Abstract
In a previous communication (Giebel and Stobiecka, 1974) it is suggested that a decrease in the ratio of protein proline to hydroxyproline in potato roots after their infection with Heterodera rostochiensis Woll. may suppress cell hypertrophy and, in this way enhance the resistant response to this nematode. This paper describes how we tested this hypothesis by introducing into nematode infected potato plants solutions of hydroxyproline, proline and a mixture of the two as well as 2,2'-dipyridyl (an inhibitor of protein-bound hydroxyproline formation) and benzimidazole (a promoter of hydroxyproline synthesis).
