Degree of synchronization of morphological/physiological indices of plants in a phytocoenosis as a criterion for the evaluation of their competitive ability


Sel' skokhozyaistvennaya Biologiya ( 3): 81-88
Degree of synchronization of morphological/physiological indices of plants in a phytocoenosis as a criterion for the evaluation of their competitive ability
In pot studies with maize lines and hybrids contrasting in competitive ability and grown as single plants and in groups of 5 plants, synchronization of morphological/physiological indices (such as height, stem diameter, fresh and dry weight, and range of electrical response to light) between plants in a group was better, with a lower coefficient of variation in the indices, in the case of competitive genotypes, and there was a stronger relationship between plants of a group (reflected in reduced electrical resistance of root contacts) than in the case of genotypes with poor competitive ability. Rapid methods for evaluating competitive ability are proposed based on the electrical and electromagnetic channels of plant interaction in a community.
