Abstract
The total monoterpenoid content of the pine litter layer and the availability of these compoundsas inhibitors/stimulators onPolysphondylium violaceum of cellular slime molds were investigated. In order tosenescent, and decaying needles from 3 pine species ( Pinus densiflora, P. thunbergi, P. rigida) by litter bagmethod. Total monoterpenoid content was highest in the fresh needles, but also remained relatively high insenescent needles. The effect of monoterpenoids identified fromPinus plants on the growth ofP. violaceum wasstudied. We tested four concentrations (1, 0.1, 0.01, and 0.001μg/μL) of each compound by using a diskvolatilization technique. Each compound was treated after germination of spores ofP. violaceumcompounds at 1 μg/μL concentration had a very strong inhibitory effect on cell growth ofP. violaceum.Fenchone at all concentrations, myrcene, verbenone, bornyl acetate, and limonene at low concentrationsstimulated the growth ofP. violaceum. These results suggest that inhibitory or enhancing effects of selectedmonoterpenoids depend upon the concentration of the individual compound.
