Abstract

Stomata are the primary anatomical structures involved in water loss and gas exchange in plants. Genetic differences in stomatal frequency may have potential in breeding for increased photosynthetic or water-use efficiency. Miskin and Rasmusson (1970), for example , found that barley lines with low stomatal frequencies transpired less water than lines with high stomatal frequencies, with no observed difference in the rates of photosynthesis.
