We used jasmonate solutions with 0, 1, 5, 10 and 100 µM concentration for treating of plants. Plant treated with Jasmonate showed an increase in chlorophyll a content in comparison with control plants. However chlorophyll b content only increased in 5 µM jasmonate treatment. Also carotenoid content increased in all treated plants but there was no significant difference between various concentrations of jasmonate. The amount of α-tocopherol enhanced in plants treated with 10 and 100 µM jasmonate. Treatment with 1 and 5 µM jasmonate caused a considerable increase in tetrahydrocannabinol. 5 µM jasmonate solutions were more effective in this regards. Cannabidiol content decreased in all plants treated with jasmonate. These results showed that jasmonate encourage the accumulation of primary and secondary isoprenoids in chloroplasts.
