A Laser Photoacoustic Analysis of Residual CO2 and H2O in Larch Stems
Every so often, the results obtained from investigations into the effects of varying environmental conditions on the tree growth rate at the same sites and on the change in the carbon balance in plants, using traditional methods, are found to differ widely. We believe that the reason for the ambigui...
