Sainfoin (Onobrychis viciifolia) is a perennial leguminous forage crop used for hay production or grazing in the temperate regions of the world. The objectives of this study were to evaluate the effects of seed size and pod removal on sainfoin seed germination under different
temperatures. Seed size (P < 0.001) and seed pod removal (P < 0.001) had significant effects on sainfoin seed germination. Final seed germination was 2.4, 91.6 and 81.0%, respectively, for three accessions, 'PI636518' (small seed size class), 'Shoshone' (medium seed size
class) and 'Svkpiestt' (large seed size class). However, final seed germination was not different (P = 0.292) for large and small seed size classes selected from the same accession. Final germination percentage was not significantly different among the three alternating temperature
regimes of 25/15°C, 20/10°C and 15/5°C. Final germination was increased by seed pod removal.
