Histopathological and histochemical studies on grapevine roots damaged by Xiphinema index



Histopathological and histochemical studies on grapevine roots damaged by Xiphinema index



Revue de Nematologie, 12: 217-225



An histopathological and histochemical study was made of grapevine feeder roots infested by Xiphinema index. The first visible symptoms of nematode feeding, which appeared 6 to 8 hours after feeding began, were hypertrophy of cells and a drastic reduction in number of cell divisions. Continued feeding resulted in cessation of longitudinal root growth and swelling of the root tip. Multinucleate giant cells and mononucleate hypertrophied cells developed at feeding sites.
