Abstract:: δ¹⁵N can be used to trace the nitrogen cycle in ecosystems,and thus are potential tools to investigate the nitrogen cycles in context of plant physiology and ecology.Recent studies have shown that the variation of pretreatment method may affect sample δ¹⁵N.In this study,we investigated the effects of different pretreatment method on sample δ¹⁵N and nitrogen content.The results show that no difference was found for sample δ¹⁵N and nitrogen content by pretreatment of high temperature desiccation under 105℃ and then drying under 40℃ or drying under 40℃ only.The results imply that no effect was found for sample pretreatment on sample δ¹⁵N and nitrogen content.
