Blossom-end rot in relation to morphological parameters and calcium content in fruits of four pepper varieties (Capsicum annuum L.). The objective of this study is to identify, in the case of four pepper cultivars: ' J27 ', ' Marconi ', ' Beldi ' and ' Jerid ', a relation between vegetative growth rate, fruit weight and its calcium content with blossom-end rot induction. The results show that the more sensitive cultivars to blossom-end rot are ' Marconi ' and ' J27 ' cultivars, those having a larger final size and faster growth speed of the fruits and a higher rate of transpiration in comparison with ' Jerid ' cultivar, which is characterized by its small fruits. On the other hand, the calcium contents of their fruit, especially in the apical part, is weaker than the ' Jerid ' cultivar’s one.
