Is ¹⁴C concentration higher for plants growing at high altitudes than that for those at the sea level?

Abstract

To answer a question whether 14C concentration is higher for plants growing at high altitude areas than those growing at the sea level, we recently have collected plant samples from four sites at different altitudes: (1) plants from Lake Pumayum area at the altitude of 5,030m; (2) plant samples from the suburbs of Lhasa city at the altitude of 4,000m; (3) needle leaves from pine tree at 2,600m-high location of Mt. Fuji; and (4) needle leaves from pine trees growing in the Higashiyama Campus of Nagoya University at the altitude of 50m. 14C concentrations of the terrestrial plants will be discussed in accordance with their growing altitudes.
