Presentation of initial research on your species
Working in groups of three, you will select a study species and email me the initial research on your species and your experimental plan. It should include the following information:
Species (and/or cultivar) name, family name, common name(s)
Plant type and life cycle ‐ is your species a perennial herb, shrub or tree? Is it evergreen or deciduous? You can access the online teaching video “Describing plants in designed landscapes” to review your understanding of these concepts.
Relevant background to the species; for instance, what horticultural value does it offer?
Type of materials used for propagation in published studies
Time of year that propagation is typically carried out for your species
Use of plant growth regulators (PGR), most likely auxins such as indole‐3‐butyric acid, indole‐3‐acetic acid, or α‐naphthalene acetic acid in promoting adventitious root formation;methods of application e.g. quick dip into solution of PGR or long soak, and range of concentrations used
Your proposed experimental design for this trial. You’re expected to use a minimum of three replicates of 6 cuttings of any one type for each experimental treatment. You must include a control set of cuttings (i.e. no treatment). You have the option of using different types of stem cutting material. For instance, you might try one of the following:
o Test different types of cutting materials with a limited range of auxin treatments
o Trial a single type of cutting with a broader range of auxin concentrations
o Investigate a single type of cutting material with a single auxin concentration delivered in different ways (quick dip vs. long soak).
Your experimental design should be based on what you’ve found in the literature for your species, or other members of the genus with similar origin, life form etc.
Final report writeup
Your final report will contain the following:
Introduction that provides background to your chosen species and methods of propagation
Methods that explain what you’ve done, including the materials used, the conditions in the propagation house, and the duration of the trial
Results section that outlines your findings quantitively, using graphs or tables. Refer to each of your figures and tables in the text. Add value by including photographic images of your trial outcomes. Each figure should have an informative legend/caption (below it) and each table should have an informative title (above it). Make sure you know how to present these properly and that you refer to figures or tablesin the text. Please look at the suggested referencesif you’re not familiar with the conventions of writing a scientific paper: we will discuss the writeup in class. While graphs and tables are certainly helpful forsummarizing data, photos are also useful to show examples of different treatment outcomes
Discussion in which you explain your findings in relation to the published literature, and provide some suggestions for approaches to propagation of this species in future.
