SUMMARY

Heterotrophic plantlets obtained by in vitro propagation are biochemically different compared to autotrophic plantlets. When heterotrophic plantlets are transferred to ex vitro conditions, higher irradiance levels are generally applied. Irradiance levels higher than those used in vitro lead to oxidative stress symptoms that can be counteracted by CO^sub 2^ concentrations above normal. We analyzed the stability and activity of Rubisco and leaf-soluble sugars and starch contents ...
