Other claims from this paper (10)
- Observation Wood density remained more or less constant from pith to bark within individual teak trees.
- Observation Wood density varied between the two sampled sites, Sylhet and Rangamati.
- Association Vessel proportion is negatively correlated with wood density in teak.
- Association Ray proportion is positively correlated with wood density in teak.
- Observation Tissue proportions varied conspicuously in narrower rings.
- Observation Tissue proportions were more stable in rings wider than 2mm.
- Observation Differences in wood density between juvenile and mature wood in teak were small.
- Observation Wood density is estimated not to be affected by initial radial growth or initial spacing in teak.
- Recommendation Teak should be grown maintaining ring width above 2mm and selecting trees with higher ray proportions to improve wood density.
- Recommendation Proper site selection is the first and most important step when planning quality teak with higher wood density.
