Flowering strength in seedling seed orchard of Acacia mangium was observed in relation to family variation and provenance variation. The flowering strength was assigned visually to one of the flowering categories: 0-none; 1-light ; 2-medium ; 3-heavy. The flowering strength was significantly different among families and provenances. The repeatability of flowering strength was estimated to be 0.256. The flowering strength of lower part of tree crown was lower than that of upper part of the tree crown. Theeffects of stand density and tree size of the seedling seed orchard on flowering strength were examined.
