Seedling Responses of Three Australian Tree Species to Toxic Concentrations of Zinc in Solution Culture

Seedling responses of three Australian tree species to toxic concentrations of zinc in solution culture S. M. Reichman1,C.J.Asher2, D. R. Mulligan1,3 & N. W. Menzies2 1Centre for Mined Land Rehabilitation, The University of Queensland, Brisbane, 4072 Australia. 2School of Land and Food Sciences, The University of Queensland, Brisbane, 4072 Australia. 3Corresponding author∗ Received 12 July 2000. Accepted in revised form 28 May 2001 Key words: Acacia holosericea, critical concentration, Eucalyptus camaldulensis, Melaleuca leucadendra, solution culture, zinc toxicity Abstract A frequently desired outcome when rehabilitating Zn toxic sites in Australia is to establish a self-sustaining native ecosystem. Hence, it is important to understand the tolerance of Australian native plants to high concentrations of Zn. Very little is known about the responses of Australian native plants, and trees in particular, to toxic concentra- tions of Zn. Acacia holosericea, Eucalyptus camaldulensis and Melaleuca leucadendra plants were grown in dilute solution culture for 10 weeks. The seedlings (42 days old) were exposed to six Zn treatments viz., 0.5, 5, 10, 25, 50 and 100 µM. The order of tolerance to toxic concentrations of Zn was E. camaldulensis> A. holosericea> M. leucadendra, the critical external concentrations being approximately 20, 12 and 1.5 µM, respectively. Tissue Zn concentrations increased as solution Zn increased for all species. Root tissue concentrations were higher than shoot tissue concentrations at all solution Zn concentrations. The critical tissue Zn concentrations were approximately 85 and 110 µgg−1 DM for M.

Blake (Myrtaceae), known as paperbark, punktree, native Australia except South Australia (Burkhardt 1991). or melaleuca, is an aggressive invader of many South Specimens released in Florida originated from southeastern Florida ecosystems, including the Everglades. Melaleuca is Queensland. As of October 2002, the melaleuca psyllid had considered a pest because it displaces native vegetation and been released in five Florida counties—Broward, Collier, degrades wildlife habitat; it also creates fire hazards and can Lee, Miami-Dade, and Palm Beach—and is known to have cause human health problems (Rayamajhi et al. 2002). The established in all counties except Palm Beach. It eventually USDA/ARS with federal and state permission introduced spread naturally to all 22 central and south Florida counties the psyllid Boreioglycaspis melaleucae (Figure 1) into where melaleuca infestations occur. Broward County, Florida, in February 2002 as a potential biocontrol agent of melaleuca. Description Adults Boreioglycaspsis adults (Figure 2) are small, about 3 mm long, and inconspicuous, pale yellow-orange to white in color with gray to black markings. The tips of the antennae are gray to black, and the wings are transparent with yellow veins. The compound eyes are usually pale green with a distinctive dark spot within, but various shades of red have been observed in the laboratory; its three ocelli are bright orange, the dorsal two being the most obvious.

NEWSL~II ttc NO I4 - JUNE 1991 Firstly, I am going to borrow, in part, a quote from a recent Grevillea Study Groupl Newsletter "A newsletter can only be as good as contributions by members make it. Articles, however small are always welcome". News of your garden or your neighbours or friends garden or details of plants seen or discovered in the wild would make the newsletter more relevant to all. Perhaps you might like to write an article on the establishment and! growth of your garden which could be used in the "Feature Garden" section which,^ unfortunately, is missing from this newsletter as I have temporarily "run out of gardens". I Are you satisfied with the format and content of previous newsletters? If so, please let me, know or, if not, let me have your suggestions as to how you feel it could be improved. Onto more interesting topics. We had good rains here in Jan-Feb 1997 and this appeared to, trigger many of the Callistemons to produce an out-of-season crop of flowers. Callistemoq polandii, which usually flowers around July-August produced flowers in Jan-Feb and again in May. Melaleuca viridiflora and the cream and red forms of Melaleuca quinquenervia have been flowering well for the past few months. These plants will often produce 3-4 crops of blossom during their flowering period which extends from Jan-Feb to around June-July.

One important thing is how to do land reclamation and restore the preservation of the natural environment. Reclamation characteristics are open space, high light intensity, high temperature and extreme fluctuation, low pH and degradation of the number of species both flora, fauna and soil microorganisms. Such characteristics cause not all types of plants can live on the land. Theoretically, the results of the suitability of forest plant cultivation land are specifically eucalyptus plants (Melaleuca leucadendra) and Sengon (Paraserianthes falcataria). This is necessary and important to be studied regarding the limiting factors and management efforts in the former coal mining land. This can provide information and thought contributions to maximize the reclamation activities of former coal mining using plants, which have a high enough sale value, are environmentally sound and sustainable while taking into account local wisdom.

KIMBERLEY TROPICAL MONSOON RAINFORESTS OF WESTERN AUSTRALIA: PERSPECTIVES ON BIOLOGICAL DIVERSITY Kevin F. Kenneally School of Agriculture & Environment, Faculty of Science The University of Western Australia, MOO4, 35 Stirling Highway Crawley, Western Australia 6009, AUSTRALIA Nulungu Research Institute, Notre Dame University Australia, Broome, Western Australia, AUSTRALIA Western Australian Herbarium, Department of Biodiversity Conservation and Attractions (DBCA), Locked Bag 104, Bentley Delivery Centre, Western Australia 6983, AUSTRALIA Western Australian Museum, Department of Terrestrial Zoology 49 Kew St, Welshpool, Western Australia 6106, AUSTRALIA [email protected] ABSTRACT There are more than 1,500 patches of monsoon rainforest, totaling 7,000 hectares, scattered across 170,000 square km of the tropical Kimberley region of Western Australia. They are small, isolated and embedded within a mosaic of mostly flammable eucalypt savanna woodlands. The status and condition of Kimberley monsoon rainforest biodiversity are assessed based on geographically comprehensive survey data from a total of 100 sites and opportunistic collecting in many others. Monsoon rainforests are rich in species not found in the region’s other vegetation communities. Most rainforests and their associated faunal assemblages are not currently reserved and many of the survey sites were found to be severely disturbed by fire and introduced feral cattle. The disturbance impact of fires, introduced animals and weeds is shown to apply generally across the three major forms of land tenure operating in the Kimberley; namely, Aboriginal land (includ- ing Indigenous Protected Areas), Crown land (including pastoral leasehold), and national parks and reserves. The implications of these disturbance factors on the conservation and management practices of monsoon rainforest patches in the region are considered.
