Growth response of Mountain birch to air and soil temperature: is increasing leaf‐nitrogen content an acclimation to lower air temperature?
Summary Growth and nitrogen (N) economy of mountain birch are reported here in response to temperature change. Mechanisms of temperature effects on plant growth in temperate–arctic regions are discussed in the light of decreasing growth rates and increasing leaf‐N contents along altitudinal and lati...
