Assessment of the applicability of wood anatomy and DNA barcoding to detect the timber adulterations in Sri Lanka.

ABSTRACT: The wood adulteration is a common problem and under-studied aspect in the timber industry of Sri Lanka. Hence we conducted a survey to assess the status of timber adulteration and check the applicability of morphometric parameters and DNA barcoding to detect the adulterated timber sources. We interviewed the stakeholders of the timber industry to collect information regarding timber adulterations. We measured the morphometric parameters; wood density and sizes of the xylem elements of the standard and adulterant species. For DNA barcoding, DNA was extracted from the wood of the selected standard and adulterant species and subjected to PCR using the markers, matK-trnT and atpB-rbcL. The PCR products were subjected to DNA sequencing. According to the survey, 92.5% of patrons, 73.7% of manufa
