Effects of different temperatures and duration on germination of Lentil (Lens culinaris Medik.) seeds

The aim of this study was to seek optimum seed germination temperature of Lentil seeds. Germination tests were conducted for twenty-four genotypes with 3 replicates in a completely randomized design, were conducted to investigate germination behavior of lentil seeds subjected to six different heat temperatures (39, 46, 54, 61, 68 and 75°F) and duration on germination. The experiment results revealed that different temperature treatments were effective on mean germination percentage and suggested that there is relationship between the temperature treatment and germination rate. The mean germination was obtained for 39, 46, 54, 61, 68 and 75°F, 0.945, 1.590, 1.864, 2.305, 2.840 and 2.573 respectively. The experiment revealed that the different temperature treatments were effective on mean germination percentage and seeds germinated faster at higher constant temperatures and optimum germination occurred at 68°F.
