“…You et al (2014) found that both linoleic and linolenic acids have a common biosynthesis pathway, so one can increase at the cost of the other. Similar findings were also reported by Bayrak et al (2010) and Pali & Mehta (2014). The results obtained in the present study indicate that high oil content will result in high oleic acid, tending to increase linolenic acid and reduce oleic and linoleic acids.…”

“…Oleic acid, in turn, had a significant positive association with oil content. However, Bayrak et al (2010) observed a positive association between palmitic acid and oil content. The negative correlations of linolenic acid with linoleic acid and of oleic acid with linoleic and linolenic acid can be best understood by the fatty acid biosynthesis pathway.…”

“…However, Pali & Mehta (2014) suggested that an increase in oil will lead to an increase in linolenic acid. Bhatty (1995) and Bayrak et al (2010) also observed a negative association of linoleic, oleic, and stearic acids with linolenic acid. Considering the obtained results, the present study suggests that selection to increase oil content would not affect linseed oil quality, since selection does not affect total fatty acid compositions, despite the noticeable changes in different fatty acids.…”

“…Although literature on the improvement of yield potential is available for linseed, few works have been carried out on improving oil quality, taking into consideration major fatty acids (Bayrak et al, 2010;Pali & Mehta, 2014). This shows the importance of characterizing the linseed germplasm for different morphological traits and for the elucidation of the fatty acid profile.…”

-The objective of this work was to evaluate the relationship among phenotypic and quality traits in a set of indigenous and exotic accessions of linseed (Linum usitatissimum). The experimental material consisted of 151 accessions of linseed belonging to landraces and cultivars collected from diverse agroecological zones. Five randomly chosen plants of each accession in each replicate were tagged, and data were recorded for the 12 following agronomic traits: days to flowering, days to maturity, plant weight, plant height, tillers per plant, secondary branches per plant, capsules per plant, seeds per capsule, 1,000 seed weight, harvest index, seed yield per plant, and oil content. Capsules per plant, harvest index, and plant weight played a direct and indirect major role on seed yield. High heritability, coupled with high genetic advance for plant weight, secondary branches per plant, capsules per plant, and seed yield per plant, suggests that selection based on these traits can be effective. Regarding per se performance, the following accessions can be exploited for commercial cultivation: Shweta (5.41 g), Gaurav (5.07 g), and EX-3-3 (4.77 g) for seed yield; and Shubhra (45.09%), Mukta (44.94%), Laxmi-27 (45.06%), and Shweta (44.25%) for oil content. The chemical profiling of fatty acids obtained in the present study can provide a platform for the selection of accessions for the genetic improvement of linseed.Index terms: Linum usitatissimum, correlation, fatty acids, genetic advance, heritability, path analysis. Relações entre características fenotípicas e de qualidade em acessos de linhaça nativos e exóticosResumo -O objetivo deste trabalho foi avaliar a relação entre as características fenotípicas e de qualidade de um conjunto de acessos nativos e exóticos de linhaça (Linum usitatissimum). O material avaliado consistiu de 151 acessos de linhaça nativos ou de cultivares obtidas de diferentes zonas agroecológicas. Cinco plantas de cada acesso, selecionadas aletoriamente, foram identificadas, e foram registrados dados para as 12 seguintes características agronômicas: número de dias para o início do florescimento, número de dias para a maturação, peso da planta, altura da planta, número de perfilhos por planta, número de ramos secundários por planta, número de cápsulas por planta, número de sementes por cápsula, peso de mil grãos, índice de colheita, produção de sementes por planta e conteúdo de óleo. O número de cápsulas por planta, o índice de colheita e o peso da planta desempenharam papel importante tanto direta quanto indiretamente na produção de sementes. Altos valores de herdabilidade, associados a alto avanço genético para peso da planta, número de ramos secundários por planta, número de cápsulas por planta e produção de sementes por planta, sugerem que a seleção com base nestas características pode ser eficaz. Em relação ao desempenho per se, os seguintes acessos podem ser explorados em cultivo comercial: Shweta (5,41 g), Gaurav (5,07 g) e EX-3-3 (4,77 g) para produção de sementes; e Shubhra (45,...

Plant oil triacylglycerols are attractive renewable resources for biobased epoxy resins. We investigated the curing kinetics of three model epoxidized fatty acid methyl esters and representative epoxidized triacylglycerols with varied epoxide functionalities and distributions in the presence of a latent cationic initiator. Isothermal differential scanning calorimetry (DSC) was used to analyze the curing kinetics of the epoxy systems, and kinetic parameters (i.e., rate constants, reaction orders) were determined. Both epoxidized fatty esters and triacylglycerols followed the autocatalytic curing mechanism, and the DSC data were analyzed according to the Kamal autocatalytic model. Epoxidized methyl linoleate (EMLO) had the highest maximum curing rate, followed by epoxidized methyl linolenate (EMLON), and epoxidized methyl oleate (EMO) had the lowest maximum curing rate. We conclude that EMLO with two epoxide groups has the highest reactivity in this curing system, while the EMO with one epoxide group has the lowest reactivity. For epoxidized triacylglycerols, epoxidized camelina oil had the highest curing reactivity at higher temperatures, followed by epoxidized linseed oil and soybean oil.

An innovative biolubricant for gears/wheel‐rail systems is formulated; it is produced inexpensively using high‐viscosity vegetable oils modified with additives of unpurified carbon nanopearls (CNPs) and MWCNTs produced via carbon‐vapor deposition. Traditional lubricants made from non‐renewable sources can be replaced with such additive‐based oils. The addition of both unpurified carbon nanopearls and nanotubes containing nanoparticles of Fe, Ni, Co, or SiO2 is a simple way to improve the tribological properties of biolubricants. Therefore, carbon nanostructures used as additives are not required to be purified or functionalized, thus reducing production costs. Tribological testing is performed with ball‐on‐disc, four‐ball, and twin‐disc machines for two high‐viscosity biolubricants. A complex rosin ester and linseed oil additivated with commercial and raw CNPs/MWCNTs are tested. Scanning electron microscope characterization is used to assess the morphology and structure of both the carbon nanopearls and the multiwalled carbon nanotube particles in addition to the worn metal surfaces. Additionally, X‐ray diffraction, FTIR spectroscopy, and inductively coupled plasma atomic emission spectroscopy are used to characterize the MWCNTs additives. Practical Applications: Biolubricant additivation with raw unpurified MWCNTs and CNPs for enhanced tribological performance. Presence of Fe, Ni, Co, and Si nanoparticles helps fine‐tune the friction coefficient and anti‐wear rates. The proposed method may prove useful in biolubricant formulation for applications in gears/wheel‐rail and metal machining systems.
