Stomata are the pores which surrounded by two guards cells which play an important role in regulation of plant water balance and gas exchange between plant internal tissues and the atmosphere. The research involved the examination of variations in stomatal traits: stomatal density (SD), stomatal length (SL), stomatal width (SW) and stomatal surface (SS) based on changes in the plant growth parameters in different growing media in corn. All growth parameters studied was found significant differences between combination rates in both of growing media. The stomatal parameters were changed related to the growing parameters. The increase in leaf growing parameters led to increase in SW, SL and SS values but decrease in SD. It can be said that the SS of corn plant leaf set by changing both of the SW and SL sizes, acting positively on growth conditions. It can be suggested to combine the results obtained from maize with other uninvestigated plant and growth condition to clarify mechanisms of stomatal which are undercontrol of genetic and environmental factors.
