Influence of different temperatures on the development of wheat seeds
Wheat is a crop that has extensive soil and climate adaptation. Its ideal development temperature is around 15 to 20$ºC. Therefore, it is considered a winter crop, with vegetative tolerant to frost. However, the phase of flowering and physiological maturation of the grains is extremely sensitive, so...

| description |
Wheat is a crop that has extensive soil and climate adaptation. Its ideal development temperature is around 15 to 20$ºC. Therefore, it is considered a winter crop, with vegetative tolerant to frost. However, the phase of flowering and physiological maturation of the grains is extremely sensitive, so it is possible that large productivity losses occur. This work aims to evaluate the effect of different temperatures on seed germination of wheat. This experiment was conducted in the laboratory seed Gurgacz Assis School, in the city of Cascavel - PR. Experimental design was used in a randomized block with two crops testers (BRS 208 and BRS 220), four levels of temperatures (15, 20, 25, 30 ºC) and four replications. Seeds were maintained on a photoperiod of 12 hours germination chambers with temperature control. The conclusion was that the best development of the cultures used in the experiment took place under the temperature of 15 ºC. In addition, statistical analysis allowed to observe a higher rate of germination of the crop BRS 208. |

Su temperatura ideal para desenvolvimiento es alrededor de 15 y 20 ºC. Por ello, es considerado un cultivo de invierno, con fase vegetativa tolerante a la helada. Sin embargo, la fase de floración y maturación fisiológica de los granos es extremamente sensible, de modo que es posible que grandes pérdidas de productividad ocurran. El trabajo tiene por objetivo evaluar el efecto de diferentes temperaturas en la germinación de semillas de trigo. Este experimento ha sido realizado en el laboratorio de semillas de la Facultad Assis Gurgacz, en la ciudad de Cascavel - PR. Se utilizó delineamiento experimental en bloques al azar con testers de dos cultivos (BRS 208 y BRS 220), en cuatro niveles de temperaturas (15, 20, 25,30 ºC) y con cuatro repeticiones. Las semillas fueran mantenidas en un fotoperíodo de 12 horas en cámaras de germinación con control de temperatura. La conclusión fue que el mejor desenvolvimiento de los cultivos utilizados en el experimento ocurrió bajo la temperatura de 15 ºC. Además, el análisis estadístico posibilitó observar un mayor índice de germinación del cultivo BRS 208. O trigo é uma cultura que apresenta ampla adaptação edafoclimática, possuindo como temperatura ideal para seu desenvolvimento, próximas de 15 a 20 ºC. Por isso, é considerado uma cultura de inverno, sendo a fase vegetativa tolerante a geada. No entanto, a fase de floração e maturação fisiológica dos grãos é extremamente sensível, podendo ocorrer grandes perdas de produtividade. O trabalho tem por objetivo avaliar o efeito de diferentes temperaturas na germinação de sementes do trigo. O presente experimento foi realizado no laboratório de sementes da Faculdade Assis Gurgacz, na cidade de Cascavel - PR. Utilizou-se delineamento em blocos casualizados, sendo testadas duas cultivares (BRS 208 e BRS 220) e quatro níveis de temperaturas (15, 20, 25, 30ºC), com quatro repetições. As sementes foram mantidas no fotoperíodo de 12 horas em câmaras de germinação com controle de temperatura. Concluiu-se que o melhor desenvolvimento das cultivares utilizadas no experimento aconteceu na temperatura de 15 ºC e, também, pode-se observar maior índice de germinação acultivar BRS208 mediante a análise estatística.
