Abstract
Effect of reduced light intensity (minus 26%) on trichomes characteristics and herb yield responses of three subspecies of Origanum vulgare (ssp. vulgare, ssp. hirtum (Link) letswaart and ssp. viride (Boiss.) Hayek) and a hybrid (ssp. viride (Boiss.) Hayek x O. majorana L.) was investigated. It was found that the investigated genotypes showed different morphological characteristics which were significantly influenced by light reduction. The applied treatment decreased the total indumentum of the leaves as well as the density and size of capitate glandular trichomes and size of peltate glandular trichomes. The theoretical volume of essential oil on one peltate glandular trichome as well as the total theoretical volume of essential oil on the adaxial side of the leaves was reduced under this condition. The indumentum of all samples included non-glandular trichomes, peltate glandular trichomes and capitate glandular trichomes type I. Capitate glandular trichomes type II with low density were observed only on O. vulgare ssp. viride and on the hybrid. Based on the findings of this study, it can be suggested that the applied light reduction was a limiting factor for the growth of O. vulgare L. plants. It shifted the carbon allocation to increase plant surfaces. As a result, the density of trichomes, which is proposed to be a fixed factor in O. vulgare L. plants, decreased.
