“…According to the stadium basal temperatures are different, for example, there were determined for canola -0,8 ° C for vegetative stage stadium and 10,0 ° C for flowering [8]. Therefore all seeding times were harmed.…”

“…The mentioned characteristics may vary according to genetics and the environment agricultural management and environmental, such as water availability and frost, are control variables in the qualitative and quantitative yield of canola [7,8]. At the seeding time, we used 18 seeds per meter and spacing between rows of 0.45 m. There was applied, in the furrow, 100 kg ha -1 of fertilizer (NPK formula 13-33-00).…”

“…The ideal temperature ranges from 12 to 30 °C and the growth optimum temperature is 25 °C, with thermal stress above it (EDWARDS;HERTEL, 2011;MENDONÇA et al, 2016). Luz et al (2012) observed that for Hyola 61 and Hyola 433 in Santa Maria -RS, the vegetative period last from 52 to 78 days and from 49 to 76 days, respectively, according to the sowing date.…”

“…In Santa Maria -RS, Hyola 61 and Hyola 433 early to late flowering duration ranged from 34 to 81 days, according to sowing date (LUZ et al, 2012). Nied (2013) observed that in the reproductive period the average thermal sum was 823 and 846 degree-day at 79 and 63 days, in 2010 and 2011, respectively, considering the average thermal sum for each year, for both Hyola 432 and Hyola 61 hibrids.…”

Canola agronomic performance in three sowing dates in Jataí-GO

et al. 2020

Canola (Brassica napus L. var oleifera) is a potential crop due to the growing world demand for vegetable oil. This work aims to evaluate the performance of five canola hybrids in three sowing dates in Jataí-GO. The experiment was conducted in the year of 2017, in a randomized block design, with subdivided plots and four replications. Plots were composed by three sowing dates (03/03, 03/10 and 03/17) and subplots by the canola hybrids Hyola 50, Hyola 61, Hyola 433, Hyola 571CL and Hyola 575CL. Seedling emergence, inicial and final plant population, flowering, maturation, plant height, plant survival index and grain yield were evaluated. The thermal sum calculation was performed with the phenological data. Results were submitted to analysis of variance and means were compared by Scott Knott test at 5% of probability. The plants survival index highlighted Hyola 433, Hyola 571CL and Hyola 575CL hybrids. Grain yield varied according to hybrid and sowing date. In the edaphoclimatic conditions of this study, in the year of 2017, the best agronomic performance was observed in the first sowing date for the canola hybrids Hyola 433 and Hyola 575CL and in the second sowing date for the canola hybrid Hyola 571CL.

“…In Brazil, canola cultivation started in the 1980s and currently involves only spring canola of the species B. napus var. oleifera, used in crop rotation systems mainly in the south of the country (Luz et al, 2012). The state of Rio Grande do Sul has been considered an outstanding state in terms of the production and planted area of canola, with values of 85.2% and 86.7%, respectively.…”

<b>Influence of pollination on canola seed production in the Cerrado of Uberlândia, Minas Gerais State, Brazil

et al. 2018

The objective of this study was to evaluate the influence of pollinating insects on canola productivity for different commercial hybrids, Hyola 61 and Hyola 433, in Minas Gerais State, Brazil. The studies were conducted at the Fazenda Experimental Água Limpa of the Federal University of Uberlândia. To evaluate the influence of pollination by bees on the production of canola seeds, an experiment was carried out to exclude floral visitors and compare canola seed production following four treatments: (a) autogamy in Hyola 61, (b) autogamy in Hyola 433, (c) open pollination in Hyola 61, with insects having free access, and (d) open pollination in Hyola 433, with insects having free access. Flowers that were available for pollination had 25% and 18.8% heavier pods and 22.5% and 20.6% more seeds per pod in Hyola 61 and Hyola 433, respectively, than those bagged without pollination. The results show that the cross-pollination process, fostered by pollinator visits, positively influenced some parameters related to production, presenting an advantage in relation to canola autogamy in Cerrado Mineiro.Serviços de polinização na produção de sementes de canola no Cerrado de Uberlândia, Estado de Minas Gerais, Brasil RESUMO. O objetivo desse estudo foi avaliar a influência da polinização por abelhas na produtividade de canola em diferentes híbridos comerciais, Hyola 61 e Hyola 433, em Minas Gerais. Os estudos foram conduzidos na Fazenda Experimental Água Limpa da Universidade Federal de Uberlândia. Para avaliar os efeitos da polinização de abelhas na produtividade nas sementes de canola, realizou-se um experimento com exclusão dos visitantes florais, comparando a produção em quatro tratamentos: (a) autogamia em Hyola 61 e (b) autogamia em Hyola 433; (c) polinização aberta em Hyola 61 e (d) polinização aberta em Hyola 433 com acesso livre de insetos. As flores disponíveis para polinização apresentaram 25% e 18,8% sílicas mais pesadas e 22,5% e 20,6% mais sementes por sílica em Hyola 61 e Hyola 433, respectivamente, do que aquelas privadas de polinização. Os resultados apontaram que o processo de polinização cruzada, favorecida pela visita de insetos polinizadores, influenciou positivamente alguns parâmetros relacionados a produção, demonstrando-se vantajosa em relação à autogamia da canola no Cerrado Mineiro.Palavras-chave: Apis mellifera; Brassica napus; tropicalização; produtividade.
