Influence of different cytokinins used in in vitro culture on the stoma morphology of pistachio (Pistacia vera L. cv. Siirt)

Abstract

Three different cytokinins (BA, kinetin and TDZ at 1 mg/l) were tested in order to study their effects on pistachio stoma morphology. Additional BA concentrations of 0.25, 0.625 and 2 mg/l were also tested.
The stoma morphology of pistachio leaves in vitro was affected by cytokinins. Stomas obtained from 1 mg/l BA medium were similar to those developed in vivo. TDZ, kinetin and other BA concentrations resulted in abnormal stoma development.
