“…O ácido indolbutírico (auxina), presente na composição do bioestimulante é responsável pelo alongamento da parede celular (essa é a resposta inicial dos tecidos vegetais às auxinas) e a cinetina (citocinina) participa ativamente dos processos de divisão e diferenciação celular (TAIZ; ZEIGER, 2009), além de estimular a divisão celular; a mistura de auxinas e de citocininas induz o início da diferenciação celular e dessa forma o bioestimulante pode agir no crescimento e desenvolvimento foliar (VIEIRA; CASTRO, 2001). Contudo, a resposta das plantas ao bioestimulante que contem estas substâncias pode variar em função de diversos fatores (ALBRECHT et al, 2012). Tabela 3.…”

“…A aplicação do produto em mais de uma época (TS+V 4 Abrantes et al (2011) também constataram que aplicação do bioestimulante no estádio reprodutivo (R 5 ) porporcionou aumento no número de grãos por planta e produtividade de grãos do feijoeiro. Tais resultados indicam que a resposta da cultura a aplicação do bioestimulante depende não só da dose e época/forma de aplicação, mas também pode ser influenciada por outros fatores, como condição de cultivo e estresses aos quais as plantas são submetidas no momento da aplicação e nas fases subsequentes, como relatado por Alleoni, Bosqueiro e Rossi (2000) e Albrecht et al (2012).…”

ResumoA utilização de bioestimulantes pode alterar o desenvolvimento e o crescimento vegetal, porém, a ação dos mesmos pode ser variável conforme o estádio de desenvolvimento da planta. Objetivou-se avaliar o efeito de formas e épocas de aplicação de um bioestimulante (citocinina, ácido indolbutírico e ácido giberélico) na nodulação, alguns aspectos bioquímicos, crescimento e produtividade do feijoeiro cultivar Pérola. Os tratamentos foram: Testemunha (sem aplicação); TS -250 mL ha -1 em tratamento de semente (TS); V 4 -250 mL ha -1 via pulverização foliar em V 4 ; R 5 -250 mL ha -1 via pulverização foliar em R 5 ; TS+V 4 -250 mL ha -1 em TS + 250 mL ha -1 em V 4 ; TS+R 5 -250 mL ha -1 em TS + 250 mL ha -1 em R 5 ; V 4 +R 5 -250 mL ha -1 em V 4 + 250 mL ha -1 em R 5 e TS+V 4 +R 5 -250 mL ha -1 em TS + 250 mL ha -1 em V 4 + 250 mL ha -1 em R 5 . A aplicação do bioestimulante via foliar na fase vegetativa (V 4 ) ou início da reprodutiva (R 5 ) proporciona incrementos na nodulação, no crescimento radicular, no conteúdo de açúcares solúveis e aminoácidos totais e na atividade da nitrato redutase, porém, não interfe no crescimento da parte aérea e na produtividade da cultura do feijão. Palavras-chave: Phaseolus vulgaris, regulador vegetal, nitrato redutase, crescimento radicular AbstractThe use of biostimulants can alter plant growth and development, but the action of they may be varied according to the stage of development of the plant. The aim was to evaluate the effects of forms and times of a biostimulant (cytokinin, indolebutyric acid, and gibberellic acid) application on nodulation, some biochemical aspects, growth and yield of common bean cultivar Pérola. The treatments were: Control (without application); TS -250 mL ha -1 seed treatment; V 4 -250 mL ha -1 foliar spray in V 4 stage; R 5 -250 mL ha -1 foliar spray in R 5 stage; TS+V 4 -250 mL ha -1 in TS + 250 mL ha -1 in V 4 ; TS+R 5 -250 mL ha -1 in TS + 250 mL ha -1 in R 5 ; V 4 +R 5 -250 mL ha -1 in V 4 + 250 mL ha -1 in R 5 , and TS+V 4 +R 5 -250 mL ha -1 in TS + 250 mL ha -1 in V 4 + 250 mL ha -1 in R 5 .The foliar biostimulant application in the vegetative (V 4 ) or early reproductive phase (R 5 ) increases nodulation, root growth, content of soluble sugars, content of total amino acid and nitrate reductase activity, however, does not interfere with shoot growth and grain yield of common bean.

“…These authors found that the effects of the biostimulant on plants change under stress conditions, which indicates that a set of ecophysiological factors, together or separately, may interfere with the performance of bioregulators (Albrecht, Braccini, Scapim, Ávila, & Albrecht, 2012).…”

<b>Gherkin cultivation in saline medium using seeds treated with a biostimulant

ABSTRACT. The objective of this study was to evaluate the effects of a biostimulant on gherkin seeds, cultivar Liso de Calcutá, under conditions of salt stress. A split-plot experimental design with five replications was used; the main plot was represented by two levels of irrigation water salinity (0.5 and 3.5 dS m -1 ), and the subplot was composed of five biostimulant doses applied as a seed treatment (0, 5, 10, 15, and 20 mL kg -1). The following variables were evaluated: the number of leaves; number of branches; length of the largest branch; leaf, stem, fruit and total dry matter; number of fruits; average fruit weight; and fruit production. The values of all analyzed variables decreased with an increase in irrigation water salinity regardless of the biostimulant dose, but in the absence of salt stress, biostimulant use led to an increase in the number of leaves and branches, the length of the largest branch and biomass accumulation. Biostimulation was not effective in reducing the effects of salinity on gherkin production, but it increased fruit production regardless of the salinity level.

“…The use of plant growth regulators as agronomic technique to optimize production in several crops has increased in the last years (Klahold et al 2006). Many authors studied the application effects of Stimulate ® in soybeans and noticed increase in the number of pod, grains (Klahold et al 2006, Batista-Filho et al 2013) and productivity (Klahold et al, 2006;Batista-filho et al, 2013;Bertolin et al, 2010;Albrecht et al, 2012). However, Klahold et al (2006) and Batista-Filho et al (2013) reported that the grain weight was lower.…”

Several studies have proved the efficiency of the application of biostimulant to increase soybean yield. However, little is known about the influence of these products on the seeds quality coming from cultivation with its application. Thus, the objective of this study was to evaluate the physiological quality of soybean seeds coming from the cultivation in function of periods and doses of biostimulant application. The study was performed in two phases. The first phase was carried out in field condition, at the Experimental Station of MT Foundation during the 2012/13 crop. The experimental design was a randomized block with four replications and nine treatments arranged in an incomplete factorial scheme 2x4+1, i.e. two periods of foliar application (V 5 and R 2 ) and four doses of biostimulant (250, 500, 750 and 1,000 mL ha -1 ) and one control treatment (without application of product). The second phase of the study was performed in the Seed Analysis Laboratory. In the cold test, the treatments with application of biostimulant in V 5 with 750 mL ha -1 and in the R2 with 250, 500 and 1,000 mL ha -1 presented higher percentage of normal seedlings than the control. The fresh biomass and accelerated aging also presented positive results. However, most of tests did not affect seed physiological quality. It was concluded that the foliar application of biostimulant with doses of 0, 250, 500, 750 and 1,000 mL ha -1 in V 5 and R 2 on soybean plants does not influence the quality of the seeds produced.
