The effects of different boron (B) dosages (0, 2 and 12 mg B/kg) were determined on four soybean (Glycine max (L.) Merr.) cultivars, namely 13935, Türksoy, ME 3399 and Deficiency. B contents of the dried plant samples, dry weight, total oil, biomass, seed yield (g/pot), seed protein contents and seed fatty acid compositions were estimated. The seed protein content and shoot dry weight of soybean cultivars increased and decreased with B supply, respectively. The seed oil of cv. Türksoy had the highest ratio of stearic and oleic acids under 2 mg B/kg treatment. The highest total oil content under 12 mg B/kg treatment was observed in cv. Deficiency with 8% higher total oil content. The ratio of saturated fatty acids to unsaturated fatty acids decreased in cvs. 13935 and ME 3399, and increased in cvs. Türksoy and Deficiency at B treatments. Seeds oil of cvs. 13935 and ME 3399 showed the highest α-linolenic acid levels under 2 mg B/kg and 12 mg B/kg soil treatment, respectively. The study revealed that high concentrations of boron had a diminishing effect on seed yield (except cv. Türksoy), increasing effect on protein content and variable effect on saturated and unsaturated fatty acid compositions. This specifies the involvement of boron in the formation of seed protein and fatty acids in soybean. However, detailed research is required to understand the mechanisms behind the process.

This study was carried out to determine the efficiency of nitrogen (N) doses (0, 30, 60, and 90 kg N ha−1) under supplemental potassium (K) application (50 kg K2O ha−1) on black cumin in 2011 and 2012. The results showed that increased N levels resulted in increasing seed yield and N and K contents in seed, while oil content decreased. The seed yield and oil yield were peaked at the doses of 60 kg N ha−1and 50 kg K ha−1. An increase in N doses caused a reduction in oil content regardless of K supply. Saturated fatty acids and oleic acid were slightly increased by K application, while minor changes in linoleic acid were detected. It was concluded that 60 kg N ha−1with supplemental K application should be advised for enhancement in seed yield, oil yield, and N and K contents in seeds of black cumin without significant changes in fatty acid composition.

Abstract Seed samples of some rape and canola cultivars were analysed for oil content, fatty acid and tocopherol profiles. Gas liquid chromotography and high performance liquid chromotography were used for fatty acid and tocopherol analysis, respectively. The oil contents of rape and canola seeds varied between 30.6% and 48.3% of the dry weight (p<0.05). The oil contents of rapeseeds were found to be high compared with canola seed oils. The main fatty acids in the oils are oleic (56.80–64.92%), linoleic (17.11–20.92%) and palmitic (4.18–5.01%) acids. A few types of tocopherols were found in rape and canola oils in various amounts: α-tocopherol, γ-tocopherol, δ-tocopherol, β-tocopherol and α-tocotrienol. The major tocopherol in the seed oils of rape and canola cultivars were α-tocopherol (13.22–40.01%) and γ-tocopherol (33.64–51.53%) accompanied by α-T3 (0.0–1.34%) and δ-tocopherol (0.25–1.86%) (p<0.05). As a result, the present study shows that oil, fatty acid and tocopherol contents differ significantly among the cultivars.

Abstract Now days, production of fuels and petrochemicals from renewable lignocellulosic biomass is an indispensable issue to meet the growing energy demand. Meanwhile, the changes in the climate and soil topography influence the growth and development as well as canopy level of the lignocellulosic biomass. In this study, Zilla spinosa Turr (Zilla) plants with similar age and size were collected from three main sectors (upstream, midstream, and downstream) of Wadi Hagul during spring (April) and summer (July) seasons. Environmental stresses evoked reduction in the energy trapping pigments concomitant with increments in chlorophyll fluorescence in summer harvested plants particularly at downstream. Furthermore, the biofuels generating compounds including carbohydrate, lignin, and lipid making the plant biomasses are greatly affected by environmental conditions. Greater amount of lignin was estimated in summer harvested Z. spinosa shoots particularly at downstream. Moreover, the total oil content which is a promising source of biodiesel was considerably decreased during summer season particularly at downstream. The physical properties of the lipids major constituent fatty acid methyl esters determine the biofuel properties and contribute in the adaptation of plants against environmental stresses. Hence, the analysis of fatty acid profile showed significant modifications under combined drought and heat stress displayed in the summer season. The maximum increase in saturated fatty acid levels including tridecanoic acid (C13:0), pentadeanoic acid (C15:0), palmitic acid (C16:0), and stearic acid (C18:0) were estimated in spring harvested Z. spinosa aerial portions particularly at midstream. In spite of the reduction in the total oil content, a marked increase in the value of unsaturated to saturated fatty acids ratio and thereby the unsaturation index were achieved during the dry summer period. Henceforth, these seasonal and spatial variations in fatty acids profiles may contribute in the acclimatization of Z. spinosa plants to soil water scarcity associated with heat stress experienced during summer. In addition, the alterations in the fatty acid profiles may match biofuel requirements. In conclusion, the most adequate growing season (spring) will be decisive for achieving high lipid productivity associated with improved biofuel quality in terms of high saturated fatty acids percentage that improves its cetane number. However, the dry summer season enhanced the accumulation of greater amount of lignin that may enhance the biodiesel quantity.

Paeonia ostii is recognized as an important oilseed tree peony species with potential as a raw material source for cosmetic and health care products, strong seed setting capacity, high seed oil yield, and abundant omega-3 polyunsaturated fatty acids. P. ostii, commonly called Fengdan, is widely cultivated in China. The cultivation method difference has an important influence on the oil-use feature, which is a key index for evaluating the quality of oilseed crops. This study aimed to select an optimal cultivation method to provide the first reference data for high-yield and high-quality seed oil harvesting and to facilitate the understanding of the quality difference in the formation mechanism of seed oil in cultivated P. ostii. This study selected five representative cultivation methods, open field cultivation, sunny slope cultivation, shady slope cultivation, understory intercropping cultivation, and high-altitude cultivation, and investigated the influence of cultivation method differences on the oil-use feature based on the three aspects of seed yield traits, oil yield, and fatty acid compositions. Six seed yield traits (fruit pod length, fruit pod width, fruit pod thickness, number of fruit pods per plant, 1000-grain weight, and seed yield per plant) and oil yield reached the maximum values of 7.75 cm, 6.99 cm, 1.57 cm, 11.33, 290.45 g, 85.8 g, and 30.41%, respectively, using the understory intercropping cultivation method. Fatty acid compositions were mainly identified as α-linolenic acid, linoleic acid, oleic acid, stearic acid, and palmitic acid, with significant content differences among different cultivation methods (P < 0.05). Functional component α-linolenic acid and total amounts of unsaturated fatty acids reached the maximum values of 46.85% and 65.23%, respectively, with high-altitude cultivation and understory intercropping cultivation. The seed yield traits, oil yield, and total amounts of unsaturated fatty acids were optimal with the understory intercropping cultivation method, whereas high-altitude cultivation was conducive to the accumulation of α-linolenic acid. Understory intercropping cultivation with appropriate altitude increases is recommended as a preponderant cultivation method for high-yield and high-quality seed oil harvesting for this crop.

The oil content and fatty acids profile of a number of Polish wild species of rose fruits were examined by GC. The total fatty acid contents ranged from 6.5% to 12.9% of dry mass in fruits. The composition of oils was similar in the investigated species. 17 components were identified. An average composition was estimated as follows: linoleic acid (44.4-55.7%), a-linolenic acid (18.6-31.4%), oleic acid (13.5-20.3%), palmitic acid (2.3-3.3%), stearic acid (1-2.5%), octadecenoic acid (0.38-0.72%), eicosenoic acid (0.3-0.7%), eicosadienoic acid (0-0.16%), erucic acid (0.03-0.17%) and minor fatty acids. The results indicate that rose fruits are a rich source of unsaturated fatty acids, especially in <em>R. rubiginosa</em>, <em>R. rugosa</em> and <em>R. dumalis</em>. There were statistically significant (p&lt;0.05) differences in fatty acid compositions of some species. Fatty acids were suggested to have a potential chemotaxonomic value in this genus.

Development of a variety having high oil content and desirable fatty acid compositions is a major objective of groundnut (Arachis hypogaea L.) breeding programmes. To study the gene action (through combining ability) and heterosis for oil and fatty acids, an experiment was conducted using a 4 × 4 full diallel method. Four parents and their 12 F1 hybrids were evaluated following a randomized complete block design. Data were recorded for oil, fatty acids and oleic-linolenic (O/L) acid ratio. Highly significant genotypic variation was found among the parents and their F1 hybrids for the studied traits. The combining ability studies (general, specific and reciprocal) reflected that the oil and fatty acid traits were controlled by both non-additive and additive genes having significant maternal effects. Results also revealed that the parent China Badam was the best general combiner for oil, linolenic acid and O/L ratio whereas the parent Binachinabadam-4 for oleic and linoleic acids. Best SCA performance was found from the cross Dacca-1 × China Badam and Binachinabadam-4 × China Badam for oil, oleic- and linolenic-acid contents. Significant heterosis for oil content was observed in F1 hybrids obtained from the cross Binachinabadam-4 × China Badam and its reciprocal cross. The cross China Badam × GC (24)-1-1-1 showed a higher O/L ratio (>4) along with lower level of saturated fatty acids. Therefore, these crosses could be exploited in future breeding programmes to develop new lines for higher oil and healthy fatty acid compositions.

The oil content and fatty acid composition were determined in the seed of 19 poppy genotypes (both landraces and modern cultivars) grown in three-year field trials. The total oil content ranged from 34.56–44.76%. The oil content in white-seeded genotypes (40.73–44.76%) exceeded the oil content in blue-seeded genotypes (34.56–40.34%) and ocher-seeded genotypes (38.36–42.69%). Linoleic acid (71.41–74.02%), oleic acid (12.35–15.51%) and palmitic acid (8.95–10.29%) were the most abundant fatty acids in the evaluated seeds of poppy genotypes. A significant negative correlation (–0.7574**) was found between linoleic and oleic fatty acids. The sum of polyunsaturated (PUFA), monounsaturated (MUFA) and saturated (SFA) fatty acids ranged from 72.43–74.91%, 12.90–16.14% and 10.99–12.46% of the total fatty acids, respectively. Both the total oil content and the content of individual fatty acids were mainly affected by the crop year (weather conditions); however, the effect of genotype and year × genotype interaction was also significant. Due to the favourable composition of fatty acids, the evaluated poppy genotypes can be<br /> a good source of nutritionally valuable oil.

Maturation of sunflowers was recorded in two field sowings at Armidale, New South Wales. Measurements were made to define anthesis, the accumulation of dry weight, oil and fatty acids in the achenes and to determine moisture contents and crop appearance associated with achene maturation. It is suggested that anthesis may be described either as its mid-point, i.e. when 50% of capitula exhibit anthesis over half their area, or by its spread, i.e. the time between 50% of capitula commenced anthesis and 50 %completed anthesis. Maximum achene dry weight was reached in the field when the achene moisture content was about 40 and the capitulum moisture content was about 70%. Both achene oil content and the content of the major polyunsaturated fatty acid (linoleic) reached their maxima at about the same time as achene dry weight in the field and this point was thus defined as 'physiological' maturity for sunflowers. It corresponded to when about ten per cent of capitula had turned brown. Production of linoleic and oleic acid was found to predominate in the later stages of achene maturation in both field sowings.

Soybean (Glycine max), a multipurpose crop with much appreciated nutritional and functional properties, has generated a lot of interest during last few decades for improving its cultivation and characteristics. Besides having a great potential of energy-protein malnutrition eradication, it can contribute greatly to edible oil pool in the region. This study investigates some agro-morphological characters, besides seed oil content and fatty acid composition of two local soybean genotypes labeled as S/D-18 and S/D-22 grown under rainfed conditions of Kashmir Himalayas in India. The genotype S/D-22 matured earlier than that of S/D-18. Seed yield/plant of 18.5 g (S/D-18) and 20.1g (S/D-22) was recorded in these genotypes with 100-seed weight of 14.3 g and 14.7 g respectively. Seeds of genotype S/D-18 yielded an oil content of 19.54% while in genotype S/D-22 oil content of 19.74% was recorded. Fatty acids of myristic, palmitic, stearic, oleic, linoleic and linoleinic were detected and quantified in the oil extracted from the seeds of these genotypes. Saturated fatty acids constituted 11.88%(S/D-18) and 11.42%(S/D-22) while unsaturated fatty acids constituted 88.12% (S/D-18) and 88.58% (S/D-22) of the oil. The study has thus, revealed that under dry land conditions, although soybean seed yield/plant is lesser, percentage oil content and fatty acid composition essentially remained unaltered and that significant differences can occur in individual fatty acid contents between genotypes.

Soybean (Glycine max L. Merrill) is one of the most important crops worldwide. In several European countries such as Germany, soybean cultivation is not traditional and as such remains to be optimized. One option to increase soybean production is to adapt and improve the seeding system. To investigate the effects of different seeding systems on seed yield, seed protein, and oil content, plant characteristics were assessed using a two-factorial (two seeding systems and four cultivars) field trial over two years (2017–2018) at two locations in southeast Germany. The seeding systems were drill (row spacing 14 cm) and precision seeding (row spacing 28 cm), and the cultivars were Viola 000, Lissabon 000, ES Mentor 00, and Orion 00. Depending on the seeding system, a seed yield of 3.8 t ha−1 dry matter (DM), 40.9% protein content (DM), and 18.8% oil content (DM) was achieved by drilling, and 3.6 t ha−1 yield (DM), 40.1% protein content (DM), and 19.1% oil content (DM) with precision seeding (average across four cultivars, two locations, and two years). No significant effects of the seeding system on all seed and plant characteristics were observed. As drilling and precision seeding did not affect the seed yield, seed protein, oil contents, and plant characteristics of soybean in this study, farmers are able to choose the seeding system which fits best into their farms and is economically most viable.
