Abstract
The species Plantago major L. can be divided in two groups of genotypes which differ in relative growth rate: P. major ssp. pleiosperma Pilger, usually found in disturbed habitats, has the highest growth rate. The relatively slow growing genotypes, P. major ssp. major, occur in more stable habitats. The difference in relative growth rate of two lines representing both groups was explained by a difference in morphology: the leaf area ratio and specific leaf area were higher for the fast growing inbred line. The slow growing line had a higher net assimilation rate and photosynthesis per unit leaf area. The higher percentage of dry weight of the slow growing inbred line could not be explained by differences in sugar or starch concentration.
