Mycorrhization causes increase in essential oil yield regardless of the hydric state of the plant.
Water stress also shows a slight increase in essential oil contents.
Similarly, a significant increase in essential amino-acids (methionine 47.68%, lysine 59.41% and, tryptophan 38.05%) was recorded.
Our results also show that water stress causes a slight increase in essential oil yield; this increase may be a result of the activation of certain enzymes involved in the synthesis of some secondary metabolites implicated in defense.
In the same way, Khaosaad et al. [15] showed in two species of basil (O. vulgare and O. basilicum) that the inoculation with G. rosea and G. mosseae lead to an increase in essential oil yield and changed the composition.
These results are in agreement with those of Khalid [14] who reported an increase in essential oil yield after applying water stress on Ocimum basilicum L., Ocimum americanum L., Cymbopogon nardus L., and Cymbopogon pendulm L. plants.
With progressing seed development, seeds per plant, seed weight and seed yield enhanced, leading to an increase in essential oil yield, despite decreasing essential oil percentage and per seed.
Water deficiency after beginning of blooming (folded flowers) can induce an increase in essential oil content and thus result in higher quality of oregano herbage and higher water use efficiency of oregano plants.
