4: Effect
of increasing temperature on physical and chemical properties of strawberry
fruit.
Temperature |
Reported
features |
Reference |
15 °C and 19 °C |
Decreased fruit size by 29% of FW and 33% of DW at 19 °C compared. to 15 °C due to lower dry matter
accumulation attributed to increased photorespiration and higher fruit
transpiration. |
Miura, et al. [46] |
Day/night: 18/12, 25/12, 25/22, and 30/22 (°C) |
Greater pigment intensity resulted in darker and
redder fruit due to increased anthocyanin content; Chroma color values
increased by 39%. Decreased fruit quality. Soluble solids content
(SSC) decreased by 36%, titratable acidity (TA) by 14%, SS/TA ratio by 25%,
and AA by 41%. 18/12 °C was the best temperature for
fruit growth with higher fructose (~390 mg/DW of fruit), glucose (~350 mg/DW
of fruit), and total carbohydrates (~770 mg/DW of fruit). Reduced fruit quality with smaller and
irregularly shaped fruits. Decreased organic acid content by 18% (mainly
citric acid) and ellagic acid by 15%. |
Wang and Camp [45] |
Day/night: 18/12, 25/12, 25/22, and 30/22 (°C) |
Significantly increased phenolic acid, flavonol, and anthocyanin content. Increased antioxidant capacity by nearly 54%. |
Wang and Zheng [50] |
25, 30, 35, 40 and 45 (°C) |
Largest
increase in peroxidase activity from 3 to 35 µmol/g min DW with gradual
increase in temperature (GHS). Smaller
increase in peroxidase activity in response to sudden temperature increase
(SHS) of 3 to 19 µmol/g min DW. Decreased
cellular protein by 51%
under GHS and by 67% under SHS. |
