However, the attacked of P. sanguineus were less effective with 31.42%, 18.24% and 10.53% in control samples to 3.71-10.18%, 5.74-14.59% and 4.37-17.08% at the bottom, middle and top portions.

Logging activity is one of the most important activities for tropical coun-tries including Malaysia, as it produces quality trees for papers. 1993). Borne on very acutely angled, glabrous and stout, are dark green, glabrous on a glabrous pulvinus 0.6-1 cm, long. When planted for pulp and paper purposes Acacia mangium is often harvested after just 6 years of growth, a factor popular with that industry. The phyllodes are characterized by four (rarely three, or five) main longitudinal nerves, basally confluent but dis-, tinct from lower margin, minor nerves strongly anatomiz-, ing to form a prominent reticulum (Maslin and McDonald, 1996). The treated wood may, not give good performance in ground contact. 2011). It is reported to grow 3 m tall in the 1st year in Sabah and Sumatra, and in the Philippines it reached Acacia mangium plantations account for more than 50 % of the exotic plantations in Vietnam. Fast-growing A. mangium, which develop a soft stalk and lush foliage were reported to be Planting aeroponic Acacia mangium seedlings 477 fragile for handling and sensitive to desiccation. and Swietenia mahagoni (L.) Jacq, Does stand thinning influence wood physical properties? With respect to distance from the equator, there are significant differences in performance under cultivation. measures should be employed (Hutacharern 1993). This fast wood growing species, however, has some disadvantage in which the wood contains a high proportion of juvenile wood and poorly developed heartwood particularly at the ages between 14 to 18-year-old [1]. However, its deployment must be supported by an understanding f how clones respond to differing environment conditions. Higher phosphate levels and less competition appear to en-, inant stems increased as mean tree volume increased, sug-, gesting a relation to conditions favoring faster growth, rates. Wood properties are influenced by stand management practices like thinning, pruning, etc. [8], Acacia mangium trees produce sapwood and heartwood. Leaves with fruit pod at canopy in Kolkata, West Bengal, India. signed for forest tree seeds. competition, and use of oversized spindly seedlings. 1995. with the phenological recordings, climate was monitored in detail at both the regional and the local scale. ter before or after filling is recommended (Sharma et al. Therefore, the study revealed that the compost of both FS and FW can be a good soil conditioner for the initial growth of forest seedlings and the proven combinations can help to grow quality seedlings in the nursery. al., , 1994Andr e et al., 2005;Brockwell et al., 2005;. Sedgley et al. perimental hybrid seed orchards have been established in, Indonesia. The tree is even grow well in barren dry landscapes with out any special care. ing from the Moluccas islands in Indonesia to W, ural habitats have been identified and studies have shown, ferences in growth rate, stem straightness and frequency of, multiple leaders. This manual, ‘ Acacia mangium Willd. Soil depth and topographic position can influence yields. High DBH MAI val-, ues (more than 4 cm/year) are recorded for stands less than, 3 years old and after this age the diameter MAI v, erally decline towards 1.5-2 cm/year. Scharai-Rad M, Kambey E. 1989. Due to its rapid growth and tolerance of very poor soils, A. mangium was introduced into some Asian, African and western hemisphere countries where it is used as a plantation tree. Compared with other species, A. mangium is fastgrowing, tolerant of nutrient-poor soils and is adapted to a wide range of acidic soils in moist tropical lowlands, ... Twenty five trees from each block are chosen randomly. Twenty year old A. mangium was subjected to stand thinning at 7th year and the effect of thinning was assessed after 13 years.
