Abstract:

This study was conducted to determine, if stomata density can be used as a criterion in cultivar differentiation or not.

In this study, density of stomata in stipula and abaxial and adaxial surface of leaflets was determined in the flowering and pod set period of 23 pea cultivars and lines that were sowed as wintertime for 2 years.

The effect of years on the stomata density in other parts sections except for the stomata numbers in stipula and leaflet adaxial surface were determined on the level of statistical significance.

In pod setting period, stomata numbers were higher compared to the flowering period.

Stomata number in leaf section of the 5 cultivars used in the trial is in general higher than those of the lines.

The determination of year x genotype interaction in the study shows that there is not enough evidence for using this characteristic for cultivar differentiation.
