Summary
Quantitative and qualitative differences are reported in the composition of the root exudates of six plants from four families, barley, wheat, cucumber, turnip cabbage, tomato, and red pepper, in the initial stages of growth and for the last two species, also at the fruiting stage. It is concluded that the less the plants are related phylogenetically, the greater is the difference in the composition of the exudates. These results are discussed in relation to certain aspects of the rhizosphere effect.
