“…Similarly, the use of these same products also provided in increments of LA values of wheat plants on the grounds of increased doses (maximum dose tested of 3.12 g Zn.kg -1 of seeds and 0.03 g B.kg -1 of seeds) (Tavares et al, 2013b). These results corroborate with those found for plants of oats covered with Zn (at a dose of 3.12 g Zn.kg -1 of seeds) (Oliveira et al, 2014). It is important to highlight that the doses evaluated in the works mentioned are tiny compared to those used in this study.…”

“…However, several authors report that the seed coating with these micronutrients either applied alone or in combination, does not affect the germination (Ohse et al, 2000;Masuthi et al, 2009;Tavares et al, 2013a;Tavares et al, 2013b;Tavares et al, 2013c;Arjmand et al, 2014;Oliveira et al, 2014). However, it is noteworthy that the species used in this study differs from the species evaluated by the authors mentioned and the doses of micronutrients were employed higher than those used for the same.…”

“…Positive results of the seed coating for SDW and RDW with Zn and B were described in rice plants irrigated and dry mass of wheat plants from seeds coated with Zn, SDW of rice plants from seeds coated with Zn, B and Mo and plant dry weight of oats from the covering with Zn (Funguetto, 2007;Tavares et al, 2013b;Tavares et al, 2013a;Oliveira et al, 2014). From the foregoing it was possible to observe that the covering of seeds of cv.…”

“…High productions can be reached with high-quality seeds -inputs responsible for the emergence and uniform establishment of a suitable stand, which consist of basic requirements for a cultivation with a high grain yield potential (Oliveira et al, 2014). Sá (1994) stated that nutrient availability to plants might interfere with seed quality, since such a factor is related to chemical composition, embryo formation, and reserve structures and, then, physiological performance.…”

Trinexapac-ethyl and topdressing nitrogen levels on the productivity and physiological quality of graniferous white oat seeds

et al. 2018

The aim of this study was to evaluate the physiological quality of white oat seeds cultivated under different topdressing N levels combined with the plant growth retardant trinexapac-ethyl in two growing environments. The experiments were carried out in Londrina and Mauá da Serra Municipalities (PR, Brazil) with the cultivar ‘IPR Afrodite’. The experimental design was in randomized blocks, in a 4x2 factorial arrangement, with four replications. Treatments consisted of four N levels (0, 30, 60, and 90 kg.ha-1) combined or not with the plant growth retardant. Seed yield, 1000-seed weight, germination, first germination count, seedling length, seedling dry matter, accelerated aging, electrical conductivity, emergence speed index, and seedling emergence in sand were evaluated. Data were submitted to the analysis of variance and then to the F test and regression analysis up to the second degree (p≤0.05). The application of the plant growth retardant and N topdressing led to an increase in seed productivity in Mauá da Serra. N fertilization reduced seed quality, but this effect can be minimized, not observed or overlapped by the positive effect of the plant growth retardant. Such an effect depends on environmental characteristics and it was not observed in Londrina.

“…A espécie desperta interesses para a produção de biodiesel, pois o óleo presente em suas sementes possui todas as características necessárias para a utilização como combustível. Segundo Teixeira (2005), a produção média de frutos em cultivos comerciais chega a 5 t ha O uso de sementes com qualidade torna-se requisito principal para que a espécie possa ser utilizada no estabelecimento da cultura no campo (MARCOS FILHO, 2005;OLIVEIRA et al, 2014). Os tratamentos sanitários muitas vezes são indispensáveis, pois visam à eliminação de patógenos de campo e de armazenamento presentes nas sementes e que possam comprometer sua germinação e vigor.…”

Termoterapia e qualidade fisiológica e sanitária de sementes armazenadas de pinhão-manso

et al. 2015

ResumoDentre as várias espécies que podem ser utilizadas na obtenção de óleos vegetais para fins energéticos, o pinhão-manso tem sido considerado uma das melhores opções. Para isso, se faz necessário ter sementes de boa qualidade fisiológica e sanitária para um adequado estabelecimento das plantas no campo. O presente trabalho teve por objetivo avaliar a eficiência do tratamento térmico no controle de patógenos, de campo e de armazenamento, em sementes de pinhão-manso armazenadas. O delineamento experimental foi inteiramente casualizado em esquema fatorial 5x4 (cinco períodos de armazenamento x quatro temperaturas de tratamento). As sementes de pinhão-manso, coletadas no município de Dourados -MS, foram submetidas ao beneficiamento e secagem ao sol, em seguida foram armazenadas em câmara seca em embalagem de vidro com tampa de rosca e capacidade de 500 ml, pelos períodos de 0, 90, 180, 270 e 360 dias. Após cada período de armazenamento, as sementes foram submetidas à termoterapia por imersão em água nas temperaturas de 45°C, 50°C e 55°C por 15 minutos; a testemunha foi imersa em água em temperatura ambiente (25±2°C) por 15 minutos. Os parâmetros avaliados foram: grau de umidade, germinação, índice de velocidade de germinação, condutividade elétrica e sanidade. O tratamento térmico nas temperaturas de 45°C, 50°C e 55°C não foi prejudicial para a germinação e integridade das membranas celulares das sementes. Após 180 dias de armazenamento, a utilização da termoterapia contribui para a conservação do vigor das sementes. Os fungos Penicillium sp. e Acremonium sp. são controlados pela termoterapia nas temperaturas de 45°C, 50°C e 55°C; e Aspergillus sp. é controlado pela temperatura de 55°C nos períodos de armazenamento de 180 e 270 dias. Palavras-chave: Jatropha curcas L, germinação, tratamento térmico, sanidade AbstractAmong the many species that can be used to obtain vegetable oil for energy, Jatropha is considered one of the best options. Therefore, it is necessary to have seeds with good physiological and health quality in order to have a good establishment of plants in the field. This study aimed to evaluate the efficiency of heat treatment to the control of seed-borne pathogens in stored Jatropha seeds. The experimental design was completely randomized with a factorial 5x4 (five periods of storage x four treatment temperatures). The seeds of Jatropha were collected in Dourados -MS, and were subjected to processing and sun drying, and then stored in a dry chamber in glass flaskswith a screw cap and a capacity of 500 mL, for periods
