A new wilt and die-back disease of Acacia mangium associated with Ceratocystis manginecans and C. acaciivora sp. nov. in Indonesia

Some Acacia species native to Australia and neighbouring countries are significant in the rural economy of many countries. Aspects of the domestication process and uses of A. mangium, A. crassicarpa, A. mearnsii, A. saligna and A. colei are reviewed. Commercial plantations of A. mearnsii in tropical highlands and temperate areas provide high quality tannins for adhesives and leather making and wood for paper pulp, rayon, charcoal and small-utility timbers. Plantations of A. saligna in warm-temperate and semi-arid areas provide stock fodder, soil stabilisation, fuelwood and charcoal. In the humid tropical lowlands of South-east Asia, pulpwood is produced in extensive plantings of A. mangium and in smaller-scale plantations of A. crassicarpa in Indonesia. The human food value of seeds of some dry-zone Australian acacias, such as A. colei, is recognised. Domestication of these and other Australian acacias is at various stages and is influenced by the characteristics of the species, extent of planting and the commercial value of the products. The potential for many acacias to become weeds is recognised. The case studies highlight a number of important aspects in domesticating acacias. SB n ve A an acac S.d Jr

Cryptic speciation and host specificity among Mycosphaerella spp. occurring on Australian Acacia species grown as exotics in the tropics

This manual provides methods for the development and evaluation of criteria and indicators (C&I) which can then be used to assess the sustainability of forest management. The manual is written primarily for researchers, people or groups interested in evaluating C&I for assessments of forests in new areas, or as a reference for readers wanting to know how CIFOR's Generic Template was produced. The methods presented are aimed at the development of sets of C&I for natural forest at the forest management unit level, especially in the tropics. Following an introductory chapter focusing on the overall purpose, specific objectives, and the C&I development process, three chapters explain how to prepare for C&I testing, how to conduct a test, and how to analyse the results. Subsequent chapters explain the conceptual basis of C&I development, with three case studies offered as examples, and suggested additional reading materials. Specific forms and tools that have been used in the course of CIFOR's testing are also presented, with examples of ways to present the results. The final chapter provides possible baseline sets of C&I, available to users for evaluation and testing in their own contexts.

Diseases of tropical acacias in Northern Queensland

Fungi associated with stored seeds of Eucalyptus pellita were examined and differences in seed germination, seedling mortality and fungal infection for different provenances were determined. A total of 40 fungal species representing 17 genera of Deuteromycotina, four of Ascomycotina and three of Zygomycotina was identified. Of the 40, 26 were seedborne fungi. Several leaf pathogens were found. There were no significant differences in the level of fungal infestation between provenances, but significant differences in seed germination, seedling mortality and fungal infection occurred when seed lots were inoculated with fungi. Seed lot 17854 from Indonesia and 18197 from Papua New Guinea were less affected with regard to seed germination and seedling mortality than the Australian seed lots 18749 and 18775. The inoculation test showed that Aspergillus niger, Harknessia fumaginea and Pestalotiopsis disseminata were able to reduce germination and cause seedling mortality of some seed lots of E. pellita. Drechslera australiensis caused maximum mean seedling mortality (23.65%) but had no effect on seed germination for any seed lot and Syncephalastrum racemosum affected neither seed germination nor seedling mortality.

Mycoflora and pathogenicity of fungi present on stored seeds from provenances of Eucalyptus pellita

Investigation of mycoflora and pathology of fungi present on stored seeds of Australian trees.

Seiridium eucalypti is recorded and described from eucalypt cankers for the first time from Australia. The species concept is broadened based on this collection. Pathogenicity tests with seedlings of six Eucalyptus species indicated that S. eucalypti was the most pathogenic canker fungus of five tested fungi.
