Abstract
Realizou-se o presente trabalho com o objetivo de estudar a germinação de sementes de cultivares de Panicum maximum Jacq. (Colonião, Tobiatã, Centenário, Centauro e Tanzânia), em testes sobre substratos umedecidos com três quantidades de solução de nitrato de potássio a 0,2%, quais sejam: 12, 16 e 20 ml. Depois de semeados, os gerboxes foram fechados com fita crepe e levados para germinador. As contagens de germinação foram realizadas de 7 em 7 dias, sem se acrescentar água, e os gerboxes mantidos vedados. Os resultados permitiram concluir que houve diferença entre os testes, dependendo da quantidade de solução utilizada, tendo a germinação com 12ml superado a das demais.
This work was carried out to study the germination of Panicum maximum Jacq. seeds, Colonião, Tobiatã, Centenário, Centauro and Tanzânia varieties, on substrata moistened with three different volumes of 0.2% potassium nitrate solution: 12, 16 and 20ml. After sowing, the gerbox covers were tied with tape and no water was added. Germination counts were done each 7 days. The germination test results pointed out that there were differences among them, depending on the amount of solution applied. The germination percentage with 12 ml of solution applied to the substrata was greater than for the others.
