The relationship between leaf stomata and yield of upland rice cultivars collected from different altitudes was studied with the electron microscope scanning techniques. The results showed that the number of stomata and the percentage that stoma area accounted for on leaf surface were closely related to the natural altitude. The number and size of upland rice cutivars from higher altitude was larger than that of cultivars from lower altitude. The density of stomata was closely related to the yield of upland rice cultivars. It was suggested that the differences of stomata among the cultivars from different altitudes were ecological and physiological adaptability, and resulted from the genetic mechanism responding in the historical development
