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

A produção de biomassa e óleo essencial de híbridos de orégano cultivados sob condições climáticas da Anatólia Central

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).
