Botany 431 - Physiological Plant Ecology
At the end of your study this week, you should be able to achieve the objectives listed below. You must assemble the evidence that you have achieved these learning outcomes into your Portfolio. You should provide evidence that would be regarded as performance at the top two levels of Biggs' SOLO Taxonomy.
The material in your Portfolio will be assessed as Project 3.
If you wish to discuss this material informally with your peers, you can interact in
Esme's Coffee Shop.
You can also challenge your peers by posting questions for them to respond to on the
Student Quiz Board.
When you have completed this section you will be able to:
- Identify the principle regulatory pigments involved in photoperiodism, phototropism and photomorphogenesis.
- Describe the light requirements (effective wavelengths, durations, orientations etc.) influencing the processes in Objective 1.
- Identify the characteristics of the ambient light and predict its impact on plant growth in the following situations:
- Above an open field at mid-day.
- Above an open field around dawn and dusk.
- Beneath a closed plant canopy at mid-day.
- In a sun fleck beneath a plant canopy at mid-day.
- Evaluate the role of phytochrome in competition between plants.
