محتوای فنولی‌تام و آنتی‌اکسیدان ریشه‌ها در خاک و اجزای روزمینی درختچه‌های اقلیم نیمه‌خشک

In this study, the phenolic content and antioxidant activity of soil coarse and fine roots and aboveground components of Carpinus orientalis Miller, Crataegus microphylla C. Koch, Berberis integerrima Bunge, Prunus spinosa L and Rhamnus pallasii Fisch. and C. A. Mey shrub covers were investigated in a semi-arid region, which has not been reported in this regard so far. In the present study, first, 15 individuals were selected from each of the mentioned shrub species. Under the cover of these species, organic and mineral soil samples were taken from a depth of 0-10 cm and at a surface of 30˟30 cm and were taken to the laboratory, The biomass of the roots (coarse and fine roots) was measured in the laboratory. Also, the total phenolic content was measured by a spectrophotometer at a wavelength of 760 nm and antioxidant activity by a spectrophotometer at a wavelength of 593 nm in samples of the organic layer and roots in the laboratory. The results showed that the highest content of phenolic and antioxidant in the litterfall and fine roots parts belonged to the Crataegus microphylla C. Koch habitat, and the phenol content in the coarse root was not significant, and the lowest amount of antioxidant in the large root belonged to the Carpinus orientalis Miller habitat.
