Abstract:The mechanism of phytocoenosium stability could be interpreted with the redundancy theory.Redundancies of a phytocoenosium consist of organ redundancy in a plant,redundancy of genetic structure(or individuals)in a population,and species redundancy and layer redundancy at community level.These redundancies maintain relative stability of phytocoenosium.The resistance of phytocoenosium to perturbation derives from species redundancy in a phytocoenosium and redundancy of genetic structure in a population,but re...
