Wahyudi I., . and Okuyama T., . Relationship between growth rate and growth stresses in Paraserianthes falcataria grown in Indonesia. pp. 95-105. ISSN 1394-2204
Abstract
Growth stresses reflected by longitudinal released strains of Paraserianthes falcataria from plantation trees were investigated in order to study their growth stress mechanism and to evaluate the influence of high growth rate on growth stresses and other wood properties. A total of 21 trees of P. falcataria of various ages and stem diameters from one section of Perum Perhutani man-made forest area in Leuwiliang West Java Indonesia have been utilised. It was found that growth stresses in P. falcataria were lower than in Acacia mangium even though diameter increment of P. falcataria was greater with mean values ranging from 2.0 to 6.1 cm per y. There was no effect of growth rate or tree age on growth stresses. Growth stresses did not change with distance from the pith at 3 to 18 cm with means ranging from -0.03 to -0.08 percent. Higher negative values were correlated with the formation of tension wood. There was no relationship between growth rate and specific gravity. A clear correlation was found between the released strains and the microbial angle (MFA). The smaller the MFA the higher the absolute values of the contractive released strains.
