摘      要：In the decades since the first cannabinoids were identified by scientists,research has focused almost exclusively on the function and capacity of cannabinoids asmedicines and intoxicants for humans and other *** little is knownabout the adaptive value of cannabinoid production,though several hypotheses have been proposed including protection from ultraviolet radiation,pathogens,and *** test the prediction that genotypeswith greater concentrations of cannabinoidswill have reduced herbivory,a segregating F2 population of Cannabis sativa was leveraged to conduct lab-and field-based bioassays investigating the function of cannabinoids in mediating interactions with chewing *** the field,foliar cannabinoid concentration was inversely correlated with chewing herbivore *** detached leaves,Trichoplusia ni larvae consumed less leaf area and grew less when feeding on leaves with greater concentrations of *** electron and light microscopy were used to characterize variation in glandular trichome ***-free genotypes had trichomes that appeared *** isolate cannabinoids from confounding factors,artificial insect diet was amended with cannabinoids in a range of physiologically relevant *** grew less and had lower rates of survival as cannabinoid concentration *** results support the hypothesis that cannabinoids function in defense against chewing herbivores.
