Tomatoes of different types and cultivars are grown in different parts of the world. Accordingly, the phenological, pomological and biochemical characteristics of these types and cultivars may differ from each other, and therefore their ripening behaviours may also differ. The present study aimed to determine the respiration rate and ethylene production of twelve commonly grown cultivars in Turkey at harvest and during the ripening stage. The fruits were harvested at the mature green stage and categorized according to their size as small, medium and large-fruited cultivars.
At harvest time, the highest respiration rate was determined from 'Moda' (small-fruited) cultivar and the lowest was from 'Elips' (medium-fruited). The highest ethylene production was determined from 'Sarikiz' (small-fruited) and the lowest was from 'Alberty' (large-fruited). All tomato cultivars examined in the study showed climacteric respiration behavior during the ripening, and it was determined that small-fruited types had a higher respiration rate and ethylene production compared to medium and large-fruited ones. 'Sarikiz' (small-fruited) had the highest climacteric peak and 'Gulpembe' (large-fruited) had the lowest. Moreover, it was determined that the respiration rate of small-fruited cultivars were 5.01-fold higher compared to other cultivars and this type of cultivars produced 4.19-fold higher ethylene compared to big-fruited cultivars at harvest. Medium-fruited tomatoes had 1.90-fold higher respiration rate and 1.64-fold ethylene production compared to big-fruited tomatoes.
It was determined that fruit size and respiration rate were related independently of the cultivars, although there was no relationship between fruit size and ethylene production. © 2022 Society of Chemical Industry.
不同类型和品种的番茄在世界不同地区种植。因此，这些类型和品种的物候学、园艺学和生物化学特性可能彼此不同，因此它们的成熟行为也可能不同。本研究旨在确定 12 个在土耳其广泛种植的品种在收获时和成熟过程中的呼吸速率和乙烯生成量。果实成熟至绿熟期，按果实大小分为小果型、中果型和大果型品种。
在收获时，呼吸速率最高的是‘Moda’（小果型）品种，最低的是‘Elips’（中果型）品种。乙烯生成量最高的是‘Sarikiz’（小果型）品种，最低的是‘Alberty’（大果型）品种。研究中检查的所有番茄品种在成熟过程中均表现出跃变型呼吸行为，并且小果型品种的呼吸速率和乙烯生成量均高于中果型和大果型品种。‘Sarikiz’（小果型）的跃变峰最高，‘Gulpembe’（大果型）的最低。此外，小果型品种的呼吸速率比其他品种高 5.01 倍，收获时小果型品种比大果型品种产生的乙烯高 4.19 倍。中果型番茄的呼吸速率比大果型番茄高 1.90 倍，乙烯生成量高 1.64 倍。
尽管果实大小与乙烯生成量之间没有关系，但果实大小与呼吸速率独立相关。 © 2022 化学工业协会。
