Abstract

Stomatal resistances and turgor pressures were measured during a 12-day period on leaves of bean (Phaseolus vulgaris L. cv. Contender) which were treated with kinetin, were salinized or were treated with kinetin and salinized. Stomatal resistances were highest in salt-stressed plants, and progressively lower in salt-stressed and kinetin-treated plants, control plants, and kinetin-treated plants. Turgor pressures were highest in salt-stressed plants, and progressively lower in control plants, kinetin-treated plants, and salt-stressed and kinetin-treated plants. Stomata appeared to be kept open more widely under kinetin treatment than under control conditions, even when turgor pressures were lower in kinetin-treated plants than in control plants.
