Abstract : Temperature is the main factor affecting plant growth and development. Seed germination and seedling establishment are the most critical stages in the life cycle of plants For the purposes of the study, the germination temperatures of six cool-season legumes (Vicia faba, Lens esculentus, Vicia sativa, Lupinus albus, Pisum sativum, and Lathyrus sativus) important cultivars were determined. Seed germination rate was measured at different temperatures in the range 4-10 in a growth chamber with constant parameters (light, water) at three-day intervals for a period of three weeks. Each treatment was repeated four times for each temperature value, where 100 seeds were placed in five different separate glass made containers. The measurements were taken at three-day intervals. A seed was deemed to have germinated when at least 1 mm of radicle was visible.It was found that pea germinated faster than the rest cultivars under low temperatures, whereas Vicia sativa and Lathyrus sativus showed the slowest germination rates. The descending order of germination rate Pisum sativum> Vicia faba > Lens esculentus> Lathyrus sativus >Vicia sativa>Lupinus albus. Germination rate increased with increasing temperature for all cultivars. Lupinus albus was the legume seed with the less germination percentage. Therefore, temperature is the most limited factor on germination process and the increase of 4 degrees is enough to give better germination results. As a general conclusion, Pisum sativum and Vicia faba may satisfactorily germinate in rather cool micro-environments, and their sowing in the fall may be postponed for some weeks without substantial germination risk comparing to the rest legume cultivars.
