Response of ecological stoichiometry of carbon, nitrogen and phosphorus in plants to abiotic environmental factors

Plants exert different physiological and biochemical reactions in different environments, through adjusting metabolisms and circulations of carbon, nitrogen and phosphorus. Then, plants show different contents and distributions of carbon, nitrogen and phosphorus, finally possessing some defined characteristics of elements ecological stoichiometry. So the ecological stoichiometry of major elements in plants represent the response and adaptation of plants to changeable environment in another way. The ecological stoichiometric characteristics of carbon, nitrogen and phosphorus in response to some major abiotic environmental factors (including soil nutrient, CO2, water, light and temperature) influencing the plant growth were summarized in this review, as well as its possible mechanisms. Besides, the spatial and temporal variations of ecological stoichiometry of carbon, nitrogen and phosphorus in plants were also analysed and studied.
