    Notes: Activity of acetyl CoA carboxylase was determined in germinating and maturing sunflower (Helianthus annuus L.) cv. Rum Sun Record seeds. A constant decrease was observed in germi nating embryos. Exposure of etioplasts to light intensity of 500 (74 mW . cm−2) lux for different time intervals decreased the activity of the enzyme in the embryos. A reverse trend was observed in ripening embryos where the ATP-Pi exchange rate was found to be directly correlated to the activity of acetyl CoA carboxylase.

    Fatty Acid Synthesis in Hydrilla Chloroplasts (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 47 (1979), S. 0

    Notes: The rates of carboxylation, photophosphorylation and acetate incorporation have been compared in the intact and broken chloroplasts of Hydrilla verticillata Royle leaves in the presence and absence of certain inhibitors and metabolites. The intact chloroplasts showed low rates of photophosphorylation, high rates of carboxylation, and exhibited normal capacity for fatty acid biosynthesis. In broken chloroplasts a drastic decrease was observed in the rates of carboxylation and acetate incorporation. However, the rate of photophosphorylation was considerably increased. In the presence of light, inhibitors such as iodoacetamide, arsenite and sodium azide decreased the photophosphorylation rate. F-1,6-di-P and PGA stimulated CO2 fixation rate. In the absence of artificial light, inhibitors such as sodium arsenite, gluconate-6-phosphate, sodium azide and iodoacetamide decreased the rate of CO2 fixation. CoA, ATP, G-6-P, F-1,6-di-P Stimulated the synthesis of fatty acids. Exogenous supply of ADP. NADH, NADP and NADPH did not stimulate fatty acid biosynthesis probably because these compounds could not gain entry into the chloroplasts. Light was necessary for the in vitro fatty acid biosynthesis.

    Qualitative and quantitative changes in the seed and oil content ofBrassica juncea mutants at different times of harvesting (1981)
    Springer

    Notes: Abstract With increasing maturity, the moisture percentage, ‘a’, ‘b’, and total chlorophyll and crude fibre content decreased progressively, whereas oil and protein content increased. However, 1000-grain weight and pod yield increased up to stage II. Some significant correlations observed in green pod stage I were absent in the pale yellow stage II and golden yellow stage III of maturity. The positive significant correlations between 1000-grain weight and seed yield existed in both stages I and II, but there was no correlation between these characters at the golden yellow stage III. Thus mustard can be harvested at the pale yellow pod stage without any adverse effect on seed quality and yield.

    Notes: Abstract Mixtalol (a mixture of long chain aliphatic alcohols varying in chain length from C24 to C32) applied to Brassica juncea plants as foliar spray caused an increase in secondary and tertiary branching with consequent enhancement in seed yield through increased number of inflorescences and siliquae per plant. The percentage of immature siliquae and shattering of siliquae decreased with this treatment. Mixtalol increased total dry matter of plants, partitioning coefficient and harvest index. The contents of starch, protein and oil were also higher in seeds from Mixtalol treated plants.

    Notes: Abstract Plants of peanut (Arachis hypogaea L. var. PG No. 1) were given two foliar sprays of phenolic compounds (H-acid, 1, 2, 4-acid, resorcinol and RD-Brown) at 100 and 200 ppm, 35 and 50 days after sowing. In treated plants, shelling %, yield (kg/ha), number of gynophores per plant and number of pods per plant were significantly greater than in the control. Oil content of kernels also showed a significant increase with all the phenolic compounds applied. These compounds increased the linoleic acid concentration so improving nutritional quality. The number of gynophores was significantly correlated with the number of pods per plant and yield per hectare. The effect of phenolic compounds on growth and development was independent of their structural configuration.

    Notes: Abstract Seeds of thirteen genotypes of cauliflower, four of turnip and seven of radish were analysed for oil content and fatty acid composition. Turnip and radish had higher oil content as compared to cauliflower. Oleic, linoleic + eicosenoic and erucic acids were the major fatty acids in the oils of these seeds. Levels of erucic acid were in the order of radish 〈 turnip 〈 cauliflower. Compared to cauliflower and turnip seeds, radish seeds contained higher amounts of palmitic, oleic, and linolenic + eicosenoic acids and lower amounts of linoleic and erucic acids.

    Comparison of oil content and fatty acid composition of peanut genotypes differing in growth habit (1987)

    Notes: Abstract Peanut genotypes belonging to Virginia Runner, Virginia Bunch and Spanish Bunch groups exhibiting spreading, semi-spreading and erect growth habits, respectively, were compared for oil content and fatty acid composition. Mean values of oil content of the three peanut groups did not differ much, however, a marked difference was observed in fatty acid composition. Oleic acid concentrations were in the order of Virginia Runner 〉 Virginia Bunch ≧ Spanish Bunch. This trend was reverse with respect to linoleic acid concentration. Virginia Runner genotypes having higher oleic—linoleic acid (O/L) ratio and corresponding lower iodine value of oil have greater oil stability and would incur lower cost of hydrogenation. Oil of Spanish Bunch and Virginia Bunch genotypes is nutritionally better due to a higher concentration of linoleic acid and may be used as refined oil. Oleic acid concentration was negatively correlated with that of linoleic acid, suggesting that selection of genotypes in each group, with improved industrial or nutritional qualities would be possible.

    Notes: Abstract Seeds of sixty four genotypes ofBrassica campestris L. (Toria) were analyzed for oil content and fatty acid composition. Oil content varied from 38.9% to 44.6%. Major fatty acids viz. oleic, linoleic, linolenic, eicosenoic and erucic acids exhibited ranges from 10.1% to 17.3%, 5.9% to 14.5%, 5.2% to 15.0%, 7.7% to 13.7% and 39.6% to 59.9%, respectively. Compared to the standard cultivar ITSA, four genotypes contained 5 to 8% lower content of erucic acid; and six genotypes contained significantly higher content of linoleic acid. Oil was positively correlated with erucic acid. The observed inverse relationship between linoleic and erucic acid contents might be utilized in breeding nutritionally better Toria cultivars with both high linoleic and low erucic acid contents.
