Knowledge Base González, 2006 Nodule formation processes (Burdass, 2002)
5
Knowledge Base Poole, 2006 Rhizobium is the most important bacterial group in nitrogen fixation (Burdass, 2002)
6
Literature Review “Rhizobium- legume Symbiosis” Department of Molecular & Cell Biology Juan E. González Exopolysaccharides (microorganisms) may play a role in nitrogen fixaton
7
Literature Review “Characterisation of Hardenbergia Mosaic Virus and Development of Microarrays for Detecting Viruses in Plants” Murdoch University Craig Graham Webster Potyvirus can cause malformation of legumes such as these cucumbers
8
Purpose/Hypothesis The purpose of an experiment testing the effects of rhizobium on nodulation processes and aphid extermination is to find which specific type or strand of rhizobium, natural or inoculants, will better form nodules, and decrease aphid activity. H(a) suggests that inoculant rhizobium will better form nodules and exterminate aphids
9
Methods Rhizobium Strain Effects On Nitrogen Fixation and Aphid Extermination Natural rhizobium strains N=10 Oil based inoculant rhizobium strains N=10 5-7 days incubation, sub culturing TY plates, growth in media and nodulation Aphids exposed to nodules Nodules formed in effect of inoculant/ natural strains Percentage of aphids exterminated by inoculant/ natural strains ANOVA, Scheffe post-hoc test: inoculants with natural rhizobium (p<.05)
