Within 3 weeks after transplanting
challenged pepper and melon seedlings to
the field, the protective effect of the preinoculation was visible on the foliage. This
effect is clearly seen in the size of the
plants in Figure 2D. Both CMV-D and
CMV-16 caused severe infection in pepper
with a disease intensity of 69 to 79%
(Table 1) and disease incidence of 100%
(Fig. 1). CMV-16 caused severe infection
in melon with a disease intensity of 79 to
87% (Table 2) and disease incidence of
100% (Fig. 1). Yield results shown in Tables 1 and 2 compare fruit yields of protected (vaccinated) and unprotected melon
and pepper plants during the course of this
study. With the yield from the healthy
plants taken as 100%, the yield for protected, protected and challenged, and
challenged plants was calculated.
