“…These results show the importance of adjusting the time of sowing, which, in this study, favored the initial seedlings stand, and later increased the grain yield, as also noted by Mielezrski & Marcos Filho (2012) for pea. However, despite the lower physiological quality, Tec Frontale presented the highest average yield, contrary to the results found by Abati et al (2017), where the high vigor of wheat seeds treated with imidacloprid and carboxy + thiram benefited the seedlings stand and grain yield. For Schuch et al (2000), differences in vigor of black oat seeds affected only the initial plant growth, and the effects of seed vigor were reduced as the crop developed.…”

New technologies are being incorporated to the seed treatment process, such as the use of products on industrial scale. This study aimed at evaluating the seed quality of wheat cultivars, as well as the influence of the seed treatment method on the establishment and yield of this crop. Seeds of the cultivars Jadeite 11, Quartzo and Tec Frontale were treated with the Spectro® fungicide (difenoconazole - 200 mL 100 kg-1 of seeds), Cruiser Opti® insecticide (thiamethoxam + lambda-cyhalothrin - 200 mL 100 kg-1 of seeds) and Polifix G4 polymer (100 mL 100 kg-1 of seeds). A completely randomized design, with four replicates, was used. The treatments consisted of industrial treatment, on farm treatment with the same products and control. Germination, first germination count and moisture content tests were carried out immediately after the seed treatment and at 30, 90 and 150 days of storage. Seedling emergence in beds was evaluated at 30, 60 and 120 days of storage. Under a randomized block design, seedling emergence and grain yield were evaluated in the field in two sowing seasons. The conventional or industrial seed treatment methods do not reduce the physiological quality and emergence of high-vigor seeds stored for 150 days, under controlled conditions of temperature and humidity. The conventional or industrial seed treatment with diphenoconazole + thiamethoxam + lambda-cyhalothrin + polymer does not increase the wheat crop plant stand and grain yield.

“…The character number of tillers per plant is influenced by many factors, including genetics, which can explain the high coefficient of variation value (Pimentel Gomes, 2009). In a study developed by Abati et al (2017), in which they have evaluated number of tillers per plant, a similar coefficient of variation was reported (29.3%).…”

The aimed to evaluate the effect of different nitrogen doses in association with sulfur fertilization on yield components and seeds physic-quality attributes. The experimental design was randomized blocks, arranged in a 3 × 5 × 2 factorial design (cultivar × nitrogen doses × sulfur management), with four replications. The analysis of variance revealed that wheat cultivars × sulfur management interaction was significant for height insert of main spike. Interaction was verified between cultivars × nitrogen doses for number of tillers per plant and number of spikes per m2. The nitrogen doses × sulfur management interaction was significant for number of tillers per plant. Interaction between cultivars × nitrogen doses were observed for number of spicules per spikes and number of seeds per spike. Nitrogen fertilization has different effects on wheat cultivars. The cultivar ‘TBIO Sinuelo’ presents greater seeds yield with improvement of nitrogen fertilization doses. High nitrogen doses provide increasing of wheat seeds yield. Nitrogen doses influence differently on yield components of wheat. Number of tillers per plant is correlated with seeds yield. Physical attributes of wheat seeds are not influenced by nitrogen doses increasing. Sulfur fertilization promotes tillering and increment of number of spicules per spike. The cultivar ‘TBIO Sinuelo’ presents higher weight per 1000 seeds, followed by ‘Jadeíte 11’, and ‘TBIO Sintonia’.

“…More vigorous seeds lead to faster initial growth of seedlings, with greater capture of light and better use of resources from the environment (Amaro et al, 2014). However, at greater densities, plants coming from vigorous seeds compete more for environmental resources, due to their greater capacity for establishment in the field (Abati et al,2017), which contributes to obtaining a large number of plants per area. Thus, they may produce seeds with smaller amounts of seed reserves due to the greater intraspecific competition established.…”

“…Seeds of different vigor levels and different cultivars at the same sowing density show different results regarding tillering capacity, germination, and seedling emergence (Abati et al, 2017); they establish different conditions for development of the crop and of the seeds produced. Thus, the interaction between initial vigor and the sowing density used can lead to different results regarding seed yield and physiological potential.…”

Initial seed vigor and sowing density interact in establishment of plants in the field, and can thus affect expression of the plasticity of the wheat crop and the yield and physiological quality of the seeds produced. The aim of this study was to evaluate the effect of seed vigor levels in combination with sowing densities on the yield and physiological potential of wheat seeds. The cultivars BRS Gralha-Azul and BRS Sabiá were used in a randomized block experimental design in a 2 × 4 factorial arrangement, with four replications. The treatments consisted of seeds of high and low vigor and four sowing densities (150, 250, 350, and 450 seeds.m-2). The following evaluations were made: seed yield, germination, first germination count, seedling length, seedling dry matter, accelerated aging, emergence speed index, and seedling emergence in sand. An increase in sowing density favors the seed yield of both cultivars; however, it reduces the vigor of the seeds produced by the cultivar BRS Gralha-Azul, especially of the seeds produced by plants originating from high vigor seeds. For the cultivar BRS Sabiá, an increase in sowing density decreases the germination performance of seeds produced by plants originating from low vigor seeds.
