Variation in physico chemical characteristics of Toona ciliata M. Roem provenances

Abstract

Toona ciliata M. Roem belongs to family Meliaceae is one of the best known Indian timber species, popularly known as Toon and Red cedar. The aim of the study was to determined physico chemical characters of wood of Toona ciliata collected from three states. The moisture and maximum moisture content (%) and specific gravity were found to be significant variation in sapwood and heartwood of wood parameters. The variation in water and chemical (%) and Alcohol benzene soluble extractives was found characteristics wood samples. Variation in holocellulose and lignin content (%) was found significant variation in different provenances. The wood samples from Uttarakhand found better as per selected parameters in comparison to the chemical characters of wood from Himachal Pradesh and Uttar Pradesh. Conclusion: During this study it was observed the variability in physico chemical characteristics. The two provenances viz Naini and Nauni have been measured percent of holocellulose (74.50) and lignin (28.5) respectively under sharp focus for utilization and deployment for future improvement programme.
