“…The ORAC values observed in control fruits were higher than those reported by Ehlenfeldt and Prior (2001) for Brigitta (17.7 µmol TE g -1 FW) and Legacy (13.5 µmol TE g -1 FW), which were similar to those reached in fruits from plants treated with 800 mg L -1 . This result was consistent with that reported by Ribera et al (2010), indicating that highbush blueberry fruits grown in southern Chile have exceptionally higher antioxidant activity in comparison to those cultivated in the Northern Hemisphere. The DPPH methodology used to determine antioxidant activity indicated a C×B (P≤ 0.05; Table 2), which increases the activity in Legacy fruits treated with 200 and 400 mg L -1 compared to the control (P≤0.05; Figure 4).…”

THE EFFECT OF FOLIAR BORON SPRAYING ON THE FRUIT FEATURES OF BRIGITTA AND LEGACY HIGHBUSH BLUEBERRY (Vaccinium corymbosum) CULTIVARS

is associated with reproductive and antioxidant metabolism in plants, and in southern Chile, the deficiency of this micronutrient is ameliorated through foliar applications that are a part of agricultural management, thus ensuring the productivity of crops including highbush blueberry (Vaccinium corymbosum L.). However, the appropriate B dosage for this species is unknown, so the aim of this study was to evaluate foliar B application on fruit quality in highbush blueberry in southern Chile. During the 2014-2015 season, Brigitta and Legacy cultivars were sprayed with B at rates of 0 (control), 200, 400 and 800 mg L -1 three times (10% bloom, full bloom, and fruit set), and fruit set (%), firmness (g mm -2), soluble solids (°Brix), weight (g) and size (mm) of the fruits were determined. In addition, antioxidant activity was measured by ORAC (oxygen radical absorbance capacity) and DPPH (2,2-diphenyl-1-picrylhydrazyl). The results showed that a low rate of B (200 mg L -1 ) increased the fruit set and soluble solids in Brigitta, whereas Legacy required higher B concentrations (400 and 800 mg L -1 ). In both cultivars, firmness, fresh fruit weight, dry matter (%) and antioxidant activity increased under the 200 and 400 mg B L -1 treatments, whereas this last parameter was reduced under a high B concentration. A low B rate showed to be more effective at improving fruit quality in Brigitta, while Legacy required higher B application rates. Future research should be performed over several seasons and different cultivars to confirm these results.

“…In this study, the effects of different short-term N treatments on the chemical, physiological and biochemical characteristics of highbush blueberry were evaluated. It is widely reported that leaves and fruits of blueberry exhibit a particularly high content of phenolic compounds (Ribera et al, 2010), which could be affected by the short-term N supply as previously found for other plants, such as Arabidopsis and chamomile (Kováčik et al, 2007;Olsen et al, 2008).…”

“…Since 1985, the highbush blueberry (Vaccinium corymbosum L.) has become an important crop cultivated in Chile (Lyrene and Muñoz, 1997;Ribera et al, 2010). Nonetheless, information concerning the physiology of this crop beyond its beneficial effects is lacking.…”

Photosynthetic and Antioxidant Performance Are Differentially Affected by Short-Term Nitrogen Supply in Highbush Blueberry Cultivars at the Short-Term

E. Yañez-Mansilla, P. Cartes, M. Reyes-Díaz, A. Ribera-Fonseca, and M. Alberdi. 2014. Photosynthetic and antioxidant performance are differentially affected by short-term nitrogen supply in highbush blueberry cultivars. Cien. Inv. Agr. 41(1): 61-70. Nitrogen (N) is an essential nutrient for photosynthesis and may influence phenolic compound synthesis in higher plants. The effect of different amounts of N (0 to 38 mM) provided on a short-term (4 d) basis on the photosynthetic and antioxidant performance of highbush blueberry cultivars (Legacy and Bluegold) grown in a nutrient solution was studied. In both cultivars, the N concentration of leaves slightly increased in response to the N supply, with Bluegold frequently showing higher N concentrations than Legacy. Photosynthesis was reduced in Bluegold at the highest N dose, whereas in Legacy, a decrease of CO 2 assimilation occurred under N starvation. This decrease in photosynthesis was accompanied by enhanced lipid peroxidation but only in Bluegold. In both cultivars superoxide dismutase (SOD) was activated with an increasing N supply. Legacy also showed increased SOD activity to counteract oxidative stress at higher N levels. Radical scavenging activity was not affected by the N supply. However, the total phenols and anthocyanins steadily declined in the leaves of Legacy, and flavonoids were significantly increased in the roots of both cultivars with increasing N treatments. Thus, our findings indicate that blueberry cultivars exhibit differential sensitivity to short-term N stress, and SOD appears to be more involved than phenolic compounds in the amelioration of N-induced oxidative stress. Further studies are required to confirm the sensitivity to either N starvation in Legacy or N excess in Bluegold under long-term conditions.

in Szczecin and at a certified production farm specializing in the cultivation of highbush blueberry located in Szczecin. The effect of cultivation conditions-organic plantation in organic peat substrate (pH 3.46) and conventional plantation in mineral substrate (pH 5.32)-on the berry quality of four highbush blueberry cultivars (firmness, size, chemical composition including content of organic compounds and polyphenols) was examined. Blueberry bushes were planted at a spacing of 2.3 × 1.2 m. Bushes were planted on organic and conventional plantations, and the substrates differed in terms of mineral content. Specific environmental conditions and soil conditions (optimum pH of the substrate) resulted in larger berries on the organic plantations, and the total yield contained big berries (diameter, >12 mm; mean, 83.4%) with lower polyphenol content (287 mg 100 g -1 ). The berries of the Elliott cultivar, regardless of how the crops were grown, were the largest, characterized by the lowest content of SS (15.3%) and the highest acidity (0.98 g 100 g -1 ). They were also the most likely to shed. The Duke cultivar was most susceptible to mechanical damage (101 G mm) and was characterized by the lowest berry firmness (162 and 363 G mm) and polyphenol content (organic, 185 mg; conventional, 228 mg 100 g -1 ).
