“…2c), and have also been observed in other in vitro cultured species capellades et al 1990). In some instances, they were considered the result of an arrest of developing stomata in early phases of differentiation (Koshuchowa et al 1990). Wax deposits increased progressively on both surfaces during the acclimatisation period (Fig.…”

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 µM), 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.

Cultures in vitro of Betula pendula Roth were subjected to light of different spectral qualities. Photosynthetic capacity was highest when the plantlets were exposed to blue light (max recorded photosynthesis, 82 /~mol CO2 dm -2 h -t) and lowest when irradiated with light high in red and/or far-red wave lengths (max recorded photosynthesis, 40 #mol CO2 dm -~ h-~). Highest chlorophyll content (2.2 mg dm -2 leaf area) was found in cultures irradiated with blue light, which also enhanced the leaf area. Morphometric analysis of light micrographs showed that the epidermal cell areas were largest in plantlets subjected to blue light and smallest in those subjected to red light. Morphometric analysis of electron micrographs of palisade cells, showed that the functional chloroplast area was largest in chloroplasts of leaves subjected to blue light and smallest in those exposed to red light. We suggest that light quality affects photosynthesis both through effects on the composition of the photosynthetic apparatus and on translocation of carbohydrates from chloroplasts.
