lap diameter (mm), dry mass of the stalk, the leaf, the shoot, root system and total (g). For further growth, dry biomass yield and better quality of pomegranate trees seedlings in nurseries, it was observed that the dose of 4.0 mL of biostimulants, promoted greater seedling growth.Due to the lack of data on the development and establishment of pomegranate culture in Brazil, there is a need for studies to domesticate a species such as the climatic conditions of the region.And to meet the new demands, it is necessary to expand the production area and, as such, to produce uniform and vigorous quality seedlings (PAIVA., et al. 2015). In this sense, a seedling propagation and acquisition phase is fundamental for the establishment of the crop in the field, since low substrate fertility and plant nutrition are some of the most limiting problems and can be corrected with the use of soil extraction. seaweed as a biostimulant [1].In Brazil, the use of seaweed in commercial crops, in general, is in full expansion requiring more accurate information regarding its proper use. These synthesize plant hormones and there are products based on macroalgae extracts, which are commercially used as biostimulants to increase agricultural production. As an example, we can mention commercial products based on Ascophyllum nodosum and Lithothamnium, which, due to their action similar to plant hormones, have been used for foliar or soil applications, including organic agriculture [2].
