The synchronization of morphophysiological indexes (plant height, stem diameter, fresh and dry weight, range of electric response to light, etc.) in plants of a cenose (group) has been studied, the corn lines and hybrids with differing competitiveness as well as some model objects being used as examples. The competitive genotypes have been found to be characterized by a better synchronization (a lower coefficient of indexes' variation) and a stronger relationship between the plants of a given cenose (the reduced electric resistance of root contacts) as compared to genotypes with no competitive ability. Electric and electro-magnetic channels of plant interaction in a cenose cansidered as the oscyllators' system have been discussed
