Abstract

It appears that phosphorus deficiency in plants drastically affects the ability of leaf stomata to open universally in all plant species, but in varying degrees. Failure of the stomata to open results in greatly decreased water use, and in elevated leaf temperatures. These studies indicate that the increased temperature is the cause of at least some phosphorus-deficiency symptoms.
