Tóm tắt

Strawberry fruit samples collected in Japan and Dalat (Lam Dong) were analyzed for stable isotope composition δ15N using the Isotope Ratio Mass Spectrometry system (EA-IRMS). The results of the ANOVA test showed a statistically significant difference at =0.05 among the stable isotope composition δ15N in the organic strawberries from Japan compared to conventionally grown and greenhouse grown strawberries in Dalat and Japan with ????−????????????????????????<0.001. Specifically, the mean δ15N value in organic strawberries grown in Japan (4.720‰) was more enriched than that obtained from samples conventionally grown (0.020‰ and 0.864‰) and greenhouse grown (0.103‰) in Dalat and Japan. Additionally, the average δ15N value in hydroponically grown strawberries in Dalat (5.283‰) did not differ significantly from the organic strawberries in Japan at the α=0.05 level of significance.
