Berries grown in hot, dry climate have higher antioxidant capacity than supermarket varieties

Six cultivars of primocane raspberries were grown in a hot, dry climate and compared for their antioxidant and phenolic content. 'Autumn Bliss' had the highest oxygen radical absorbance capacity (ORAC) and phenolic content over time, whereas 'Caroline' had the lowest ORAC and phenolic content when fresh. Other analyses showed that antioxidant capacity and total phenolic content of the ripe berries varied between cultivars and showed no significant change after common consumer storage methods.

Higher saline levels in irrigation water don’t compromise plant quality

A study determined how moderate salinities imposed by NaCl affect calla lily growth, including flower production and developmental timing such as emergence and flowering. Calla lilies exposed to 25-mM NaCl treatment with an irrigation water electrical conductivity (EC) approximately twice the recommended amount had no significant reduction in biomass or flower number compared with the control, showing that irrigation water with a higher EC can be used without sacrificing calla lily quality.

Study finds cherry tomatoes more robust when grown under blue-hued LEDs

Scientists evaluated cherry tomato seedlings grown under dysprosium lamps and six light-emitting diode light treatments. Compared to the control, net leaf photosynthesis was increased significantly under blue, red and blue, and red, blue, green light and reduced under red, orange, and green treatments. Leaf thickness and length of palisade tissue cells significantly increased under blue, red and blue, and red, blue, green lights. Results suggested blue light is essential for growth of cherry tomato plants.

Drip irrigation outshines microsprays, sprinklers in water use efficiency

A study of northern highbush blueberry determined the effects of three irrigation methods on growth and water requirements of uncropped plants during the first two years after planting. Drip irrigation at 100% evapotranspiration produced the most growth, requiring at least 42% less water than needed (for maximum growth) with microsprays and 56% less water than needed with sprinklers. Results proved that irrigation water use efficiency was significantly higher with drip than with the other methods.
