CULTIVATION OF SOME MEDICINAL AND AROMATIC PLANTS UNDER DIFFERENT LIGHT INTENSITY AND DETERMINATION OF SECONDARY METABOLITES AND PHYSIOLOGICAL IMPACTS
Project no. 1041 · Status: Kapanmış · 2017
Summary
Cultivating medicinal and aromatic plants including sage tea, rosemary and thyme under new or prior set up garden could be additional income for farmers. However, the income depends on yield and quality of these plants which are affected from shade of trees. In this project, some yield and quality characteristics of sage tea, rosemary and thyme were assessed under different shading conditions. There were three different shading effect as 0%, 40% and 75%. Green herba, drog herba, plant height, leaf area, chlorophyll-a, chlorophyll-b, and carotenoid contents, essential oil rate and components were measured, and these features were comparatively associated together. According to results, drog herba yield were decreased in each three species, however this decrease was regressed in second year. First year of shading conditions, the plants grew through intra row in order to get more sunlight. Yet, this effort of reach to sunlight were evolved to increasing plant height in second year. Generally, leaf area and pigment contents were increased by shading conditions. Each three species showed different elevations in terms of essential oil rate. Besides, essential oil components of sage tea and thyme were showed significant alteration under shading conditions. It was concluded that each three species need to some agronomic arrangements and developments which enable to improve yield and preserve essential oil rate under shading conditions.
