Abstract

Plant allelochemicals and their roles.

Abstract

Research is reviewed on the allelopathic effects of various plant extracts: (1) p-menthane-3,8-diols from Eucalyptus citriodora (as both natural and synthetic compounds) as inhibitors of the germination of lettuce, garden cress, green foxtail, barnyard grass and rice, and their concentrations in seedlings of various ages; (2) (+)-spathulenol as a plant growth inhibitor from E. camaldulensis; (3) bottrospicatol, a novel monoterpene produced by microbial transformation by Streptomyces spp. in the soil of (-)-carvone and carveol from Mentha spicata; (4) prenylated isoflavones as antifungal substances in Lupinus spp.; (5) an antimicrobial sesquiterpene from damaged Rosa rugosa leaves; and (6) a fungitoxin inducibly produced by dandelion (Taraxacum officinale) leaves treated with cupric chloride.
