The transpiration and photosynthetic characteristics of ginger tes-t tube plantlets during transplantation and accl-i
mation were measured and analyzed with a TPS- 1 photosynthetic system ( PP Systems, UK) . The results showed that the
apparent quantum yield, net photosynthetic rate and carboxylation efficiency of the plantlets increased substantially but the
transpiration rate and stomatal conductance decreased during the acclimation after transplantation. These results indicated
that acclimation could greatly improve the capabilities of the plantlets to adapt to natural environment and their autotrophy.
