  • Abstract:

This study examined the qualities of pulp and paper produce from Ficus exasperatain Bunu Tai, Rivers State, Nigeria. Samples were collected along the axial direction(base, middle and top) along the sampling height. Wood samples for anatomical properties were prepared by trimming of the splinter wood into thin slices(silvers) and placing them in well labeled test tubes containing equal volume (1:1) of 10% Acetic acid and 30% Hydrogen Peroxide. The silvers in tube were o later placed in oven for 4 hours at a temperature of 80 C for bleaching and softening. The chemical mixture was decanted and the fibres were washed with distilled water five times, the fibres were then separated. The experiments were in 2 factor factorial experimental in Completely Randomized Design (CRD) and the data collected were subjected to analysis of variance using the SPSS version 20.0.The results showed inconsistency wood properties sampled as fibre length (FL) at base (1.44±0.41)mm, Middle (1.14±0.21) mm and top (1.344 ± 0.514)mm while fibre lumen diameter highest at top (14.5960±4.806) µm followed by base (13.0790±4.069µm) and lowest middle with 11.0905±3.223µm similarly, fibre cell wall thickness highest attop5.699±1.405µm followed by base 5.217±1.461µm and lowest middle 4.2845±1.097µm. Runkel ratio variation decreased from the base to the middle and thereafter increased to the top: 0.8604±0.357, 0.821±0.250 and0.8320±0.242 respectively. Coefficient of flexibility of the wood was highest inmiddle 55.759±7.962 followed by top 55.5274±7.312 and lowest at base 55.210±8.117 while fibre felting power decreased from the base 64.7998±26.418, followed by middle - 62.141±22.988 and lowest at top - 51.947±16.469. The pattern of variation observed from fibre length, fibre density, fibre lumen, cell wall, Runkel ratio were inconsistent .The species can be recommended for paper production and low construction purposes.
