Investigation of quantitative and qualitative traits (Stachys inflate Benth) affected by altitude and soil in East Azerbaijan province

To determine the morphological and qualitative characteristics of five (Stachys inflate Benth) populations, a study was conducted according completely randomized design layout with three replications in 2021 season. In each growth habitat, plant samples collected from ground surface in 1×1 quadrate size. Each Stachys inflate Benth population belongs to a habitat including Yam, Bonab, Aralan, Zonozag and Galajar. Result showed that measured traits among populations had great variation. Altitude compare to soil traits had a maximum effect on percentage of essential oil, chlorophyll content and anthocyanin. Percentage of essential oil was more than 37% in Aralan population (0.186%) compare to Yam population (0.116%). The greatest accumulation of chlorophyll and anthocyanin amounts was observed in maximum altitude in Yam population. The chlorophyll content was more than 44 percent in Yam population compare to Aralan population. Generally, Aralan and Yam populations were identified as best treatments due to the highest essential oil content as well as high anthocyanin amount and using these populations can be cause to produce cultivars with desirable crop traits.
