Altitude Triggers Some Biochemical Adaptations of Polygonum cognatum Meissn. Plants

Abstract

Madimak is a local name of Polygonum cognatum which is known as a nutrient- and phenolic-rich edible plant in Turkish traditional cuisine. Knotweed (madimak) is usually found in both agricultural and non-agricultural areas at different altitudes from 720 to 3000 meters. This study aimed to investigate some biochemical effects of altitude in knotweed plants. Knotweed leaf samples collected from two different elevations (1656 and 1170 meters) of mountainous regions of Şebinkarahisar (Giresun, Turkey) at optimum vegetation stage. The total chlorophyll and carotenoid levels were determined in fresh leaves while the total flavonoid amount, proline and the total soluble sugar contents in dried leaf samples spectrophotometrically. The proline and the total flavonoid contents were more abundant whereas the amounts of soluble sugars, the total chlorophyll and carotenoids decreased at higher altitude plants. Altitudinal gradient affects the important parameters in the biochemistry of knotweed.  Especially, owing to the flavonoid-rich content, higher located knotweed could be defined as a functional food.
