Fig. 5. Rosa roxburghii in two calcium conditions. Left: R. roxburghii grows on acidic low calcium yellow soil with pH 5.02 and exchangeable calcium content of 432 mg·kg-1, there were more acidic indicator ferns around the plant. Right: R. roxburghii grows in alkaline calcareous soil with pH 8.24 and exchangeable calcium content up to 6 631 mg·kg-1.
