Temperature and Precipitation Effect on the Production of Flavonoids in Wild Populations of Stevia Salicifolia in Queretaro.

EasyChair Preprint 3751

Abstract

Plants respond physiologically to the meteorological variations of the area where they grow and develop. The temperature and precipitation are two of the main meteorological conditions that affect the metabolism in plants, mainly the secondary metabolism, in which substances such as flavonoids are produced that allow the cell to be protected from an oxidative stress caused by both biotic and abiotic factors. The objective of this work was to analyze the meteorological condition that affects the physiology in Stevia salicifolia in wild populations for the synthesis of total flavonoids. Four populations were established, two in the municipality of Amealco, one in the municipality of Huimilpan and the last in the municipality of Cadereyta. The highest concentration of total flavonoids was obtained from the Huimilpan population, followed by the Amealco populations and the lowest concentration was obtained from the Cadereyta population. Based on the statistical analysis of multivariate correlations, it was established that temperature is the main factor of flavonoid synthesis in S. salicifolia, since the highest concentration of total flavonoids was obtained in a temperature range of 27.20-28.60 °C, while that the least concentration was obtained in a range of 19.20 - 21.1 °C.
