Abstract

INCORPORAÇÃO DE MICRORGANISMOS, AMINOÁCIDOS, MICRONUTRIENTES E REGULADORES DE CRESCIMENTO EM SEMENTES DE ALFACE PELA TÉCNICA DE PELICULIZAÇÃO 1RESUMO -A peliculização é uma tecnologia que permite, dentre outros usos, a inoculação de microrganismos e a incorporação de aditivos às sementes, sem mudança no seu tamanho ou forma e é uma estratégia para garantir alto potencial de emergência em campo, Termos para indexação: Lactuca sativa, revestimento, microbiolização. INCORPORATION OF MICROORGANISM, AMINO ACIDS, MICRONUTRIENTS AND GROWTH REGULATORS IN LETTUCE SEED THROUGH THE COATING TECHNIQUEABSTRACT -Seed coating is a technology that allows incorporation of additive to the seeds, without change its size or form. The coating technique is a strategy that guarantees high seedling emergence in the field, gain in productivity and better aggregation of agricultural inputs to the seeds. Thus, this study had the objective of evaluating the effect of the incorporation of antagonistic microorganisms, mycorrhiza, amino acids, micronutrients and growth regulators through the seed coating technique on the quality of lettuce seeds. The seeds were coated with two types of polymer that were applied together with antagonistic microorganisms (Trichoderma viride, Trichoderma polysporhum, Trichoderma stromaticum, Beauveria bassiana, Metarhizium anisopliae), mycorrhiza, amino acids, micronutrients and growth regulators according to the methodology proposed by the manufacturer. The germination percentage and emergence, the emergence speed index, the number of plants, the dry mass of aerial and root parts and the height of the seedlings were evaluated. Microbiolization of the seeds with the mixture of microorganisms

Physiological traits of the initial growth in rainfed rice plants in response to seed treatment with micronutrients

“…Similar data for shoot dry matter of plants originated both from treated and non-treated seeds were obtained by Diniz et al (2006).…”

Sweet pepper seed responses to inoculation with microorganisms and coating with micronutrients, aminoacids and plant growth regulators

“…As for root dry matter, the best results were obtained for the plant growth regulator treatment (5 mL kg -1 of seeds), which differed from micronutrients (200 g kg -1 of seeds) and aminoacids + Zn treatments (10 mL kg -1 of seeds) (Table 3). Diniz et al (2006) verified that the epithelization of lettuce seeds with vegetal regulator and aminoacids + Zn and the inoculation with Trichoderma viride increase the emergency of the seedlings. Diniz et al (2007) concluded that the vegetal regulators increase the speed of seedling emergency index of when incorporated to the lettuce seeds mL kg -1 between the 20 mL kg -1 and 30 mL kg -1 doses per seeds and the enrichment of these seeds with aminoacids did not affect seed germination, seedling emergency and the speed of seedling emergency index.…”

Efeito Da Pré-Embebição De Sementes De Alface Em Solução Bioestimulante

“…Efeito positivo do uso do bioestimulante também foi obtido para o comprimento da raíz primária, que pode ser notado pelo decréscimo da relação parte aérea/raíz a partir da dose de 15mL.L -1 do produto. Albuquerque et al (2009) observaram um aumento na massa seca das raízes das mudas de alface quando as sementes foram revestidas com o Stimulate®, bem como Diniz (2005) que encontrou resultados similares para raízes de mudas de pimentão.…”
