Abstract
Counts of ovules per ovary enable latent infection with severe strains of swollen shoot virus to be detected in cacao trees.
The number of ovules is lower in flowers from infected trees than from healthy ones and is higher in trunk flowers than in those on the branches, the reverse of the difference found in healthy trees.
The distribution of ovules in trees infected with avirulent strains was not affected.
The number of ovules is lower in flowers from infected trees than from healthy ones and is higher in trunk flowers than in those on the branches, the reverse of the difference found in healthy trees.
The distribution of ovules in trees infected with avirulent strains was not affected.
Changes in ovule numbers were found only 1 month after inoculation with virulent virus and decreased progressively in subsequent months, more rapidly in flowers from branches than from the trunk.
