Abstract
Influence of different pH values of water solution on germination energy, germination, seedlings root length and stem height of two annual forage legumes was tested in laboratory conditions in order to evaluate tolerance of species and cultivars to stress conditions caused by lower or higher pH in the earliest phases of growth. Two soybean cultivars (Anica and Ika) and two forage pea cultivars (Zekon and Timo), which differentiated in seed size were tested at four pH levels of water solution (5, 6, 7and 8). Seed of all investigated cultivars was produced in 2003. Germination energy and germination were not significantly affected by the pH of water solution. Root length and stem height of seedlings of both species were significantly affected (p=0.01) by the pH of water solution. The highest values for root length were found at pH=6 (8.01 cm). Stem was highest in both species at pH=6 and 7 (7.53 and 7.07 cm).The lowest average root length value (5.72) was found at pH=7. The lowest average stem height (6.02 and 6.07 cm) was at pH=5 and 8. Differences among all investigated traits of cultivars for pH values in average were significant (p=0.01). Soybean cultivar Ika had the highest germination energy (70.1%), and soybean cultivar Anica had the highest germination (80.8%). Forage pea cultivar Timo had the highest average value of root length and stem height (8.17 and 10.18 cm, respectively).
