Show Summary Details


This chapter presents a review of the variety of morphological and functional features of plant-reiterated structures that exhibit significant amounts of variation within individuals. The focus is to provide just a catalogue of features that exhibit subindividual variation, rather than quantification of such variation. Within-plant heterogeneity in subtle structural, chemical, or functional leaf features is by no means confined to heterophyllous plants exhibiting discrete variation in leaf features. Broad within-plant variation in the number of filled seeds contained in each ripe fruit seems to be the rule among species with multiovulate ovaries. Significant within-crop variation in the concentration of major mineral nutrients may be inferred from some investigations that have examined the relationship between nutrient concentration and seed size in tropical and temperate wild plants.

Keywords: subindividual variation; within-plant heterogeneity; nutrient concentration; multiovulate ovaries; leaf features; within-crop variation
