Abstract
Investigation of temperature (10 and 20ºC) and pH values of water solution
(pH 4, 5, 6 and 7) influence on seed germination and seedling traits (radicle, hypocotyls
and seedling length) of two red clover cultivars (Danish Rajah and Polish Viola) seeds
was carried out in growth chamber. Seed was germinated by the rolled filter paper
method during 10 days. Significant influence (p=0.01) of temperature and pH values on
all investigated traits was found. Differences between cultivars were also significant
(p=0.01) for all traits with exception of radicle length. Higher average values of
investigated traits were obtained at higher temperature. Regarding pH values, the
highest average germination was found at pH 4 and 6, and the lowest at pH 5. The
average radicle length was highest at 4 and the lowest at pH 7. Values of average
hypocotyls and seedling length were highest at pH 4 and the lowest at pH 5. Cultivar
Rajah obtained higher average germination, hypocotyls and total seedling length.
