A Refinement of Gemmell's single cyst technique

Abstract

Whilst studying the hatching of larvae from cysts of Heterodera rostochiensis in different samples of potato and tomato root excretions, in the hope of ultimately developing a technique for the standardisation of root excretion, the author felt that it might be worth while to publish details of a refinement of Gemmell's (1940) single cyst technique.
