Seed Development and Germination

Unlike almost all other higher plants, the germination of root parasites depends on receipt of a chemical signal. They germinate only in response to specific chemicals present in the rhizosphere of host plants. In these parasitic flowering plants, which are totally dependent on a specific association with a host that provides them with nutrients and water, the recognition system ensures that germination starts only when suitable host roots are available in the immediate vicinity. This unique system is known for all Or-obanchaceae, four genera within the family Scrophulariaceae (Lathraea, Tozzia, Striga, and Alectra), and for most Rafflesiaceae, Balanophoraceae, Hydnoraceae, and Lennoaceae (Chang and Lynn, 1986; Press et aL, 1990). © 1995 by Marcel Dekker.
