    ASSESSMENT OF GERMINATION AND EARLY GROWTH TRIAL OF Gmelina arborea (ROXB.)
    (Department of Forestry, Nasarawa State University Keffi., 2015-09-26) Egbewole, Z.T.; Elabora, A. A.; Akinyemi, O.
    The Gmelina arborea is a multi-purpose tree used daily by the forest industries for pulping, light constructions, furniture's and rural communities as fuel wood. a field experiment was carried out to investigate the provenance germination and early growth trial of Gmelina seedlingd. one thousand eight hundred seeds were sourced from 3 different locations namely Akwanga, Nasarawa Eggon and Lafia for germination tests, while 270 seedlings were examined for growth performance. The study was laid in a 3 x 3 factorial experiment in a completely randomnized design, Analysis of Variance was performed to show the the comparative performance of each treatment. Duncan's Multiple Range test (DMRT) was applied to locate where the significant difference occur among the locations and treatments in the measured variables. The result of germination with respect to locations revealed that Akwanga recorded the highest germination percentage of 70.09+- 25.70%, Nasarawa Eggon 66.90 +- 25.24% and Lafia 64.04 +- 22.20%. Also with respect to treatment ,it revealed that( T2- Sundried for 72hrs and soaked in water for 72hrs) recorded the highest germination with 66.61+22.33* uud (T3,Control, 65M±27.24*. The result of growth variables revet****. ^ ^ height of Gmelina arborea seedlings after 12 weeks was 62.04±38.50cm. colla, girth— 14.80+7.13 and leaf area 210.06 +142.84cm\ However, analysis of variance showe^ was a early growth variables assessed at p<0.05.
