The objective of this study was to evaluate and identify morphological and physiological characteristics related to the susceptibility of tomato varieties to BER. The varieties studied were ‘Amalia’, ‘IPA-6’, ‘M-82’, ‘Mara’, and ‘Nagcarlan’, presenting different fruit formats. Physiological parameters that negatively correlated with BER were plant water potential, leaf area, plant dry mass, relationship between proximal/distal Ca2+, K+ content in the proximal and distal portions of the fruit, and proximal Ca2+ content. Physiological parameters that positively correlated with BER were number of trichomes in the abaxial and adaxial leaf portions, leaf stomatal conductance, distal Ca2+ content bound to the cell wall, leaf transpiration, and fruit length. Our results showed that ‘Mara’ and ‘Nagcarlan’, ‘Amalia’ and ‘IPA-6’, and ‘M-82’ presented low, medium, and high susceptibility to BER, respectively. We also found that total fruit Ca2+ concentration, particularly in the distal fruit tissue, was not the only factor responsible for the development of BER; rather, the balance between factors that increase and decrease the susceptibility of each variety affected development of this disorder. 2020 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303062597045 https://www.redalyc.org/journal/3030/303062597045/ https://www.redalyc.org/journal/3030/303062597045/html/ https://www.redalyc.org/journal/3030/303062597045/303062597045.epub https://www.redalyc.org/journal/3030/303062597045/movil 10.4025/actasciagron.v42i1.42487 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
