Scientists introduce aesthetically advanced method for tagging, tracking roses

A new technology was introduced to imbed identification chips in rose canes. Researchers designed and tested a method for imbedding rose plants with radiofrequency identification microchips, then tracked the tagged plants using a database. The findings suggest that rose plants can be safely tagged with a microchip as early as the nursery phase without negative effects on plant appearance. The technology supports a variety of educational and research applications.

New pentrometer provides accurate crispness data for apple breeding programs

To measure the crispness of apples without relying on human test panels, researchers used a computerized penetrometer to assess firmness and texture of apple varieties and compared the results with sensory data from an expert panel. The scientists found a significant correlation between the penetrometer crispness value and the sensory crispness value and concluded that data from the test instrument was more useful than data from either a standard penetrometer or acoustic resonance test alone.

Effectiveness of commercial hydrators, holding solutions established for 121 cultivars

A multiyear study identified patterns of postharvest responses to commercial hydrator and holding floral preservatives among 121 cultivars of specialty cut flowers. Cut stems were pretreated with either a commercial hydrating solution or deionized water, then placed in either a holding solution or deionized water. Particular combinations of preservatives and hydrating treatments were found to either increase or decrease vase life of the flowers. The study contains valuable information for flower growers, retailers, and consumers.

Virus-tested seeds proven to increase yields

A survey was conducted to examine the performance and quality of a sweetpotato virus-tested foundation seed after it had been integrated into commercial operations in Louisiana. Results from the study suggest that producers are realizing yield benefits by incorporating virus-tested foundation seed into their production schemes, but further benefits could be attained if ways to reduce re-infection with viruses can be identified.
