Aspects of Crop physiology

Crop physiology can be discussed under the following aspects :

  • Physical aspects: biophysical phenomenon, soil water relation, absorption and translocation of water, transpiration, ascent of sap, guttation etc.
  • Metabolic aspects: enzymatic activities, photosynthesis, respiration, carbohydrate, protein, lipids and nitrate metabolism.
  • Growth and development aspects: seed dormancy, vernalization, photoperiodism, seed germination, growth and development, growth hormones, flowering, senescence.
