Influence of the host on three sub‐Arctic annual facultative root hemiparasites
SUMMARY Growth, mineral accumulation and above‐ground dry‐matter partitioning were measured in three sub‐Arctic annual facultative root hemiparasites, Rhinanthus minor L., Euphrasia frigida L. and Melampyrum sylvaticum L., growing either unattached or attached to a host plant. Attached plants were a...
