Middle lamella lignin concentration (MLLC) was measured for 10 clones (cuttings) of Pinus radiata, grown in New Zealand, using interference microscopy. Significant variation was observed among clones suggesting a genetic component to this aspect of lignin distribution. The clonal repeatability, an estimate of broad-sense heritability for MLLC, was 0.70 with a clonal coefficient of variation of 9%. The average MLLC was 69% v/v with a minimum clonal average of 58% and a maximum of 77%.
