Intraspecific competition is a competition between members of the same species and is commonly observed in crop plants. Table 6.2 shows the results of a greenhouse experiment which examined the effects of density on the germination and growth of barley. Plants were grown for two weeks in 10- cm diameter pots kept in identical environmental conditions and watered regularly. At the end of the experiment the plants were cropped by cutting the stems at the soil surface. In the given context, can you explain thoroughly the meaning of plant density that this passage is talking about?
