“…An increase in the proportion of sucrose in melon fruit is associated with a decline in acid invertase (AI) activity (Chrost and Schmitz, 1997) and an elevation in sucrose phosphate synthase (SPS) activity (Gao et al, 1999;Hubbard and Pharr, 1990;Hubbard et al, 1989;Lingle and Dunlap, 1987;Yamaki, 2010). These results suggest that reduced and increased AI and SPS activities, respectively, are critical for the attainment of cell maturity in melon fruit.…”

To determine the relationship between cell size, acid invertase (AI) and sucrose phosphate synthase (SPS) activities, and sucrose accumulation in melon (Cucumis melo L.), fruit were treated with succinamic acid 2,2-dimethylhydrazide (SADH) at various developmental stages during spring and summer. Fruit and cell growth was suppressed by SADH treatment during early, but not middle, development. Higher AI activity and lower SPS activity and sucrose content were observed in fruit with smaller cells exposed to early SADH treatment, compared to fruit with larger cells exposed to late SADH treatment. These results suggest that the low sucrose content in fruit treated with SADH during early fruit development is due to the lower SPS activity of smaller cells resulting from SADH exposure.

“…Only slight differences were observed between the two maturity stages in TA and color index at harvest. Previous studies in kiwifruit and other fruit demonstrated that harvesting maturity has a significant effect on post-harvest quality characteristics associated with metabolic conversion on and off tree (Hopkirk et al, 1989;Jason et al, 2002;Yamaki, 2010), thus influencing fruit storage life and edible quality characteristics (Crisosto et al, 1984). Recent studies in 'Hayward' have also demonstrated that late harvested fruit have a shorter storage life than early harvested fruit (Tavarini et al, 2009).…”

The effects of modified atmosphere (MA) storage and application of 1-methylcyclopropene (1-MCP) at harvest on the storability and quality of 'Sanuki Gold' kiwifruit harvested at two different maturity stages were investigated. MA storage in both fruit harvested early at 136 days after pollination (DAP) or late at 154 DAP delayed flesh softening, increase in soluble solid concentrations (SSC), decrease in titratable acids (TA), and reduction in fruit flesh color index compared to air stored fruit, suggesting that MA storage is effective in prolonging 'Sanuki Gold' kiwifruit storage life. Further, MA stored fruit did not attain full ripening flesh firmness and SSC thresholds even after 4 months of storage under MA conditions, suggesting that early harvested 'Sanuki Gold' kiwifruit can be stored for 4 months in MA. Fruit from both harvesting maturity stages stored under air conditions achieved maximum SSC (18%) values during storage, suggesting that two weeks early harvesting did not compromise edible quality characteristics. Only late harvested fruit treated with 1-MCP and stored in MA showed slight inhibitory effect specific to fruit softening during the first and second month of storage, suggesting that 1-MCP may have some limited ripening inhibitory effect during storage of 'Sanuki Gold' kiwifruit.

“…Scientists support both theories and many studies have been conducted to validate them. Yamaki (2010) discusses the influence of sink strength during the various steps between photoassimilate synthesis in leaves and its accumulation in fruit. In addition, sugars improve fruit quality because they are the primary substrate of various fruit components.…”

The occurrence of the abscission signal in young developing fruits on apple trees (Malus domestica) was studied. Apple has a natural system of fruitlet shedding, so called June drop. Although physiological fruit drop is unable to guarantee production of marketable apples and avoid alternate bearing, knowledge of this is a key background for successful fruit thinning. A study was carried out on apple trees cv. 'Golden Delicious' during June drop. On three dates (beginning, middle and end of June drop), the daily dynamics of HPLC detected individual sugar and spectrophotometrically detected total phenolic content was investigated in central (K) and lateral (L) fruitlets. The results of daily dynamics showed the highest sugar contents at 2 p.m. On the final sampling date, on 2 nd July 2015, we observed a significant difference between sugar contents at 2 p.m. and the morning and afternoon measurements. Contents of sugars in K and L fruitlets were not significantly different. Total phenolic content at the beginning of June drop was higher than at the end. There was no statistically significant difference between K and L in an individual time period, while there were statistically significant differences in total phenolic content among the sampling dates. Although sugar and phenolic content in K and L fruitlets were rarely statistically different, their contents changed during June drop. In general, sugar contents increased and phenolic content decreased during the process, while the daily dynamic depended on weather conditions.
