Potential Of 10 Types of Eucalyptus Clones in The Concession Area Pt Tpl Tbk Simalungun Indonesia (Wood Potency Of 10 Eucalypt Clone in Tpl Ltd Forest Consession, Simalungun of Indonesia)

A researched 10 clones of Eucalypts were done in Toba Pulp Forest in 2 sectors of Aek Nauli and Tele as the representative plots. The aim of this research is to know the prospective species in wood producing to be plant at the second period. Research method of inventory of stand by circle radius plot of 11.28 m (0.04 ha) with 3 replications summarized plot broaded about 1.2 ha. The results of the research shown the relation of trees number to average of diameter as mathematical linear regression Dp = 4.218 + 0.007 Np with correlation coefficient (r) is 0.579 and determination coefficient (r2) is 0.336; The relation of trees number to average of Height as a mathematical linear Hp (m) = 4.218 + 0.007 Np (btg) with correlation coefficient (r) is 0.579 and determination coefficient (r2) is 0.336; The relation of trees number to average of bole area (BDp) as a mathematical linear regression BDp (m2) = 16.961 – 0.003 Np (stand) with correlation coefficient (r) is 0.294 and determination coefficient (r2) is 0.087 and The relation are of trees number (Np), averaged of diameter (Dp) and averaged of height (Hp) in to the woods volume (Vp) as a mathematical linear Vp (m3) = - 450.636 + 0.157 Np + 32.409 Dp – 2.199 Hp with correlation coefficient (r) is 0.933 and (r2) determination coefficient is 0.871. Based on the wood analysis volume analysis can be resumed that 3 IND eucalypts clones are recommended for planting the next period, namely IND 61, IND 60 and IND 11. 087 and the relation are of trees number (Np), averaged of diameter (Dp) and averaged of height (Hp) in to the woods volume (Vp) as a mathematic linear Vp (m3) = - 450.636 + 0.157 Np + 32.409 Dp – 2.199 Hp with correlation coefficient (r) is 0.933 and (r2) determination coefficient is 0.871. Based on the wood analysis volume analysis can be resumed that 3 IND eucalypts clones are recommended for planting the next period, namely IND 61, IND 60 and IND 11. 087 and the relation are of trees number (Np), averaged of diameter (Dp) and averaged of height (Hp) in to the woods volume (Vp) as a mathematic linear Vp (m3) = - 450.636 + 0.157 Np + 32.409 Dp – 2.199 Hp with correlation coefficient (r) is 0.933 and (r2) determination coefficient is 0.871.
