Resumo
Seeds presents variable germination performance at different temperatures and substrates, which are basic components of germination test. Within this context, this work aimed to adapt the methodology for the seeds germination’s test of P. sativum subsp. arvense. The experiment required four portions of seeds, five temperature degrees (15, 20, 25, 20-30 and 15-25 °C), and two substrata (roll of paper and in sand). Seeds evaluation considered the following: moisture degree and germination test. The effect of seed portion, substrata and temperature in germination was assessed on a daily basis. It was calculated the rate of germination, of anormal plants, of dormant and dead seeds, and of speed of germination index; initial, final and average times, and synchrony. The experimental design consisted of random blocks with four replications, while conjoint analysis was the statistical procedure adopted. The germination test for forage pea seeds should be conducted at the constant temperature 20 °C in roll of paper substrate with the first count and final count on the 4th and 7th day, respectively.
