Abstract
The Ca2+ content of Heterodera schachtii egg-shells was investigated by X-ray microanalysis. The egg-shells contained Ca2+, most of which was probably present in the inner lipoprotein membrane. Results from experiments with artificial hatching and non-hatching agents suggested that hatching agents, by binding to or replacing membrane-bound cations, induced structural change in the membrane and hence altered egg-shell permeability to solutes. The results are discussed in relation to previous work on the hatching mechanism of Globodera rostochiensis.
