seed count, fruit quality and storage properties in four apple cultivars

J. Blažek and I. Hlušičková
Furthermore, seed count in ‘Nabella’ is also positively correlated with bitter
pit. Affected fruits are susceptible to internal breakdown (Fig. 5). Bitter pit seems
to be strongly correlated with calcium content (Brookfield et al., 1996).
In ‘Resista’, apples with a high seed count were less susceptible to
superficial scalding (Fig. 6).

In the storage trial, fruits with a high seed count were less susceptible to
rotting caused by pathogenic fungi such as Monilia, Gloeosporum and
Botrytis (Fig. 6 and 7). However, sometimes this relationship broke down
