Blossom-end rot (BER) is a physiological disorder that can affect 100% of the fruit crop depending on the genotype. Tomato varieties with elongated fruit usually have a greater susceptibility to BER than other varieties. To evaluate and identify the possible physiological and morphological characteristics related to the onset of BER development, four varieties of long-shape tomato fruit with different susceptibility to BER: ?San Marzano,? ?Banana Legs,? ?Roma,? and ?Mini-Roma? were examined. Our results show that ?San Marzano? and ?Banana Legs? (elongated fruit) had a higher incidence of BER and lower Ca2+ concentration in the distal fruit tissue. ?San Marzano? (the most elongated fruit) presented higher electrolyte leakage in the distal fruit tissue. By comparison, ?Roma? and ?Mini-Roma? (less elongated fruit) were less susceptible to BER and had a higher ratio for proximal/distal fruit Ca2+ and a lower distal cell-wall bound content of Ca2+. Additionally, xylem functionality (vessels transporting water and solutes) in the distal fruit tissue was also higher in these more-tolerant varieties. These results support the theory that total fruit content of Ca2+ is not the only factor determining fruit susceptibility to BER, but rather a balance between physiological and morphological factors that influence Ca2+ transport and allocation in the fruit. |
