Abstract: | The prevalence of arbuscular mycorrhizas and nonsymbiotic modifications of absorbing organs (dauciform roots) has been studied in species of the genus Carex with competitive (C) and stress-tolerant (S) types of Grime-Ramenskii’s ecological strategies. The groups of C- and S-strategists do not differ in the ability to form mycorrhizas. Dauciform roots are more frequent in S-strategists, which accounts for a higher diversity of means for soil nutrient uptake in this group, compared to S-strategists. |
