Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Primocane fruiting blackberry production in Arkansas is limited by heat during the flowering and early fruiting season. Shade could be used to delay flowering and fruiting to more favorable growth period. This study was designed to test three levels of shade (0% [control], 30% and 50% shading) applied at three times during the growing season that examined the growth, development, physiology of flowering, and fruiting of ‘Prime-Ark® 45’ blackberries. The seven treatments were as follows: 1) an untreated control (CK), 2) early shade 30% (ES30), mid shade 30% (MS30), 4) late shade 30% (LS30), 5) early shade 50% (ES50), 6) …

Evaluation Of Harvest Time/Temperature And Storage Temperature On Postharvest Incidence Of Red Drupelet Reversion Development And Firmness Of Blackberry (Rubus L. Subgenus Rubus Watson), Jack E. Mccoy, John R. Clarke, Alejandra A. Salgado, Andrew Jecmen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Since 1964, the University of Arkansas blackberry breeding program has worked to improve fruit quality and shipping capabilities. A major limitation in blackberry fruit is postharvest handling potential for the shipping market. Maintaining fruit firmness in storage is crucial. Red drupelet reversion (or simply reversion) is also an important postharvest disorder in which drupelets change from black to red during storage. It is hypothesized that reversion is increased when fruit is picked at hot temperatures and exposed to a rapid change of temperature. These studies evaluated harvest time/temperature, as well as storage temperature, on berry firmness and the incidence of …

Polyphenol Content And Differential Expression Of Flavonoid Biosynthetic Pathway Genes Of Fragaria Spp. With White Fruit, Sutapa Roy

Theses and Dissertations--Plant and Soil Sciences

Strawberries are a rich source of polyphenols which contribute to berry color and plant disease resistance, and have been shown to lower the risk of many chronic when consumed. While a considerable body of work exists on the polyphenolic composition of commercial strawberry (Fragaria x ananassa Duch.), less information is available concerning polyphenols in Fragaria vesca, or Alpine strawberry, considered a model system for the Rosaceae family of crop species. The study of natural and genetically-engineered F. vesca mutants with white fruit can provide unique insight into regulation of metabolic flux through the complex branched phenylpropanoid/flavonoid biosynthetic pathway. …

Review Of A Garden Of Marvels: How We Discovered That Flowers Have Sex, Leaves Eat Air, And Other Secrets Of Plants, By Ruth Kassinger, Robert F. Diffendal Jr.

Robert F. Diffendal, Jr., Publications

Until I read Kassinger’s book I clearly did not have the historical perspective necessary to appreciate the incredible lives of plants and how botanists have come to their present understandings of same. Kassinger, a gardener by avocation, cut out most of the jargon, defined terms that she does use, and wrote simple and compelling tales of the histories of discoveries about the various parts of plants and how those parts work together for the benefit of the plant and, ultimately, for our benefit.

[This] is a book that any gardener or other interested person with a modest background in plant …
