The unit consists of two modules. The crop physiology module covers physiology of plant growth and development at whole plant level and relates that to the morphology and structure of plants with emphasis on important agricultural plants. Topics include factors affecting seed dormancy, germination, and seedling development, hormone physiology, transpiration, photosynthesis, stress physiology and mineral nutrition. In the ecology module the principles of ecological theory and the application to specific problems in agriculture are covered. Examples to illustrate principles are drawn from natural environments and agriculture ecosystems with an emphasis on Australia. On the completion of this unit students will have a good understanding of fundamental agriculture ecology and crop physiology.
