American Potato Journal Aims and scope Submit manuscript

Summary

  1. 1.

    Local ringlike-necrotic lesions (Figures 1 and 3), which appear on the inoculated leaves ofNicandra physaloides, are shown to be characteristic and differential symptoms of the strain of potato-virus Y, described by Silbershmidt, Rostom and Mattos Ulson (8). The same strain also induces systemic symptoms inNicandra physaloides (Figure 2).

  2. 2.

    In the discussion the several differential hosts of strains of the potato-Y-virus, described in the literature, are reviewed and the special character of the symptoms induced by our strain of potato-virus-Y on the inoculated leaves ofNicandra physaloides are pointed out. These symptoms are local without being primary.
