The obligate parasites can only germinate in the vicinity of host roots. Their minuscule seeds contain a reduced embryo that in some genera lacks cotyledons. The fine structure of the seed, its accumulation of nutritional reserves and the role of the labyrinthine wall in the endothelium are amongst the various seed aspects that are described and discussed in this chapter. It also discusses the perception site for host-derived germination stimulants and the pathway of nutrients to the embryo during germination and describes the structure of the seedling.
