Sažetak (engleski)

This paper presents the results of germination and development of spruce seeds
in different ph solutions under laboratory conditions. ten different ph concentrations
were used with 4 repetitions each. concentration values ranged from
ph 1.7 to 6.7. sulphuric acid (h2so4) and deionized water were used to prepare
the solutions. seed germination and development were tested according to the
Ista rules. germination was tested in an illuminated incubator (snijders model
ecd01e, tilburg, netherlands).
the results provided some fundamental information on seed germination in different
ph solutions for spruce and fir species. in addition, very useful information
was obtained that will facilitate understanding of natural regeneration,
particularly in changing environmental conditions (acid rain, soil acidity, etc.).
the threshold ph value for normal seed germination was 2.6. soil ph values in
croatia range between 2.7 and 8.10, with only 0.38% of soils having ph values
lower than 3. generally, natural ph concentrations of soils are favourable for
spruce seed germination.
