Abstract
Crimson clover (Trifolium incarnatum L. convar. Inkara) seeds were imbibed with water solution of various pH values
(4, 5, 6 and 7) at various ambiental temperatures (10, 15 and 22 °C) with the aim to reveal treatments effects on seed
(imbibition, germination energy, germination and electric conductivity) and seedling traits (stem, root and total length).
Seeds were imbibed in a laboratory by the standard method for seed germination. When averaged over the inquired pH
values, ambient temperature affected all the investigated traits except stem length. The highest seed imbibition (58.8%)
and electric conductivity (82 µS/cm per gram) were achieved at 22 °C. The highest values for germination energy (70%),
germination (68%), root length (31 mm) and total seedling length (77 mm) were achieved at 10 °C. When averaged over
the inquired ambiental temperatures, the highest germination energy (71%), germination (73%), root length (34 mm) and
total seedling length (78 mm) were achieved at pH 4.
