Does Air Relative Humidity During Growth Condition Photosynthetic Characteristics of Coffee Leaf ?
Coffee grows naturally in the understory of the wet tropical forest and bears some physiological characteristics of a shade plant (1). Air humidity is certainly an important factor in the development of the plant,but the basic information on this topic is very short. In sequence of previous work (2) this, presents more data showing that low air humidity is a stress factor on photosynthesis and suggests that it affects not only stomatal conductance but chemical characteristics of the mesophyll related with photosynthesis.
