“…Previous work has demonstrated that the photosynthetic capacity of blueberry plants is significantly influenced by a range of external and internal factors, such as source-sink relationships, 19,39 temperature, 7 and light intensity and spectrum. 6,18,40 Experiments were therefore conducted to determine whether growth over reflective mulch altered leaf photosynthesis.…”

“…4 However, the observation that yields are high and stable in North America but more variable elsewhere 5 suggests that cultivars bred in North America may not be adapted to local environmental conditions in other growing territories. For example, high UV in South American growing environments has been shown to impair photosynthesis; 6 high temperatures, such as those encountered in southern Chinese growing regions, inhibit photosynthesis and biomass accumulation; 7 while variable seasonal light availability contributes to seasonal yield variation in northern European climates. 5 In the long term, the solution to such issues is likely to revolve around breeding locally adapted cultivars, as has been achieved with the development of southern highbush cultivars that require lower winter chill than their northern highbush counterparts.…”

BACKGROUND: In maritime growing environments, blueberry yield often exhibits excessive season-to-season variation, associated with poorly adapted photosynthetic responses to low light conditions. It is therefore necessary to develop methods that stabilise yield while maintaining or improving fruit quality. Here, we placed reflective mulch alongside plants at the early green fruit stage, to test the hypothesis that increasing the available seasonal light integral could enhance blueberry yield. We further determined several quality characteristics to ensure fruit marketability.RESULTS: Placement of mulch alongside plants reflected up to five times more light compared with bare ground, enhancing the amount of light reaching the canopy. This led to an adaptive increase of light saturated maximal photosynthetic rate of mulchtreated plants, resulting in a twofold increase in yield compared with control plants. Analysis of fruit quality characteristics showed that total soluble solids, sugars and organic acids were similar between treatments. Likewise, antioxidant capacity, total anthocyanin content and the content of individual anthocyanins did not change in response to reflective mulch treatment. CONCLUSIONS:The use of reflective mulch should be explored by industry as a cost-effective method for enhancing blueberry yield while maintaining fruit quality in maritime environments.

“…Heat stress may be somewhat mitigated if transpiration-mediated cooling can be maintained, for example, rice can remain productive in air temperatures of 40°C if humidity remains low (Jagadish et al, 2014). In Blueberry, the thermal tolerant cultivars could improve their heat dispersing efficiency through regulating stomatal traits (Hao et al, 2019). In present study, the E of all cultivars was significantly increased under high temperature.…”

Photosynthesis is highly sensitive to high temperature stress, and with the rising global temperature, it is meaningful to investigate the response of photosynthesis to growth temperature and its relationship with leaf anatomy plasticity. We planted 21 cultivars including eight indica cultivars, eight japonica cultivars, and five javanica cultivars in pot experiments under high growth temperature (HT, 38/28°C, day/night) and control treatment (CK, 30/28°C, day/night). Photosynthetic rate (A), stomatal conductance (g s ), transpiration rate (E), stomatal density (SD), vein density (VD), minor vein area (SVA), and major vein area (LVA) were measured after 30 treatment days. Results showed HT significantly increased A, g s , and E, while significantly decreased SD and LVA. There was no significant difference in A among the three subspecies both under CK and HT, while the javanica subspecies had higher g s , E, SVA, and LVA under HT, and the indica cultivars had higher VD and SD both under CK and HT. The javanica subspecies had higher relative value (HT/CK) of A, g s , and E, while difference was not observed in the relative value of SD, VD, and LVA among the three subspecies. The relative value of A was positively related to that of g s , while the latter was not correlated with the relative value of SD, VD, SVA, and LVA. Overall, the results suggested the increase of A and g s at HT was not attributed to leaf anatomy plasticity in respect of stomata and vein under HT. HIGHLIGHTS 1. High growth temperature (HT) significantly affected rice leaf photosynthetic rate (A), stomatal conductance (g s ), transpiration rate (E), stomatal density (SD), and major vein area (LVA). 2. The javanica subspecies had higher g s , E, and LVA under HT, and possessed higher heat resistance than indica and japonica subspecies. 3. Across different cultivars, the response of A and g s to HT were not related to leaf anatomy plasticity such as stomatal and vein anatomy.

“…Culture conditions of V. corymbosum have shown a clear influence on its composition, including phenolic compounds. In relation to temperature, different authors have shown that temperatures between 20 and 30 • C ensure the highest phenolic concentration in blueberries, while higher temperatures have adverse impacts on their growth and composition [14][15][16]. In addition, the use of ammonium compounds (RNH 4 + ) improved the plant performance and the phenolic compounds composition.…”

In recent years, consumers’ preference for fruits such as blueberry has increased noticeably. This fact is probably related to their bioactive components such as anthocyanins, phenolic compounds, vitamins, minerals, and tannins that have been found in blueberries by the latest research studies. Both total anthocyanins (TA) and total phenolic compounds (TPC) are known for their multiple beneficial effects on our health, due to their anti-inflammatory, anti-oxidant, and anti-cancer properties. This is the reason why the development of new methodologies for the quality control analysis of raw materials or derived products from blueberry has a great relevance. Two ultrasound-assisted extraction methods (UAE) have been optimized for the quantification of TA and TPC in blueberry samples. The six variables to be optimized were: solvent composition, temperature, amplitude, cycle, extraction solvent pH, and sample/solvent ratio using response surface methodology. The optimized methods have proven to be suitable for the extraction of the TPC and TA with good precision (repeatability and intermediate precision) (coefficient of variation (CV) < 5%) and potentially for application in commercial samples. This fact, together with the multiple advantages of UAE, makes these methods a good alternative to be used in quality control analysis by both industries and laboratories.
