Abstract
  • The results of a single publication stating that terrestrial plants emit methane has sparked a discussion in several scientific journals, but an independent test has not yet been performed. * Here it is shown, with the use of the stable isotope (13)C and a laser-based measuring technique, that there is no evidence for substantial aerobic methane emission by terrestrial plants, maximally 0.3% (0.4 ng g(-1) h(-1)) of the previously published values. * Data presented here indicate that the contribution of terrestrial plants to global methane emission is very small at best. * Therefore, a revision of carbon sequestration accounting practices based on the earlier reported contribution of methane from terrestrial vegetation is redundant.
摘要
  • 一篇单一出版物称陆生植物会排放甲烷的结果在几本科学期刊上引发了讨论,但尚未进行独立测试。* 在此,通过使用稳定同位素(13)C和基于激光的测量技术表明,没有证据表明陆生植物有大量需氧甲烷排放,最多为先前公布值的0.3%(0.4 ng g(-1) h(-1))。* 此处呈现的数据表明,陆生植物对全球甲烷排放的贡献充其量非常小。* 因此,基于先前报道的陆地植被甲烷贡献对碳封存核算方法进行修订是多余的。
