Ecophysiological responses of white birch seedlings to soil temperature and phosphorus supply under current and doubled carbon dioxide concentration

Abstract

To investigate the responses of some physiological and morphological traits to different soil temperature and phosphorus supply under current and doubled carbon dioxide concentration ([CO2]), white birch (Betula papyrifera Mash) seedlings were exposed to three soil temperatures (Tsoil) (7, 17 and 27C) and three levels of phosphorus (P) (241, 493 and 951 mg/L) under current and doubled carbon dioxide concentration.
