Abstract

In the years 1978-79, a test has been carried out on european cultivars of Cannabis sativa L. In order to evaluate the content of Δ⁹-THC in function of genotype, vegetative stage and environment. The experiences have been done in different pedoclimatic environments of northern, central and insular Italy. They have shown that, in spite of the significativness of the differences found emong varieties, sexes, environments and inflorescence collection periods, the content of Δ⁹-THC 15 is so low (O,037-0,371 %) that it can't induce psicotropic effects. The investigation has moreover put in evidence the high individuai variability (the maximus variability coefficient has been 170%) which denotes the remarkable heterogeneity of the character examined.
