Testing New Provenances of Eucalyptus polybractea: A Eucalypt Oil Mallee Adapted to Semi-Arid Environments

چکیده
Novel genetic accessions of Eucalyptus polybractea from a previously untested, hotter and drier part the species’ natural range were tested in common garden trial at semi-arid site NSW, Australia. is mallee eucalypt cultivated for essential oils (1,8-cineole), bioenergy carbon sequestration on dryland sites southern Australia (sites receiving about 450 mm mean annual rainfall, MAR). A six untested provenances relatively hot, dry South (SA) (250–450 MAR) was established alongside seven New Wales (NSW) Victoria within commercial plantation NSW. The assessed age 3.7 years growth oil characteristics. While survival excellent, most SA sources slower growing sub-standard concentration quality relative to those However, single provenance, with highest 1,8-cineole percentage all tested, may have potential as source selected germplasm. Infusion material into breeding populations E. polybractea, which are currently based NSW Victorian selections only, provide more resilience face temperatures expected under projected climate change scenarios, and/or allow introduction species climates or other parts world climates. high-intensity selection infusions will be required maintain characteristics existing population.

Fuel and fire behaviour in semi-arid mallee-heath shrublands
An experimental burning program was set up in South Australia aimed at characterizing fuel dynamics and fire behaviour in mallee-heath woodlands. Fuel complexes in the experimental area comprised mallee and heath vegetation with ages (time since fire) ranging from 7 to 50 years old. Dominant overstorey mallee vegetation comprised Eucalyptus calycogona, E. diversifolia, E. incrassate and E. lept...

A protocol for the micropropagation of Eucalyptus polybractea R.T. Baker (blue mallee) using axillary bud proliferation from lignotuber-derived explants is described. Three different ages of plants were used as explant sources: glasshouse-grown seedlings, field-grown saplings, and coppice of field-grown mature lignotubers. Explants from each source initiated successfully and no significant diff...
متن کاملForage yield and quality of barley-annual medic intercrops in semi-arid environments
On-farm production of protein is limited in most dairy farm operations in arid and semi-arid environments. Cereal-legume intercropping could be a viable option to obtain forage with higher protein content. A two-year experiment was conducted during 2009 and 2010 growing seasons in a loamy soil to determine whether intercropping pattern of barley (Hordeum vulgare L.) and annual medic (Medica...
