The effects of double, triple and quadruple combinations of gibberellic acid, kinetin, 24-epibrassinolide and polyamines (cadaverine, putrescine, spermidine, spermine) on the stomata movements in the leaves of barley seedlings grown under saline conditions were studied. In the control seedlings, the stomata number, stomata index and stomata length increased in the upper surfaces of leaves in comparison with their lower surfaces. In addition, the epidermis cell number in the leaves of control plants were fewer in the upper than in the lower surface. The width of the stomata was equal in both surfaces. The different substances applied generally decreased stomata number, stomata index, stomata length and epidermis cell number, while they increased the stomata width. Growth regulators may help barley seedlings to adapt to saline conditions.
