Abstract. Interactions between parasitic angiosperms and their hosts occur at the level of seed germination, haustorial development resource transfer. Chemicals released from host function as cues for recognition, trigger germination well initiation. Transpiration is a key process regulating solute transfer to parasite, some parasitie plants have unusual stomatal characteristics. Although apoplastic, haustorium appears play role in composition. Host responses infection are reviewed, it concluded that competition water solutes unlikely major determining reductions productivity: metabolic incompatability suggested be cause this.
