Summary
The interaction between the clonal dicotyledonous herb Trientalis europaea and the systemic smut fungus Urocystis trientalis was investigated. By marking individual plants in the field and transplanting plants to the greenhouse, disease transmission and the effect of disease on survival and fecundity of plants were estimated. Field data showed that 50% of the diseased and none of the healthy plants died during summer. Surviving diseased plants produced significantly fewer winter buds than healthy plants (means ±S.E. 1.12±0.05 and 1.88±0.07, respectively). Seed capsule production was low overall and did not differ between diseased and healthy plants. Disease was not seed-transmitted and transmission from infected mother plants to daughter ramets was not total (means 33% and 46%, in two experiments). Disease transmission was also influenced by light conditions.
