“…There was increases in the shoot dry mass as a function of the biostimulant doses until 0.70 L 100 kg -1 of seeds; from this point, it is observed decrease in the values of this characteristic ( Figure 4). This result ratifies that found for fresh mass, and points out the potential of the biostimulant in increasing nutrient translocation, cell division and multiplication (Bomtempo et al, 2016;Martynenko et al, 2016), and, consequently, the dry mass of the seedling. This morphological change provides characteristics of great interest to farmers, such as resistance to water deficit and extreme temperatures, because plants with higher shoot mass (fresh and dry) tend to endure the lack of soil moisture for longer, before entering a permanent wilting point (Vollet, 2006).…”

“…In order to increase agricultural production, seed germination and seedling emergence must be rapid and uniform (Rajjou et al, 2012). Factors such as low seed quality, uneven planting/fertilization, low soil fertility, and mainly climatic adversities may limit the development of maize seedlings (Bomtempo et al, 2016). Thus, biostimulants would be a strategy to minimize the effects of low seed quality (Klahold et al, 2008), favoring the expression of the genetic potential of plants, promoting hormonal balance, and stimulating the development of the root system (Silva et al, 2008;Castro & Amaral, 2014).…”

Biostimulants are used as a strategy to minimize the effects of climatic adversities by allowing the seedlings to express more strongly their metabolic capacity and to have a greater root system development. The objective was to evaluate the effect of seed treatment with different doses of a biostimulant composed of Ascophyllum nodosum on the agronomic performance of maize seedlings. The experiment was carried out in a randomized block design with five treatments and four replicates, using five doses of the biostimulant, 0,0; 0.25; 0.50; 0.75; and 1.00 liter of product per 100 kg of seeds. The following were evaluated: vigor, fresh mass of roots and shoots, dry mass of roots and shoots, root length, shoot height, and leaf area. The data were submitted to ANOVA and regression analysis to verify the behavior of the characteristics as a function of the biostimulant doses. In the treatment of seeds, these doses provided increases in vigor, shoot height, fresh and dry mass of shoots, and leaf area. The biostimulant derived from the Ascophyllum nodosum extract showed potential use in the treatment of maize seeds, with the doses of 0.50 and 0.75 liters per 100 kg seeds being the most promising for the initial development of maize seedlings.

The objective of this study was to evaluate the agronomic characteristics of corn hybrids short cycle on levels of plant regulator Stimulate® in two periods. The planting was done in field, in the experimental farm of the Mato Grosso do Sul State University. The experimental design was completely randomized, in a factorial scheme (3 × 2 × 2), with four replicates. The treatments consisted of three levels (0, 250 and 500 mL ha-1) of the plant regulator, with two hybrids (30A37PW Morgan and P3646-HY) and two times of application (vegetative stage and reproductive stage). The following averages were evaluated: plant height, number of leaves, tassel weight, tang weight, tang length, leaf weight, number of spikes, stem weight, stem diameter, ear diameter and whole plant weight. The number of leaves, number of spikes and stalk diameter were higher to P3646-HY and the tassel weight was higher to Morgan 30A37PW. The application of growth regulator of the doses of 250 and 500 mL ha-1, divided in the vegetative and reproductive stages, caused a reduction in stem diameter and whole plant weight, and in the other parameters the application in single dose and in divided dose did not affect plant growth. The genotype P3646-HY obtained higher number of leaves, number of spikes and stem diameter than the genotype 30A37PW Morgan, but this presented higher tassel weight.

“…Devido ao crescente aumento da população nos países em desenvolvimento e, consequentemente, a demanda pela elevação dos níveis de produtividade, novas tecnologias vêm sendo desenvolvidas com o objetivo de estimular o crescimento e a produtividade do feijoeiro (ABRANTES et al, 2011). Dentre as tecnologias citam-se os promotores de crescimento, definidos como a mistura de reguladores vegetais, ou de um ou mais reguladores vegetais com outros compostos de natureza química diferente como aminoácidos, nutrientes e vitaminas (CASTRO;VIEIRA, 2001).…”

“…Nas principais culturas como algodão, cana-de-açúcar, trigo e soja, reguladores de crescimento de plantas têm sido comumente usados para reduzir a altura da planta e fornecer maior uniformidade do dossel (NASCIMENTO et al, 2009;ESPÍNDULA et al, 2011). Além disso, os promotores de crescimento favorecem a expressão do potencial genético das plantas mediante alterações nos processos vitais e estruturais, promovem o equilíbrio hormonal e estimulam o desenvolvimento do sistema radicular (CASTRO;VIEIRA, 2001;SILVA et al, 2008).…”

Common bean hasan economic and social relevancefor the Brazilian population. Among the technologies that contribute to high crop yieldare growth promoters. This study objected to determine the growth promoters’effect, applied via seed or via seed and leaf, on the performance of super early common bean, cultivar FC-104, regarding the physiological(gas exchange and nutrient content) and agronomic (yield and itscomponents) indicators. The experimental design was a randomized complete block, with 13 treatments and fourreplicates. The treatments were constituted by the growth promoters (I) MicronutrientsComplex, (II) Leonardite; (III) Micronutrients+ fulvic acids, (IV) Micronutrients+ amino acids; (V) Micronutrients+ Ascophyllum; (VI) Micronutrients+ Eklonya; (VII) N + Zn; (VIII) N + K + amino acids; (IX) Growth regulators; (X) Trichodermaasperellum, (XI) T. asperellum+ Bacillus methylotrophicusand(XII) Peat. Seeds treated with water was considered control treatment(XIII). In treatments IV and XI, the plants had significantly higher stomatal conductance(gs)and number of pods per plant (NVP).In treatment V, theplants presentedhighervalue of leaf phosphorus (P), in both casesin relation to the control.However, there was no significant increase in grain yield of common bean treated with growth promoter
