CSES 7256 Crop Physiology


In crop physiology, students will gain an in depth understanding of integral crop physiology functions of photosynthesis, respiration, water relations, photosynthate/solute transport, plant mineral nutrition, and regulation of plant growth & plant growth hormones.

In this course, students will learn about:

  • The light reaction, the light independent (i.e. dark) reaction, efficiency of photosynthesis (various ways to calculate and compare), photosynthesis efficiency in response to environmental factors, inhibition of photosynthesis by herbicides (4 ways)
  • Converting energy storage compounds back into ATP, difference in respiration between ‘wild’ and crop plants
  • Plant tissues involved in water movement, water ‘potential’ and the physics involved in water movement from soil, through the plant and into atmosphere, why plants have to transpire so much water, how plants respond to temporary drought, how plants adapt to long term drought, i.e. arid conditions, variations in water use efficiency (WUE) between crop plants, relationship between WUE and photosynthetic and carbon fixation pathway, how can crop plants be breed and/or engineered to be more drought tolerant?
  • Plant tissues involved in solute transport, active versus passive transport; phloem loading, assimilate partitioning and the source-sink relationship of transport, variations in assimilate transports and partitioning and crop yield
  • Absorption and translocation of mineral salts, plants have only marginal selectivity of minerals absorbed, why plants can absorb worthless or even toxic substances, function, absorption, mobility and deficiency of the essential macro mineral elements, N,P,K, Ca,Mg, S, Ck, function, absorption, mobility and deficiency of the essential micro mineral elements; Fe, B, Mn, Zn, Cu, Ni, and Mo, how plants compensate for limited availability, ecto/endo mycorrhiza, chelation of selected micronutrients, agricultural practices that compensate for limited absorption and/or mobility.
  • The know plant hormones their effects on growth and development, agricultural products based upon plant hormones

Each student will be required to complete three examinations and participate in discussions.
