10 pages, Biotechnology use in food production has been a polarizing topic that has encountered resistance from some consumers. The discovery of genome editing biotechnology, in which no foreign genetic material is introduced into the host organism while making accurate and efficient changes in genomes, has the potential to revolutionize food biotechnology in a more socially acceptable and less polarizing fashion. The success and adoption of gene-edited foods, however, ultimately depends on consumer acceptance. This study reports the results of a geographically disperse Chinese consumer acceptance study (n = 835) in which individuals evaluated rice and pork products that were bio-engineered to address two significant hazards that have recently garnered international attention: cadmium contamination in rice and African swine fever. We explore the role that food technology neophobia has on consumer acceptance and assess how information on the differences between transgenic and gene editing technologies affects consumer preferences. While averse to the use of biotechnology in food products, consumers were considerably more accepting of products that have undergone genome editing rather than transgenic modification. We find differential impacts of information provision on preferences between pork and rice products and on preferences for product provenance. Our analysis indicates that a reduction in consumers’ fear of novel food technologies can substantially increase consumer valuation and market acceptance of bioengineered food products and reinforces the need to consider attitudes in measuring acceptance of novel food products.
4 pages, via Online journal, Bougainvillea (Bougainvillea sp.) plant inflorescence number will vary in response to multiple cues such as changes in temperature, water, light intensity, pruning, and photoperiod. Previous research reports that the application of plant growth regulators (PGRs) to bougainvillea grown under varying photoperiods improved inflorescence number, probably as a result of changes in gibberellic acid (GA) levels. There are many bioactive plant GAs, but we chose to investigate differences in gibberellic acid 3 (GA3) levels and inflorescence number in response to the application of ethephon (2-cholorethylphosponic acid) or abscisic acid (ABA) to ‘Afterglow’ bougainvillea (Bougainvillea ×buttiana) grown under 14-hour photoperiod [long-day (LD)] conditions. Plants were 5 inches tall with seven visible lateral nodes and were grown in a greenhouse in 4-inch pots filled with 5-mm coarse aquarium zeolite. Ethephon was applied as a foliar spray at 0.05, 0.07, 0.10, 0.15, or 0.20 mg/plant. ABA was applied as a soil drench at 1, 1.5, 3, 6, 8, or 10 mg/plant. Endogenous levels of GA3 were measured 1 and 48 days after treatment to calculate the change in GA3 (∆GA3). A short day (SD) control of 8 hours was included to measure differences in inflorescence number and ∆GA3 between photoperiods. ‘Afterglow’ plants grown under SD conditions had the greatest decrease in ∆GA3 (–1.09 µg·g–1) over 48 days and the most inflorescences (10.6) compared with LD control plants with a decrease in ∆GA3 of –0.09 µg·g–1 and fewer inflorescences (1.0). Plants grown under LD conditions and treated with 0.05 mg/plant ethephon had inflorescence numbers (9.6) and levels of ∆GA3 (–0.74 µg·g–1) similar to the SD control. As ethephon rate increased to more than 0.05 mg/plant, inflorescence number on LD plants decreased and ∆GA3 increased. Exogenous ABA rates of 1 mg/plant produced inflorescence numbers (1.4) and ∆GA3 (–0.10 µg·g–1) similar to the LD control. As the rate increased, ∆GA3 increased and inflorescence number decreased. Plants treated with ABA rates of 3 mg/plant and more were defoliated and had no inflorescences.
10 pages, While food biotechnology has been widely applied and benefited the food and agriculture sector, community acceptance of biotechnology is still low. The factors that drive consumer rejection of food biotechnology have been well studied, but knowledge on the factors that drive willingness to purchase, particularly on an international level, is limited. This study aims to identify driving factors for respondents’ willingness to purchase fresh fruit produced with biotechnology, using an international survey conducted in the US, Canada, UK, France, and South Korea. While the overall willingness to purchase biotechnology produced fruit is low across countries, French consumers have the highest rate of willingness to purchase biotechnology produced fresh fruit among studied countries, followed by South Korea. The factors influencing respondents’ willingness to purchase include demographics, lifestyle, and shopping behavior. While respondents behave differently across countries, factors like environmental awareness, self-reported healthiness, and habits of eating away from home, have been found to enhance the willingness to purchase biotechnology produced fruit across countries.
18 pages., While in vitro animal meat (IVM) is not yet commercially available, the public has already begun to form opinions of IVM as a result of news stories and events drawing attention to its development. As such, we can discern public perceptions of the ethics of IVM before its commercial release. This affords advocates of environmentally sustainable, healthy, and just diets with a unique opportunity to reflect on the social desirability of the development of IVM. This work draws upon an analysis of ethical perceptions of IVM in 814 US news blog comments related to the August 2013 tasting of the world’s first IVM hamburger. Specifically, I address three primary questions: (1) How does the public perceive the ethics of IVM development? (2) How acceptable is IVM to the public relative to alternative approaches to reducing animal meat consumption? and (3) What should all of this mean for the ongoing development and promotion of IVM? Ultimately, it is argued that there is a strong need for facilitation of public dialogue around IVM, as well as further research comparing the acceptability of IVM to other alternatives.
17 pages, We examined the effect of multidimensional farmers' beliefs on the likelihood of cultivating planting materials of biofortified orange-fleshed sweet potato (OFSP) varieties. Using a panel dataset and combining difference-in-differences regression with propensity score matching, results showed positive effects of beliefs related to health benefits, yielding ability, sweetness, disease-resistance, storability, early maturity, colour, and that children enjoy eating OFSP roots, on cultivation of OFSP varieties. The proportion of OFSP roots out of total sweet potato production for a household increased among farmers' who held these beliefs. Efforts to promote biofortified crops can, therefore, benefit from taking farmers' multidimensional beliefs into consideration.
