Differential inhibition in growth of fungus Phaeolus schweinitzii inoculum was testedwith somatic embryos of two cell lines of silver fir (Abies alba Mill.) by the methodof dual cultures with pre-cultivation of somatic embryos andsubsequent removal. It was confirmedthat inhibitory substances from pre-cultivated somatic embryos L27 spreading to agar cultivation medium by simple diffusion cause greater inhibition of tester mycelial growth during subsequent co-cultivation compared to somatic embryos L122. Characteristics of embryogenic cell lines L27 and L122, from which somatic embryos were formed, are provided. Increased levels of peroxidase activity characterized the cell line L27. Natural non-induced constitutive defense of plant somatic embryos establishedby quantitatively measuredrestriction of growth in tester Phaeolus schweinitzii was discussed.

The aim of the study was to evaluate the effect of different concentrations of spermatozoa in insemination dose (ID) on fertility rate of inseminated does, and on the number of all and live-born young per litter in the breed of crossbred rabbits by using certain rates of dilution. The crossbred rabbits of female strain HYPLUS PS 19 and male strain HYPLUS PS 39 were used in the experiment. In the first part of the experiment does were inseminated with ID 0.5 cm3 with the concentrations of spermatozoa from 115 to 550 x 106 in 1 cm3. In the second part of the experiment does were inseminated with the same volume of ID (0.5 cm3), however with the lower concentration, namely from 55 to 150 x 106 in 1 cm3. The particular concentrations of spermatozoa in ID had no statistically significant effect on fertility rate and number of all and live born young per litter in both parts of experiment.
