Abstract
To study the effect of calcium on wood formation, poplar plants (Populus tremula L. x Populus tremuloides Michx.) were grown for six weeks under different calcium regimes. Energy-dispersive X-ray analysis (EDXA) revealed a decrease of calcium ions in the cambial zone under calcium deficiency. Using light microscopy, a strong impact was shown on the cambial and xylem elongation zone under calcium starvation. By Fourier transform infrared (FTIR) spectroscopy performed on wood and bark cells grown under calcium starvation, we detected a reduction of several absorptions, such as methoxy groups from S-lignin. In conclusion, our results show a distinct influence of calcium on wood formation and chemistry. Hence, efficient tree calcium supply can be considered a decisive factor in xylem production.
