Abstract
In gnotobiotic (monoxenic) experiments, the damage to sugar beet seedlings inoculated with 1,000 and 10,000 Heterodera schachtii larvae varied directly with numbers of nematodes added, and inversely with age of seedlings at the time of inoculation. The effects produced were, 1) delayed and reduced seedling emergence, 2) stunting, 3) necrosis, and 4) infection of hypocotyls of pre-emergent seedlings. In hypocotyls and cotyledons typical giant cell formation and larval development to females was not observed, however. Symptoms in pre-emergent and young, post-emergent seedlings sometimes resembled those produced by other kinds of root and hypocotyl-infecting pathogens.
