Inroducton: Plan sress 

Plans are rarely under optmum environmenal conditons, and are subeced o siuatons where hey are forced beyond he optmum limis!



"he sudy of plans under hose conditons is #nown as plan sress physiology!



Stress is usually dened as an exernal facor ha exers a disadvanageous in$uence on he plan! "hese can be environmenal or abiotc facors ha produce sress in plans, alhough biotc facors such as weeds, pahogens, and insec predaton can also produce sress! In mos cases, sress is

measured in relaton o plan survival, crop yield, growh %biomass producton& or he primary assimilaton processes %'( ) and mineral upa#e& which are relaed o overall growh! Taiz and Zeiger, 2010. 

Plans respond o sress conditons by modifying heir physiology and meabolism!

Climac stress:



Stress linked to crop cycle:



Water



Trasplant



Light



Sprouting



Salt / pH



Flowering



High / low temperature



Fruit set



Heavy metals / Nutrients



Fruit growth



Pollutants



Other stress:



Plant damages



Phytotoxicity due to pesticides application

If record yields can be assumed o represen plan growh under ideal conditons, hen he losses associaed wih biotc and abiotc sresses can reduce the averae producvity !
