The objective of the study was to find whether consumers declare an intention to eat bread enriched with fiber in the situation of availability of a plain bread and plain bread with grains, and how these intentions are related to their awareness of fiber in bread. The data were collected in a cross-sectional survey among 1014 Polish adults. Based on three pictures of rolls: plain wheat roll (CR), roll enriched with 12% fiber (RF), and roll topped with sunflower seeds (RSS), the participants’ perception regarding fiber content and its impact on intentions to eat were assessed. The respondents were not informed about the differences in composition of the rolls. Although RSS contained only slightly more fiber (0.98 g) than CR (0.81 g), and much less than RF (3.08 g), most of the respondents indicated RSS as containing the most fiber (50.8%) and declared their intention to eat it (39.0%). Respondents who pointed out the importance of fiber, and grains or wholemeal flour addition when making purchase decision, were more likely to declare an intention to eat RSS compared with CR. The low interest in fiber content in a diet increased the chances of declaring an intention to eat CR and RF. People less educated and with low incomes were more likely to declare an intention to eat CR rather than RSS. While people from rural areas were more likely to choose RSS compared with CR and RF. In conclusion, there is interest in bread enriched with fiber, but consumers experience difficulties in recognizing it. Declared intentions to eat each rolls were determined to the greatest extent by the perception of the roll as source of fiber. Thus, educational activities should be focused on consumers’ perception of fiber-rich products and their skills related to the selection of high-fiber foods.

Insight Into

The societal and economic benefits of ecosystem services are both immense and multi-faceted. To holistically quantify the contribution of pollinators to agriculture requires measuring multiple indices of crop production beyond crop yield. Here, we conduct a field-based hand pollination experiment to measure the effects of self and outcross pollen on fiber yield and quality in conventionally managed cotton crops. First, we determine how different pollination treatments affect specific indices of fiber yield and fiber quality, including fiber length and fineness. Second, we investigate the suggested tradeoff between fiber yield and quality. We find that flowers receiving outcross pollen produce larger, heavier bolls than either self-crossed or non-crossed flowers. However, contrary to expectation, flowers of different treatments are indistinguishable in terms of fiber quality. Overall, we find that pollination treatment has no discernable effect on either fiber length or fiber fineness. Understanding the contribution of ecosystem services across multiple axes provides growers with information concerning potential tradeoffs or synergies, and offers insight into management decisions.

Cotton Fiber Quality

Saw-type lint cleaner (STLC) was most efficient lint cleaner in cotton ginning. However, STLC damaged fiber quality. An air-bar lint cleaner (ABLC) was developed and evaluated to preserve cotton fiber quality. The ABLC used pressurized-air to remove non-lint materials from cotton fiber. During lint cleaning process, non-lint materials attached to the fiber were blown off the fiber without the fiber making aggressive mechanical contact with a grid bar in conventional saw-type lint cleaner (STLC). It was expected using this concept that the fiber quality could be preserved by reducing the damage from mechanical impact of the fiber against the grid bar. Preliminary testing of the ABLC prototype showed that ABLC generated less lint waste and had a higher turnout rate than STLC. Use of ABLC could save 2.8 kg of lint in each 225 kg bale of cotton. The High Volume Instrument (HVI) analysis indicated the fiber properties in fiber length, uniformity, short fiber content, and color were not significantly different between ABLC and STLC. However, the Advanced Fiber Information System (AFIS) tests showed STLC had better performance than ABLC in fiber length and short fiber content while the trash and dust content with ABLC was lower than the STLC. More research was necessary to further prove the concept of ABLC and improve its performance in preserving cotton fiber quality.

With the growing aridity of the climate on the Don, it became necessary to improve the methodology for conducting the  breeding of spring durum wheat. The main method of obtaining the source material remains intraspecific step hybridization. Crossings were performed between genetically distant forms, differing in origin and required traits and properties. The use of chemical mutagenesis was a productive way to change the heredity of genotypes in terms of drought tolerance. When breeding for productivity, both in dry years of research and in favorable years, the most objective markers were identified — the size of the aerial mass, the mass of grain per plant, spike, and harvest index. The magnitude of the correlation coefficients between the yield per unit area and the elements of its structure is established. It was most closely associated with them in dry years, while in wet years it decreased. Power the correlation of the characteristics of the pair - the grain yield per square meter - the aboveground biomass averaged r = 0.73, and in dry years it was higher (0.91) than in favorable ones (0.61 - 0.70) , between the harvest and the harvest index - r = 0.81 (on average). In dry years, the correlation coefficient increased to 0.92. Research data confirms the greatest importance of the mass of grain from one ear and the plant in the formation of grain yield per unit area in both dry and wet years. In dry years, the correlation coefficient between yield and grain mass per plant was on average r = 0.80; in favorable years, r = 0.69. The relationship between yield and grain mass from the ear was greater — r = 0.84 and r = 0.82, respectively. Consequently, the breeding significance of the aboveground mass and the productivity of the ear, as a criterion for the selection of the crop, especially increases in the dry years. They were basic in the selection.

AbstractThis article provides a theoretical framework for analyzing the recruitment and selection of legislative candidates in Latin America. It argues that political recruitment and candidate selection are undertheorized for Latin America yet have determinative impacts on political systems, often overriding the influence of more commonly studied institutional variables. The article elucidates a typology of legislative candidates based on the legal and party variables that lead to the emergence of particular selection methods, as well as the patterns of loyalty generated by those methods. It analyzes the recruitment and selection processes as independent and dependent variables, underscoring the significant effect these procedures have on the incentive structure and subsequent behavior of legislators. Those factors, in turn, have important consequences for democratic governability and the performance of presidentialism.

Abstract: The objective of this work was to evaluate the oil content and characters related to fiber quality and yield in cotton lines (Gossypium hirsutum), in order to select genotypes with high oil content and acceptable levels of the other characters. Twenty-two F6 lines and three checks were cultivated in three field trials - two in the municipality of Apodi, in the state of Rio Grande do Norte, and one in the municipality of Barbalha, in the state of Ceará, both in Brazil. The genetic parameters and the genetic gain from selecting 20% of the lines were estimated according to their means in each environment and in the group of environments. Regarding oil content, there is genetic variability, and the selection based on the overall mean is indicated, since this character showed high heritability, with 4.58% expected gain. The lines selected with this criterion have oil contents between 23.52 and 24.51%, which are higher than those of the Brazilian cultivar BRS Aroeira with the highest grain oil content (22.04%).
