Abstract
Strawberry samples were collected from Dalat and Mocchau regions and extracted by a cryogenic vacuum method. Stable isotope compositions δ2H và δ18O in the extracted water were then analysed by a Liquid Water Isotope Analyzer (LWIA-24D). The evaluated results showed that, at the statistical significance level α=0.05, the δ2H and δ18O values obtained at Mocchau and Dalat samples are clearly different (p<0.001). In detail, the mean value of δ2H for strawberries grown in Mocchau (-42.83‰) was more enriched than that in Dalat (-53.99‰). In contrast, the value of δ18O for strawberries grown in Mocchau (-9.25‰) is more depleted than in Dalat (-5.67‰). In addition, the δ2H and δ18O values in each region are strongly correlated and can be distinguished based on the position of the correlation line relative to the global meteoric water line.
