Intact current-year needles from 3-year-old lateral branches of healthy seedlings obtained from the understory of a subalpine coniferous forest on the eastern edge of the Tibetan Plateau in China, growing within 10-liter plastic pots filled with sieved surface sandy soil (collected from the forest) and placed within closed-top chambers located at either a relatively high elevation (HE = 3200 m) with no added nitrogen (0 N) to the soil in which they were growing
