Observation Rhizomes had higher total soluble sugars than fine roots in A. odoratum.
Observation Rhizomes had higher total soluble sugars than fine roots in Equisetum. spp.
Observation Fine roots had higher total soluble sugars than rhizomes in R. acris.
Intervention effect Soil warming did not affect total soluble sugars in Equisetum.
Intervention effect Soil warming did not affect total soluble sugars in R. acris.
Intervention effect Soil warming increased total soluble sugars in A. odoratum fine roots and rhizomes under medium-term warming.
Intervention effect Soil warming increased total soluble sugars in A. odoratum fine roots under long-term warming.
Intervention effect Medium-term warming did not affect community fine-root soluble sugar concentration.
