The aim of this investigation was to estimate the effect of four pH levels of germination media (4, 5, 6 and 7) on seed germination energy (GE), germination (G), percentage of dead or infected seeds (DIS), percentage of hard seed (HS), normal (NS) and abnormal seedlings (AS), root length (RL), shoot length (ShL), seedling length (SeL), fresh weight (FW) and dry weight (DW) of seedling, and seedling vigor index (SVI) in two red clover genotypes (cv. K-17 and cv. Kolubara). The experiment was conducted in the laboratory conditions of the Institute for Animal Husbandry in Belgrade (Serbia) during January 2011. The pH levels of germination media had significant effect on the NS (P is less than 0.01), AS (P is less than 0.01), RL (P is less than 0.05), ShL (P is less than 0.01), SeL (P is less than 0.01), FW (P is less than 0.01) and SVI (P is less than 0.05). The lowest GE, G, NS, ShL, SeL, FW and SVI were found at pH 4. Also, the highest DIS, HS and AS were found at pH 4. The genotype had significant effect on HS (P is less than 0.01), RL (P is less than 0.01), ShL (P is less than 0.01), SeL (P is less than 0.01), FW (P is less than 0.01) and SVI (P is less than 0.01). Genotype and pH levels of germination media did not affect on GE, G, DIS and DW significantly.
