Color Association

The association of achene color with other achene characters and bird preference was investigated in segregates of a striped Yugoslavian line NS 39 and in 12 crosses of various genotypes. In the NS 39 segregates, the strongest association of achene color was with kernel content (r = 0.606), bird preference (r = 0.610) and achene oil (r = 0.445). Birds preferred lines with darker achene color which in turn was linked with higher oil and nutmeat content. In the crosses of various genotypes, achene color was strongly associated with achene oil content in segregates of two grey × black achene color crosses (r = 0.436 and 0.292) and in segregates of anthocyanin-containing × black achene color cross (r = 0.419). Key words: Sunflower, color association, achene characters, bird preference, achene oil, nutmeat anthocyanin

Kernel Content

Oil content of the sunflower achene is determined by its components, namely kernel content and kernel oil content. The object of this study was to determine the heterosis and relative contributions of the parents to the achene oil, kernel oil and kernel content of the hybrid. Multiple regression equations showed that the two parents contribute equally to the achene oil content of the hybrids. Heterosis was observed in the kernel oil content and kernel content as well as the achene oil content. A heterotic effect of 47 g kg−1 over the mid-parent value was observed for achene oil content. For the achene oil components, heterotic effect of 44 g kg−1 was obtained for kernel oil content and 24 g kg−1 higher for kernel content.

The influence of transplanting time on the growth of evening primrose (Oenothera biennis L.) was investigated for 3 yr. Delaying transplanting reduced the yield of seed in two of these years. The amount of oil in the seed was not influenced by time of transplanting, and only in one year did the γ-linolenic acid content of the oil decrease with delays in transplanting.

AC Morgan is a high-yielding spring oat (Avena sativa L.) cultivar developed by Agriculture and Agri-Food Canada, Lacombe Research Centre, Lacombe, Alberta and released in 1999. It is described as a medium maturing cultivar with strong straw, plump kernels, high test weight, high protein content, low hull content and high milling yield. It also has low oil content, which is a desirable feature in milling oat cultivars. AC Morgan is well adapted to Alberta and the rust-free areas of Saskatchewan.

The performance of mustard (Brassica juncea (L.) Coss) was compared with that of canola (B. napus L. and B. rapa L.) on the western prairies. Mustard had a higher yield and protein content and was intermediate in maturity. Improvement in oil content will probably be required. Key words: Mustard, Brassica juncea, edible oil crop

The infiltration of a light nonaqueous phase liquid (LNAPL) into an unsaturated porous medium will result in varying amounts of water, LNAPL, and air within the soil voids. A simple and reliable method of determining the percent saturation of each fluid is needed to analyze laboratory infiltration experiments. This note reviews the available methodologies for determining the oil content in porous media and presents an experimental study of a simple and reliable method for determining water and oil contents in an unsaturated fine to medium sand. Key words: fluid saturations, oil content, gravimetric, extraction, assay.

Kernel Content

The nitrogen content of oats depends chiefly on the nitrogen content (1·4–3·9%) of the kernel and the kernel content (64–81%) of the oats, the husk containing only 3–10% of the total nitrogen in the grain.Varietal differences are significant but small in comparison with the overall variability: they reach 0·3% nitrogen in a few cases. Variation between random samples is largely due to soil differences, with region and harvest year responsible for smaller effects. The predominant factor governing nitrogen level in oats of all varieties probably is, as for wheat, the level of available nitrogen in the soil in late spring and early summer, just prior to heading and during development of the grain.Within the variety there is a pronounced inverse correlation between nitrogen and oil content which is independent of grain size: the variability of the oil content within the variety is, however, smaller than the corresponding variability of the nitrogen content. At some localities environmental factors of soil and season, particularly the former, inhibit the filling out of the grains which then ripen prematurely to give small oats with lean kernels of high nitrogen content, and favour within the variety a negative correlation between grain size and nitrogen which otherwise might not be apparent.

Head Rot

The effect of sunflower head rot on impurities in the harvested product (HP), oil content (OC) and oil acidity (OA) was studied. Levels of 0,10, 20, 30, 40, 50,80 and 100% of disease incidence (Dl) were analyzed. The HP was either weighed and left untouched or it was divided into three fractions: seeds, sclerotia and other impurities. For OC and OA measurement, we analyzed samples from each Dl level composed of seeds (S), seeds and scleratia (S+Sci), seeds and other impurities (S+Ol), and untouched original samples (S+Sct+Ol). Disease incidence significantly affected the composition of the harvested product. At greater Dl levels, seed percentage went down and impurities rose. Sclerotia were the most abundant impurities. With 100% Dl, seed represented 65% and sclerotia 25% of the HP. At greater Dl ievels, OC went down and OA rose. Content of seeds in the HP defined OC. Sclerotia content was the main reason for the increase in OA. At 100% Dl, S+Scl samples yielded 31% Jess OC and 53% more OA than the S samples.

Two early-maturing sunflower hybrids, Sunwheat 101 and MRS 34, with shorter than normal height and a narrower growth habit were grown at 30- and 60-cm row spacings and three plant densities at each row spacing in the 1986 and 1987 seasons at Morden, Manitoba. There were no differences in achene yield or oil content between row spacings. Plant height and oil content of achenes increased with increase in plant density, while achene weight decreased. Achene yield of both hybrids increased as plant density increased from 55 000 to the 74 000 plants ha−1 density, then remained relatively constant to 148 000 plants ha−1.Key words: Oilseed sunflower, Helianthus annuus L., plant row spacing, plant density

Multiple regression equations relating decortication with such achene characteristics as oil content, achene weight and density, in three sets of oilseed sunflowers were developed. Hull content and wax content were included in one set of hybrids. Good prediction of decortication could be obtained from the achene characteristics that are routinely determined, i.e., oil content, achene weight and density. Oil content was the most significant factor, followed by achene density. Key words: Decortication, sunflower

For three years, field research has been conducted in the industrial conditions to study the effectiveness of the fungicide preparation Pictor during sunflower cultivation. It has been established that spraying crops with this preparation helps to increase plant productivity and increase yield capacity of two hybrids of different maturity groups of the company “Limagrain” LG 56.63 and LG 56.54 by 5.6 and 5.7 kg/ha (+ 18.6 and 19.0% ) respectively. The use of Pictor preparation also has a positive effect on the oil content in the grown sunflower seeds. Key words: sunflower, fungicidal preparation Pictor, yield capacity, oil content of seeds.
