Abstract

in vitro plants are grown in an artificial environment, this leading to the development of a number of physilological characteristics. In This experiment the growth and photosynthetic performance of WILD CHERRY (Prunusavium) cultured under different growth conditions, both in vitro and ex vitro (after 2 and 4 weeks)were investigated. Maximum photosynthetic rate (Pm) for in vitro plantlets was 1.3 micromol. CO2 m-2 s-1. Pm increased approximately 4 fold, two weeks after being transferred into ex vitro, as compared to originally ex vitro plantlets. In this experiment leaf biomass accumulation and leaf area in vitro were lower, as consistent with Pm. No relations were found between Pm, leaf chlorophyll (a+b) content, and a:b ratio. Both a low RUBISCOactivity and a reduced electron transport capacity of in vitro plantlets underlie the low Pm. Since the leaf nitrogen concentration of in vitro plantlets was significantly higher than that of plantlets grown ex vitro it canbe assumed that RUBISCO activity rather than amount of this enzyme limits the Pm of in vitro plantlets.
