Characterization of seediness attributes of blackberry genotypes

Fresh market blackberries can feel “seedy” when consumed. This “seediness” is associated with the presence of pyrenes which are comprised of a single seed enclosed in an endocarp. Small pyrene size

Evaluating Consumer Sensory and Composition Attributes of Arkansas-Grown Fresh-Market Blackberries

Blackberries are grown worldwide for commercial fresh markets. Three Arkansas-grown fresh-market blackberry genotypes (‘Natchez’, ‘Ouachita’, and A-2418) were evaluated for consumer sensory and compositional attributes at the University of Arkansas Food Science Department, Fayetteville. The compositional attributes of the blackberries were within an acceptable range for commercial markets (soluble solids=8.20-11.90%, pH=2.79-3.18, titratable acidity=1.09-1.32%). In terms of soluble solids to titratable acidity ratio, ‘Ouachita’ (10.92) had the highest ratio, followed by ‘Natchez’ (8.93) and A-2418 (6.25). A consumer sensory panel (n=80) evaluated fresh-market blackberry attributes using a 9-point hedonic scale for overall impression, overall flavor, sweetness, and sourness and a 5-point Just-about-Right (JAR) scale for sweetness and sourness. The participants also ranked the blackberries in order of overall liking from most to least liked. For overall impression, overall flavor, and sweetness, ‘Natchez’ scored higher than ‘Ouachita’ and A-2418, but the panelists did not detect differences in sourness. In terms of JAR for sweetness, 64% of consumers scored ‘Natchez’ JAR, followed by ‘Ouachita’ (39%) and A-2418 (34%). Whereas, 42% percent found A-2418 “Too Sour”, followed by ‘Ouachita (33%) and ‘Natchez’ (25%). In terms of ranking the blackberries, ‘Natchez’ was the most liked blackberry followed by ‘Ouachita’ and A-2418. When looking only at blackberries ranked first, 53% of consumers ranked ‘Natchez’ as their most liked berry, compared to A-2418 (26%) and ‘Ouachita’ (21%). The results from this research suggested that fresh-market blackberries with medium-level sweetness to sourness ratios were preferred though more consumers than expected preferred the blackberries with the more extreme ratios

The fractional integrated bi- parameter smooth transition autoregressive model

This paper introduces the fractionally integrated Bi-parameter smooth transition autoregressive model (FI-BSTAR model) as an extension of BSTAR model proposed by Siliverstovs (2005) and the fractionally integrated STAR model (FI-STAR model) proposed by van Dijk et al. (2002). Our FI-BSTAR model is able to simultaneously describe persistence and asymmetric smooth structural change in time series. An empirical application using monthly growth rates of the American producer price index is provided.Long Memory, Nonlinearity, Asymmetry, STAR models.

Grape Plant Named ‘Indulgence’

Description and specifications of a new and distinct cultivar of wine grapevine which originated from a hand-pollinated cross of ‘Seyval Blanc’ (female parent) and ‘Muscat Ottonel’ (male parent) made in 1988. The seedlings fruited in the summer of 1992 in a vineyard near Clarksville, Ark. and one was selected for its potential as a wine grape for utilization in the Mid-South. The original vine was tested as ‘Ark. 2359’. The new cultivar of grapevine is a white wine grape which is adapted to the Mid-South of the United States with good winter hardiness and distinct muscat flavor

Grape plant named `Opportunity`

Description and specifications of a new and distinct wine grape cultivar which originated from a hand-pollinated cross of `Cayuga White` (Vitis labrusca L. by V. vinifera L., developed by the New York State Agricultural Experiment Station, Geneva, N.Y.; female parent, non-patented) x A-1754 (non-patented, non-released breeding genotype; male parent). This new wine grape cultivar can be distinguished by its quality juice attributes for wine production with hardy and productive grapevines adapted to Arkansas and the Mid-South of the United States

Grape Plant Named ‘Dazzle’

Description and specifications of a new and distinct cultivar of grapevine which originated from a hand-pollinated cross of ‘Gewürztraminer’ (female parent) x ‘Melody’ (male parent) made in 1991. The seedlings fruited in the summer of 1992 in a vineyard near Clarksville, Ark. and one was selected for its potential as a wine grape for utilization in the Mid-South of the United States. The original vine was tested as ‘Ark. 2574’. The new cultivar of grapevine is intended for wine production and provides advancements in cold hardiness

Grape plant named `Enchantment`

Description and specifications of a new and distinct wine grape cultivar which originated from a hand-pollinated cross of Ark. 1628 (non-patented, non-released breeding genotype; female parent) x Ark. 1481 (non-patented, non-released breeding genotype; male parent). This new wine grape cultivar can be distinguished by its quality juice attributes for wine production with hardy and productive grapevines adapted Arkansas and the Mid-South of the United States

Doubling Down on Wicked Problems: Ocean ArtScience Collaborations for a Sustainable Future

The UN Decade of Ocean Science for Sustainable Development recognizes the current ocean sustainability crisis and calls for a transformation of ocean science. Many of the key challenges recognized by the UN Decade are examples of wicked problems: intractable and messy situations with high stakeholder divergence. Addressing wicked ocean sustainability problems requires adaptable, iterative, and participatory approaches that can embrace multiple ways of knowing. It also requires a re-imagining of our relationship with the Ocean from extraction and resulting environmental degradation, towards the building of a sense of connection and stewardship. We propose ArtScience as a means to this end by highlighting how transdisciplinary collaborations can help create sustainable ocean futures. We reflect on a recent ArtScience event emerging from Ocean Networks Canada’s Artist-in-Residence programme. By situating ArtScience in a broader context of inter- and transdisciplinary collaborations, we demonstrate how ArtScience collaborations can help transform ocean science by envisioning previously unimagined possibilities, and establishing and strengthening relationships with diverse stakeholders through long-term mission-driven or place-based inquiry. We conclude with a call to action to acknowledge the potential these collaborations hold for addressing the challenges of the UN Ocean Decade
