Abstract
Growth of spring barley stands was followed in various conditions. Disposition of the seeds parameters the morphogenetic programme of each individual plant, which will afterwards form the stricture of the young plant stand. Later, individual stopping of tillering is controlled by this stricture. In return, the distribution of these events conditions the structure of the canopy during the shoot lengthening period. In sparse or patchy canopies, weak tillers in stopping of growth are able to survive temporarily.
The plant is not reducible to the genotype of its variety. Individual whole plant and plant stand are true organization levels in an ecosystem. It is essential to take their relationships into account throughout the growth for understanding the behaviour of a crop.
