The biomass and essential oil production of oregano hybrids cultivated under Central Anatolian climatic conditions

Abstract

Flora of Türkiye is hosting many Origanum sp. and spp. valuable members of Lamiaceae, including outstanding endemic species and hybrids. Those are having a number of using field and still meeting the World’s major demand. Five combinations of artificial Oregano hybrids were cultivated in Ankara ecological conditions. Among those species; Origanum minutiflorum and Origanum onites are endemic to the flora of Türkiye and the combinations of those hybrids are very valuable and unique. According to the field studies results; the highest green herb yield was provided from H4 as 439.93g and from H5 as 317.26 g x plant-1. H2 and H3 showed the highest green leaf yield by 278.69 and 244.33 g x plant-1, and the highest leaf ratio (%). The essential oils ranged between 4.20% and 5.96%, Carvacrol predominated in the hybrids at; 77.90% (H1), 61.26% (H3) and 26.99% (H4), 72.09 (H5), and linalool at 45.86% (H2).
