“…There was no significant difference regarding the increase in doses used for germination variable (Table 2). These results are in agreement with those found by Ohse et al (2012), by concluding that the zinc doses applied via seed treatment did not affect the germination of seeds of wheat cultivars. Also Funguetto et al (2010), working with rice seeds coated with zinc sulfate, found no differences in germination.…”

The physiological seed quality is a major factor affecting the culture performance and is related to genetic attributes, physical, physiological and seed sanitary. Thus, the objective was to evaluate the physiological potential of seeds of three white oat cultivars treated with zinc. The experiment was conducted in the seed analysis laboratory of the Federal University of Santa Maria campus Frederico Westphalen-RS in September 2014. Was used the completely randomized design, with the treatments distributed in a factorial 3 x 5, being three white oat cultivars (Taura, Guria and Fapa 43) and five doses of the product Teprosyn™ Zn (0, 5, 10, 15 and 20 mL kg -1 seed), with four repetitions of 100 seeds. The physiological quality of treated seeds was evaluated by the germination test, first count, length of radicle, cold test and accelerated aging test. The germination of the seeds of the cultivars Guria, Taura and Fapa 43 is not affected for doses of zinc up to 20 mg kg -1 of seed. The dose of 10 mL kg -1 seed provides the best results for culture, with a significant increase on its vigor, differently among cultivars, through the increment in root length of the cultivars Guria and Fapa 43 and accelerated aging for the cultivars Taura and Fapa 43. The cultivar Taura showed the highest physiological potential, since has obtained the highest germination values, and greater vigor in the cold tests and radicle length.Additional keywords: Avena sativa L.; micronutrient; seed treatment. ResumoA qualidade fisiológica das sementes é um dos principais fatores que afetam o desempenho da cultura e está relacionada aos atributos genéticos, físicos, fisiológicos e sanitários das sementes. Assim, objetivou-se avaliar o potencial fisiológico de sementes de três cultivares de aveia-branca tratadas com zinco. O experimento foi conduzido no laboratório de análise de sementes, da Universidade Federal de Santa Maria, Câmpus de Frederico Westphalen -RS, em setembro de 2014. Utilizou-se o delineamento inteiramente casualizado, com os tratamentos distribuídos em esquema fatorial 3 x 5, sendo três cultivares de aveia-branca (Taura, Guria e Fapa 43) e cinco doses do produto Teprosyn™ Zn (0; 5; 10; 15 e 20 mL kg -1 de semente), com quatro repetições de 100 sementes. A qualidade fisiológica das sementes tratadas foi avaliada pelos testes de germinação, primeira contagem, comprimento de radícula, teste de frio e teste de envelhecimento acelerado. A germinação das sementes das cultivares Guria, Taura e Fapa 43 não é afetada por doses de zinco até 20 mg kg -1 de semente. A dose de 10 mL kg -1 de sementes proporciona os melhores resultados para a cultura, com aumento significativo em seu vigor, de forma diferente entre as cultivares, através do incremento no comprimento radicular das cultivares Guria e Fapa 43, e no envelhecimento acelerado para as cultivares Taura e Fapa 43. A cultivar Taura apresentou o maior potencial fisiológico, uma vez que obteve os maiores valores de germinação, bem como maior vigor nos testes de frio e no comprimento radicu...

“…In relation to the comparison between two cultivars, it is a common approach in experiments that evaluate the performance of seeds subjected to a treatment with nutrients. Several surveys have been conducted in this way, assessing several varieties and their responses to the application of nutrients -such as the works by Tavares et al with barley seeds 43 and rice 44 , the one by Ohse, Cubis 45 with wheat seeds or that by Queiroga, de Queiroz Castro 46 with cotton seeds, to name a fewand significant differences between cultivars were also found, as in the study reported herein.…”

“…The higher percentage of zinc present in micronutrient 1 may have contributed to these results. Ohse et al (2012) observed a 31.63% increase in shoot fresh mass of corn plants submitted to seeds treatment with 0.86 g.kg -1 of Zn. These same authors observed a decreasing in root fresh phytomass with the increase in zinc doses, suggesting a probable toxicity due to the excess of the micronutrient.…”

-In the sowing process, the technique of seed treatment may assist in maintaining crop yield potential. This present study aimed to assess how wheat seed treatment with two different sources of micronutrients, combined with fungicide + insecticide protective treatment and coating with liquid polymer, may impact its vegetative development and grain production. Wheat seeds of cultivar Tec Vigore were subjected to three different treatments using micronutrient containing zinc: no micronutrient, micronutrient 1 (1% Mn, 0.1% Mo, 10% Zn); micronutrient 2 (0.3% B, 0.3% Co; 3% Zn), where micronutrient treatments were combined with different protective treatments used for seed treatment: untreated seeds, polymer (Color seed He), fungicide (Vitavax® Thiram 200 SC) + insecticide (Cruiser® 350 FS) and combination of polymer + fungicide + insecticide. We assessed parameters related to crop development, such as seedling emergence, dry matter of root and shoot, tillers, and for physiological maturity, we assessed grain yield and hectoliter weight. Seed treatment with micronutrients, polymer, fungicide + insecticide and combinations thereof does not reduce emergence and may increase seedling stand, but without influencing wheat grain yield.Index terms: fungicide, insecticide, micronutrient, polymer.Tratamento de sementes e sua influência no potencial produtivo da cultura do trigo RESUMO -No processo de semeadura, a técnica do tratamento de sementes pode auxiliar na manutenção do potencial produtivo. Objetivou-se com esse trabalho avaliar a influência do tratamento de sementes de trigo com duas diferentes fontes de micronutrientes, combinadas aos tratamentos protetores fungicida + inseticida e recobrimento com polímero líquido, no desenvolvimento vegetativo e na produção de grãos. As sementes de trigo, cultivar Tec Vigore, foram submetidas a três diferentes tratamentos utilizando micronutrientes contendo zinco: sem micronutriente, micronutriente 1 (1% Mn; 0,1% Mo; 10% Zn); micronutriente 2 (0,3% B; 0,3% Co; 3% Zn), sendo os tratamentos micronutrientes combinados com diferentes tratamentos protetores utilizados no tratamento de sementes: sementes sem tratamento, polímero (Color seed He), fungicida (Vitavax® Thiram 200 SC) + inseticida (Cruiser®350 FS) e polímero + fungicida + inseticida. Foram avaliados parâmetros relacionados ao desenvolvimento da cultura como emergência de plântulas, massa seca de raiz e parte aérea, perfilhos, e na maturação fisiológica avaliou-se o rendimento de grãos e o peso do hectolitro. O tratamento de sementes com micronutrientes, polímero, fungicida + inseticida e suas combinações não reduz a emergência e pode aumentar o estande de plântulas, mas sem efeitos na produtividade de grãos de trigo.Termos para indexação: fungicida, inseticida, micronutriente, polímero.
