AbstractEven though the sunflower is the second most widespread oil plant in the Czech Republic, there is a lack of information about the effects of climate, nitrogen and micronutrients application on sunflower oiliness and fatty acid composition of sunflower achenes. To obtain such information, we established five year experiment (2008–2012) to study the effect of climate, nitrogen (C-control, N 60–60 kg N ha−1, N 90–90 kg N ha−1, N 120–120 kg N ha−1) and of foliar application of boron (N 90 + B), zinc (N 90 + Zn) and molybdenum (N 90 + Mo) on sunflower oiliness and composition of fatty acids (palmitic, palmitoleic, stearic, oleic and linoleic acids). According to our results, oiliness and fatty acid composition was significantly influenced by climate and fertilizer treatment. Oiliness was influenced mainly by climate (96.4%), the effect of fertilizer treatment was minor (2.5%). Within the frame of climate, the effect of precipitation was slightly higher than of temperature. A strong and negative relationship between the dose of nitrogen and oiliness was revealed (r = –0.79), the difference between C and N 120 treatment was 2.1% on behalf of C treatment. The highest oiliness was recorded in 2011 (50.72%) and in C treatment (48.48%). The fatty acid composition was not significantly influenced by fertilizer treatment, but was significantly influenced by the climate conditions of the year. Application of micronutrients was not connected with any significant increase in oiliness or in the fatty acid composition due to a high initial content of those micronutrients in top soil.

The fatty acid and antioxidant property of pawpaw coconut oil (PCO) and virgin coconut oil (VCO) were compared. GC and GC-MS were used to determine the fatty acid of PCO and VCO, respectively. The results show that there is no obvious difference of fatty acid composition between PCO and VCO. The scavenging rate to ABTS+• of PCO is higher than VCO at the same proportion. TEAC (Trolox equivalent antioxidant capacity) value of PCO is 67.5µmol/l. The complexing ability to Fe2+of PCO is stronger than VCO at the same proportion. The scavenging ability to DPPH• of 40% PCO is weaker than VCO, with the increase of PCO concentration, the difference of the scavenging ability to DPPH• between PCO and VCO is smaller.

Twenty plant-derived and 18 non-plant-derived strains of Lactobacillus casei were compared for their growth in tryptone – yeast extract – glucose broth containing 0.3% bile by measuring absorbance at a wavelength of 620 nm after 24 h of incubation at 37 °C. Bile tolerance — a fundamental probiotic property — was calculated by dividing the experimental data by control values (growth without bile). We found that bile tolerance was strain specific but that the average bile tolerance of the plant-derived strains was significantly (P < 0.05) lower than that of the non-plant-derived strains tested. All tested strains could not deconjugate sodium taurocholate, indicating that the difference in bile tolerance was not due to the ability to deconjugate bile. The fatty acid compositions of the test strains with and without exposure to 0.3% bile were investigated, and a statistical correlation analysis between these compositions and their bile tolerance was conducted. The fatty acids correlated with bile tolerance differed between plant and non-plant lactobacilli. This is the first report to show that the origin (i.e., growth environment) of lactobacilli affects their fatty acid composition, which in turn, appears to be related to their bile tolerance.

SummaryTwo breed comparisons were made: (a) between Galway and Galway x Finnish Landrace (Fingalway) lambs, and (6) between Galway x Fingalway and Galway x (Finn x Texel) lambs, for the melting point and fatty acid composition of subcutaneous tail, subcutaneous 13th rib and perinephric fat. The lambs were slaughtered at market weight from September to January, being finished off on grass except for a small number finished indoors on concentrates and hay.Slaughter age and carcass weight, both of which had significant effects on some of the measurements, were included as covariates in the breed comparisons. Overall breed effects were small. The melting point of the fat from Fingalway lambs was lower than that of the Galway breed in each location, the difference being significant for subcutaneous rib fat. This was associated with a lower concentration of stearic acid and a higher concentration of oleic acid in each fat depot of the Fingalway breed, the difference being significant for oleic in subcutaneous tail and for stearic in subcutaneous rib fat. No significant breed differences or trends were observed for the other fatty acids measured. Results for a small number of pure Finn lambs supported the Finn ancestry influence indicated by comparison (a). In the second breed comparison, no significant breed differences were observed, the values being close to those obtained for the pure Galway lambs.

Ridomil MZ alone or Ridomil MZ followed by protectant fungicides was tested to manage white rust (Albugo candida) (Pers. ex Lev.) Kuntze on Brassica juncea L. var. RL-1359, sown at the normal time in 1989–90 and 1990–91 and under delayed sown conditions in 1990–91 at 2 different geographical locations of the Punjab state. Two spray applications of aqueous suspension of Ridomil MZ at 450 g a.i./ha or 1 foliar application of Ridomil MZ at 450 g a.i./ha, followed by another spray of Dithane M-45 at 600 g a.i./ha or Blitox-50 at 375 g a.i./ha at 15- or 20-day interval to a 70-day-old crop significantly reduced both foliage and floral infections. These treatments significantly increased the seed yield over control and other treatment combinations, without having an adverse affect on the oil content and fatty acid composition of the oil. The same fungicide regime was effective to control white rust when applied to a 50- or 60-day-old crop under delayed sown conditions. The seeds harvested from the plots treated twice with Ridomil MZ exhibited no detectable residue of metalaxyl and mancozeb. The timing of application of these fungicides may be critical in the control of white rust, particularly in the late sown crop.

Total lipids, triglycerides, and phospholipids from several lots of beach-spawning capelin and one lot of prespawning, offshore capelin have been determined and examined in detail for fatty acid composition. Generally, but not invariably, female fish contain more fat, the difference being apparent in the triglycerides. These are also usually of higher iodine value than triglycerides in the males. During frozen storage the lipids, including triglycerides, in most samples of male capelin undergo more severe hydrolysis than in the females. It is believed that these phenomena are related to bioenergetic relationships by which the males require very rapid catabolism of depot fat and hence nonspecific hydrolysis of fatty acids, whereas the less active females show some selectivity and preferentially catabolize the longer-chain monounsaturated fatty acids.When allowances are made for 16:1 and 18:1 being interchangeable, Newfoundland capelin triglycerides are shown to be essentially similar to eastern Atlantic commercial capelin oil, and may be distinguished by certain composition characteristics from other Canadian commercial oils of comparable iodine value. Details of fatty acid compositions are summarized for nutritional evaluation of capelin and capelin products.

Cucumber (Cucumis sativus) seed oil has the potential for use as an edible oil and as a pharmaceutical, cosmetic, insecticidal, and industrial product. In this study, we investigated, for the first time, the effect of cultivar and season on seed number, oil content, and fatty acid profiles as well as their proportions in different cucumber cultivars. We examined the effects of spring and autumn seasons on seed oil content and fatty acid composition in 46 cucumber cultivars and one wild species of cucumber (C. anguria) grown in greenhouse experiments in 2013 and 2014. Seed oil was determined using the Soxhlet method and fatty acids using the gas chromatography-mass spectrometry method. Seed oil content in the cucumber seeds ranged from 41.07% in ‘Hazerd’ to 29.24% in ‘Lubao’ while C. anguria had 23.3%. Fatty acids detected were linoleic (C18:2), palmitic (C16:0), oleic (C18:1), stearic (C18:0), linolenic (C18:3), behenic (C22:0), arachidic C20:0), lignoceric (C24:0), eicosenoic (C20:1), palmitoleic (C16:1), and myristic (C14:0), among other unidentified fatty acids. The results showed significant effects of cultivar genotype, growing season, and interactions on the variables examined. The content of seed oil and fatty acids differed significantly among the cultivar genotypes. Spring-grown cucumbers had higher quantities of oil than the autumn-grown cucumbers. The content of fatty acids (mainly palmitic, palmitoleic, stearic, oleic, eicosenoic, and lignoceric) also was higher in spring. In autumn there were more seeds, and higher linoleic, linolenic, and other unspecified fatty acids. The higher the oleic acid content the lower was the linoleic acid indicating a strong negative relationship in these two fatty acids. The higher the seed oil content the higher was linoleic and oleic indicating a positive relationship between the seed oil and the two fatty acids. Results of this study provide important information applicable in improving management and production of cucumber seed oil especially considering its versatility in uses. Furthermore, the wide range of fatty acids found in the studied cucumber cultivars could be used in the production of novel industrial oils through genetic engineering.

The effect of irrigation and nitrogen fertilizer levels on the crude oil and fatty acid composition of maize cultivars was studied. Three levels of irrigation (50, 75 and 100% of field capacity) and nitrogen (100, 200 and 300 kg·ha-1) were used for treatment groups. After harvest, the crude oils were extracted and fatty acid profiles were determined by Gas Chromatography system. The study was repeated for two years and the interaction effects of fertilizer and irrigation were determined. Our results show that the crude oil content was affected positively by the fertilizer and the irrigation applications. As expected, the most abundant fatty acid was linoleic and the harvest year did not alter it. The highest linoleic acid content value was obtained with a 50% field capacity and 300 kg·ha-1 fertilizer treatment combination. In addition, fatty acid contents varied with the changing of interaction effects except for myristic and palmitic acid. Oleic acid was the second abundant fatty acid in the oil samples and the lowest oleic acid value was obtained with a 50% field capacity and 300 kg·ha-1 fertilizer treatment combination. Oleic acid content tended to increase with 75% field capacity but 100% field capacity treatment decreased in it.

Boron is a member of the metaloid group of elements and is an important essential microelement needed for normal crop growth and development. This research was conducted in 2015 in Hatay (Mediterranean region of Turkey) to determine foliar application of Boron effect on protein ratio, starch ratio and oil yield and oil components of corn. To evaluate the response of foliar application of boron to corn, four boron doses (control, 4, 6 and 8 mg/m2) were applied at the three growing stages (V2; 2 leaves with visible collars, V4; 4 leaves with visible collars,V2V4; half dosage was applied V2 and half dosage was applied V4). The experiment was carried out in a split plot design with three replicates using cultivar 82 May 70. Ears were harvested and randomly selected for analysis of protein ratio, starch ratio, oil yield and fatty acid composition. Even though there was no significant difference in Boron treatments in terms of protein and starch, significant difference was determined in oil yield and fatty acid composition. In general, foliar application of higher Boron doses (6, 8 mg /m2) increased oleic acid, palmitic acid, stearic acid. In the early development period (V2), foliar application of boron caused an increase in the content of linoleic acid and linolenic acid of corn.
