Eco-Physiology

Preliminary Notions. Factors affecting plant growth.


Plant growth results from both endogenous processes and environmental factors.

The endogenous process

    The endogenous process: plant structure establishment
    Plant structure establishment is the final result of the endogenous process.

      The differentiation and production of the various organscan be expressed from rules applied to successive metamers.

      Such rules can be simulated with an automaton.

      In the illustrated example the structure is built from five consecutive metamers at the same stage of differentiation.
           The terminal bud then reaches a flowering stage; the growth is thus determinate.        (Drawing and animation P. de Reffye, CIRAD)
    		    Plant organogenesis raises from an endogeneous process.
