| The total monoterpenoid content of the pine litter layer and the availability of these compounds as inhibitors/stimulators on Polysphondylium violaceum of cellular slime molds were investigated. In order to determine the several monoterpenoids in the natural environment, we examined their concentrations in fresh, senescent, and decaying needles from 3 pine species (Pinus densiflora, P. thunbergii, P. rigida) by litter bag method. Total monoterpenoid content was highest in the fresh needles, but also remained relatively high in senescent needles. The effect of monoterpenoids identified from Pinus plants on the growth of P. violaceum was studied. We tested four concentrations (1, 0.1, 0.01, and $0.001;{mu}g/{mu}L$) of each compound by using a disk volatilization technique. Each compound was treated after germination of spores of P. violaceum. All of the compounds at $1;{mu}g/{mu}L$ concentration had a very strong inhibitory effect on cell growth of P. violaceum. Fenchone at all concentrations, myrcene, verbenone, bornyl acetate, and limonene at low concentrations stimulated the growth of P. violaceum. These results suggest that inhibitory or enhancing effects of selected monoterpenoids depend upon the concentration of the individual compound. |
