Rumex tianschanicus × patientia is a high-biomass-yielding plant suitable for fuel and biogas production. The protocol of the hybrid sorrel micropropagation was used to study changes in photosystem II (PSII) activity as well analyse ultrastructure chloroplasts. lowest effective PSII quantum yield [Y(II)] an apparent electron transport rate [ETR(II)] were observed adventitious shoots that had been regenerated vitro, before rooting. These fluorescence parameters higher similar both leaves same rooted under vitro conditions acclimated grown ex conditions. analysis indicated strongly depends on formation properly functioning roots or culture are, at least some degree, less important. TEM revealed chloroplasts from plants sufficiently mature acclimatization processes have impact their development. This first report concerning all stages micropropagation, i.e. shoot rooting acclimation It conditions, rather than plays key role development completely functional photosynthetic apparatus sorrel.
