“…In contrast with research related to a few anatomical properties (Verghese et al 1999; Ishiguri et al 2004; Kojima et al 2009; Chowdhury et al 2009a), detailed anatomical variability along the radius has not yet been determined in this species. In this regard, the objective of this study was to investigate the possibility of plus tree selection on the basis of anatomical properties variations in Acacia auriculiformis A. Cunn.…”

“…The range of the mean vessel and fibre diameters of the present study were similar to Verghese et al (1999), while the fibre wall thickness was lower than that of the previous study. In addition, Ishiguri et al (2004) also showed that the mean vessel, fibre and axial parenchyma proportions were approximately 16·8, 65·0 and 12·0% respectively, in 11-year-old Acacia auriculiformis A. Cunn. (ex Benth) grown in Malaysia.…”

“…(ex Benth) has been planted in China, India and Southeast Asia, and some African countries (Pinyopusarerk et al 1991). The wood of this species is widely used for charcoal, fuelwood, pulp and construction (Pinyopusarerk et al 1991; Ishiguri et al 2004). Owing to its fast-growing nature and good site adaptability, it has been considered a priority species in the short-rotation plantations in Bangladesh, such as social forestry and agroforestry projects (Islam et al 1999).…”

Acacia auriculiformis A. Cunn. (ex Benth) is an extensively planted fast-growing species in Bangladesh. Understanding the anatomical property variation has significant importance in tree improvement and wood utilization. Radial variations of anatomical properties in 11-year-old trees were examined in this study. Vessel diameter increased gradually up to about 40-45% distance from pith and then levelled-off to bark. Fibre diameter gradually decreased toward bark, whereas fibre wall thickness showed a reverse pattern. In contrast to fibre proportion, vessel and ray proportions gradually increased from pith to bark. Cell wall proportion was nearly stable up to y70% distance from pith and then increased gradually to bark. Results suggest that air-dried density or compressive strength variation is mainly attributed by the fibre morphology, i.e. fibre diameter and fibre wall thickness (at 1% level). Significant variations among the trees in vessel and fibre diameters (at 1% level), and ray and axial parenchyma proportions (at 5% level) suggest the possibility of tree selection for breeding.

“…The presence of variability in anatomical characteristics has a profound influence on the wood properties (Dadswell, 1957;Burley and Palmer, 1979). Studies on wood properties in A. auriculiformis have been studied in different ages by Varghese et al (1999), Ishiguri et al (2004) and Shukla et al (2007). However, in India, a few studies were available on genetic variability on growth, density and fibre property in A. auriculiformis.…”

Genetic variability of growth, wood density and fibre characters was determined in twenty second-generation clones of Acacia auriculiformis grown at IFGTB-Field Research Station, Neyvli, Tamil Nadu, India. Total volume revealed high phenotypic (29.10 %) and genotypic coefficient of variation (31.30%). Moderate PCV and GCV values were observed for height, fibre lumen diameter, Runkel ratio, slenderness ratio and wood density. The volume and fibre lumen diameter had high heritability 86 and 76 per cent, respectively. Fibre length, Runkel ratio, slenderness ratio and rigidity coefficient showed high heritability coupled with high to moderate genetic advance. Twenty clones was formed into four clusters by D2 analysis. Maximum inter-cluster distance was recorded between cluster II and cluster IV (7.396) and minimum inter-cluster distance was recorded between clusters II and IV (3.364). Higher intra-cluster values were observed in clusters I (4.171) and lower values in cluster III (3.179). Selection of clones based on clusters provides an opportunity for further improvement of growth and wood quality.

Aims: To determine the impact of Pb on seed germination and early seedling development in A. auriculiformis species. Place and Duration of Study:The study was carried out in Department of Biology, University Putra Malaysia, between April 2016 and February 2017. Methodology: The concentrations of lead from 0 to 4 g/L (interval of 0.5 g/L) were used. Seeds were germinated in vitro condition. Different parameters were measured including germination percentage, seedling vigour index, tolerance index, germination index, mean germination time and relative injury rate. Results: The noticeable finding of this study reveals that A. auriculiformis seeds have the ability to Original Research Article
