Effect Of Carbohydrate Source, Auxin And Endogenous Ethylene Upon Root Induction Of Eucalyptus Marginata Donn Ex Sm. In Vitro, Meredith Magaret Fairbanks
Theses : Honours
The utilisation of eucalypts around the world is increasing, mainly through the development of plantations. Clonal propagation has become important in some countries for production of such plantation trees. Micropropagation has been utilised to produce clones of trees selected for specific characteristics such as disease resistance, salt tolerance and fast growth rates. However, a suitable micropropagation protocol for all eucalypts has not been produced. One component of the micropropagation protocol, in which there is considerable difficulty, is the induction of adventitious roots on micropropagated shoots. Of particular interest, is the development of these procedures for Eucalyptus marginata (Jarrah) that have …
Phenolic And Lignin Concentration As An Indicator Of Resistance To Phytophthora Cinnamomi In Banksia Species, Sandra Jane Nicoski
Phenolic And Lignin Concentration As An Indicator Of Resistance To Phytophthora Cinnamomi In Banksia Species, Sandra Jane Nicoski
Theses : Honours
Phytophthora cinnamomi Rands, a soilborne fungus, is regarded as one of the most devastating pathogens yet recorded in natural ecosystems. The disease, caused by P. cinnamomi, poses an enormous threat to the flora of the southwest. The Proteaceae, in particular, contribute considerably to species richness and provide the fundamental floristic structure of many south-western plant communities. The genus Banksia, a member of the Proteaceae, is very susceptible to disease caused by P. cinnamomi. Three species, namely B. attenuata, B. grandis and B. menziesii. Were established in an aeroponics system under glasshouse conditions. Trials were conducted to optimise growing conditions in …
Development And Optimisation Of A Micellar Electrokinetic Capillary Chromatography Method For The Separation And Identification Of Phenolics From Eucalypt Species, Andrew J. Tromans
Development And Optimisation Of A Micellar Electrokinetic Capillary Chromatography Method For The Separation And Identification Of Phenolics From Eucalypt Species, Andrew J. Tromans
Theses : Honours
Several buffers were examined for their ability to separate a complex mixture of phenolic compounds using micellar electrokinetic capillary chromatography (MEKC). The phenolic mixture included simple phenols, phenolic acids and coumarins. Of the different buffers examined, 6 mM borate, 10 mM phosphate, 100 mM SDS, pH 8.3 gave the best separation. The ability of organic modifiers, complexation agents such as α cyclodextrin, β cyclodextrin and mixed SDS I Brij 35 micelles to improve the separation and peak retention time reproducibility of the buffer system was investigated. Baseline separation of the 18 phenolics was achieved by the 6 mM borate, 10 …
