“…A. mangium from the SE of Daintree showed the lowest survival rate. Generally, the results of the survival rate obtained in this study were comparable with the trends experienced in many of the A. mangium and A. auriculiformis provenances trials in the humid tropics [5] [6] [22]- [25]. The reasons for the low survival rate at the unburned site may be attributed to weed competition, animal trampling and shade.…”

“…Review of Turnbull [1] indicates the extent of Acacia plantations in Asia. In addition, many national and international provenance trials of A. mangium and A. auriculiformis have been reported from different regions and localities such as from China [2], Indonesia [3] [4], Malaysia [5] [6], Thailand [7] [8], Zaire [9] and Vietnam [10] [11]. Reports from Malaysia and Thailand, in particular, indicated that despite their successful introduction and adaptability, both A. mangium and A. auriculiformis provenances grown in plantation and trial sites have shown problems in tree form, growth habit and develop multiple leaders (ML) right from the base of the trunk and in some cases heavy epicormic branching with excessive low forking branch.…”

Loss of apical dominance, resulting in seedlings with more than one leader, generally referred to as multiple leaders (ML), has been a major problem in forest tree plantation in the tropics. A study to examine the effects of site preparation by burning on growth performance and multiple leaders (ML) formation, and its variation in eight-genotypes of Acacia mangium and Acacia auriculiformis was conducted. The design used for this field trial is a randomized complete block design with four replications at two sites (burnt and unburned) and eight genotypes (four from each species), and the effects were monitored for 24 months. There were significant differences at P < 0.05 between sites and genotypes for the number of ML trees/plot, basal diameter and survival. Differences among the genotypes, in terms of height, were also significant, but not between sites. The site × genotype interaction was significant only for ML trees per plot. Generally, the number and the size of ML trees per plot in the burnt site were higher and bigger than those in the unburned site. The number of ML trees per plot formed increased exponentially with time, reaching a peak in about four months after their first occurrence and then leveled off to an almost steady state thereafter at both sites. The average number of multiples (leaders) per tree ranged from 2 to 5 at the burnt site whilst at the unburned site, all the ML trees were of two leaders. A. mangium provenances were more responsive to burning than A. auriculiformis, whereas at the unburned site, the variation between them was not significant. Based on the above variation, it can be concluded that burning causes ML formation and can affect the growth of these selected Acacia genotypes.

“…Significant growth differences were observed: (i) between provenances at four sites, (ii) between the sites, (iii) between provenances within regions. These findings were supported by Ryan et al (1986), Hardwood and Williams (1991), Bhumibhamon (1992), Awang et al (1994), and Tuomela et al (1996). In these studies, there were clear differences between the regions.…”

Asif M.J., Dorairaj D., Wickneswari R. (2017): Characterization of natural provenances of Acacia mangium Willd. and Acacia auriculiformis A. Cunn. ex Benth. in Malaysia based on phenotypic traits. J. For. Sci., 63: 562-576.Acacia mangium Willdenow and Acacia auriculiformis A. Cunningham ex Bentham and their hybrid have become important planting species in Malaysia. Due to their high demand and consumption, development of high quality planting materials is desired. Conventional breeding of Acacia Miller is slow but the utilization of marker-assisted selection breeding can expedite the breeding process. Markers associated with quantitative trait loci (QTLs) required pedigreed populations whereas association mapping can be used directly on diverse germplasm. This study was conducted to screen provenances of A. mangium and A. auriculiformis of different geographical origins for their performance under the Malaysian environment. A. mangium exhibited superior traits compared to A. auriculiformis. More trait variation was observed within and between provenances of A. auriculiformis. Provenances from Queensland (QLD) were superior to those from Papua New Guinea (PNG) and Northern Territory. The best performing provenance with all three superior traits was from Claude River QTL of A. mangium and the worst was Bensbach Western Province, PNG belonging to A. auriculiformis. For individual traits like DBH, Morehead, PNG was superior. For plant height, Morehead, PNG was the superior provenance for A. mangium and Morehead River, QLD was from A. auriculiformis. For stem straightness the A. auriculiformis provenance Jardines Garden, QTL was superior to West of Morehead (PNG) for A. mangium. Multivariate analysis grouped provenances together based on similar traits and genetic similarity. These provenances can be used for seed families which can be treated as a homogeneous population for association mapping or for the development of segregating hybrid populations for Acacia breeding. For the purpose of utilization, provenances of A. mangium can be used for sawn timber. For fuelwood and charcoal industries, A. auriculiformis provenances should be preferred by selecting multi-stemmed trees. The most variable provenances with superior phenotypic traits can be integrated with the genotypic data e.g. single nucleotide polymorphism markers for association mapping to identify quantitative trait loci for marker-assisted breeding.

“…for A. auriculiformis (Awang et al 1994), its magnitude has not been sufficient to make it of major importance for breeders. More or less the same set of superior provenances from each species have been used as base populations for breeding in all major planting regions, from close to the equator (e.g.…”

Three acacia species, Acacia auriculiformis, A. crassicarpa and A. mangium, dominate over 2 million ha of tropical acacia plantations worldwide. Species and provenance trials carried out in the 1980s and 1990s established the fastest-growing regions of provenance for each species, and most current breeding populations comprise open-pollinated families from several, or many, local provenances sourced from these favoured regions. Provenance-progeny trials are thinned to seedling seed orchards (SSOs), which yield both selected progenies for the next generation of breeding and operational seed for plantations. Clonal forestry has been successfully developed for A. auriculiformis and the hybrid between A. mangium and A. auriculiformis. In many instances production of improved seed in seed orchards has not been adequate to meet planting demand; strategies to address this have been (1) the establishment of additional unpedigreed seed production areas of broad and superior genetic base, and (2) clonal family forestry to multiply elite seed families. Controlled pollination of acacias is technically demanding, so is not suitable for advancing main breeding populations. Substantial (50-100%) gains in wood volume production have been demonstrated in trials comparing seed from first-generation SSOs or selected clones with inferior provenances and land races, but volume gains in subsequent cycles of breeding will be smaller. The potential for genetic improvement in form traits and wood properties has also been demonstrated. Genetic improvement objectives must now give heavy weighting to improving disease resistance and tolerance. Ganoderma root rot and Ceratocystis stem wilt have destroyed large areas of acacia plantations in Indonesia and Malaysia. Since clonal deployment of resistant genotypes is the quickest and most effective way of delivering resistant planting material, ongoing research to develop clonal forestry for A. crassicarpa and A. mangium is warranted. Novel interspecific hybrid combinations might deliver useful genetic variation for breeding.
