Type: article
Abstract: Size, density, and stomata opening value in leaves of Actinidia deliciosa shoots cultured in three benzyladenine (BA) concentrations (4.4, 44, and 440 μM ) during different incubation periods at the end of the multiplication, rooting, and acclimatisation phases were measured. A follow‐up of the morphology of both adaxial and abaxial surfaces of the leaves was also performed. The presence or absence of 4.4 μm BA in the culture medium did not affect stomatal size during the multiplication phase, though the increase of the BA incubation period from 30 min to 4h did induce an increment in the stomata transversal axis size. The application of BA (4.4 μ M ), regardless of the incubation period, increased stomatal density at the end of the multiplication phase. When the concentration of BA was increased in the culture medium during the multiplication phase, a decrease in the stomatal opening took place at the end of the acclimatisation phase.
