Abstract

Relative weights of 97 days-old oat plants in pots inoculated with a range of densities of Heterodera avenae eggs and juveniles at sowing as well as once or twice on later dates, were the products of the relative weights that would have been obtained after single inoculations onthe same dates. Plants in pots inoculated with large nematode densities at sowing were an exception. Their physiological age at the time ofthe later inoculations was reduced (retardation of development), which made them more sensitive to weight reduction by the nematodes than uninoculated plants of the same actual age. The plants were less tolerant to nematodes already present at sowing than to those introduced into the soil later but which attacked the same roots at the same time. This creates a theoretical paradox.
