Description This subject aims to provide knowledge of relationships between plant growth, controlled environment and crop physiological aspects relevant to protected crop production. The subject will provide students with relevant knowledge to explain and develop concepts that are key to understanding various areas of environmental plant physiology. The subject will also stimulate students to conceptualise interactions between the physical environment and plant functioning. The subject will compare the important parameters and concepts (e.g. plant growth, plant and fruit development, light interception, light use efficiency, biomass partitioning, and water use efficiency) in horticultural crop growth in the controlled systems.
