Photosynthesis-nitrogen relationships in tropical forest tree species as affected by soil phosphorus availability: A controlled environment study

Bloomfield, Keith; Lloyd, Jon; Farquhar, Graham


Tropical soils are often characterised by low phosphorus availability and tropical forest trees typically exhibit lower area-based rates of photosynthesis (Aa) for a given area-based leaf nitrogen concentration ([N]a) compared with plants growing in higher-latitude, N-limited ecosystems. Nevertheless, to date, very few studies have assessed the effects of P deprivation per se on Aa↔[N]a relationships in tropical trees. Our study investigated the effect of reduced soil P availability on...[Show more]
