The stress metabolites rishitin and lubimin accumulate at relatively low concentrations (5–20 ppm) in potato tuber slices subjected to various cell disruptive treatments including heavy metal salt, sulfhydryl reagents, metabolic inhibitors, detergents, ultrviolet light and lysosomal enzymes. Cold stored (4°C) tubers are more disposed to terpene accumulation than freshly harvested, 25°C stored and conditioned potatoes. Various inhibitors of DNA transcription and mRNA translation block terpene induction by non-specific elicitors when applied at sufficiently high concentration. However, various protein synthesis, inhibitors are potent elicitors of terpene-accumulation when applied at lower concentration. Actinomycin D (25
