Alternaria helianthi and two unreported species of Alternaria in Korea were isolated from lesions of Alternaria leaf spot disease of sunflower. The unrecorded species of Alternaria were identified as A. helianthinficients and A. protenta based on the morphological characteristics of conidiophores and conidia. A. helianthi was the dominant species, although all the three species were associated with the disease. A. helianthi, A. helianthinficiens and A. protenta produced similar symptoms on detached sunflower leaves. This is the first report of A. helianthinficiens and A. protenta pathogenic on sunflower in Korea.

해바라기씨 단백질에서 plastein을 합성 이용하기 위해 먼저 해바라기씨를 pepsin을 이용해 가수분해하는 최적 조건과, plastein을 합성하는 최적 조건을 구하였다. 최적 가수분해 조건은 pH 1.5, $45^{\circ}C$, 2% 기질농도와 2% pepsin 농도에서 24시간 반응시키는 것이었고 plastein 합성의 최적조건은 기질농도 50%, pH 4.5, $50^{\circ}C$, 0.25% pepsin 농도에서 18시간 반응시키는 것이었다. Plastein의 생성을 확인하기 위해 thin layer chromatography를 실시한 결과 해바라기씨 농축가수분해물의 TLC pattern과 plastein의 TLC pattern이 하나의 spot를 제외하고는 다르게 나타났는데 이는 plastein과 기질이 다른 것임을 표시하는 것이었다.

The reliability of power transmission and distribution depends up on the consistency of insulation in the high voltage power transformer. In recent times, considering the drawbacks of conventional mineral oils such as poor biodegradability and poor fire safety level, several research works are being carried out on natural ester based nanofluids. Earlier research works show that sunflower oil has similar dielectric characteristics compared with mineral oil. BIOTEMP oil which is now commercially available in the market for transformers is based on sunflower oil. Addition of nanofillers in the base oil improves the dielectric characteristics of liquid insulation. Only few results are available in the literature about the insulation characteristics of nano modified natural esters. Hence understanding the influence of addition of nanofillers in the dielectric properties of sunflower oil and collecting the database is important. Considering these facts, present work contributes to investigate the important characteristics such as partial discharge, lightning impulse, breakdown strength, tandelta, volume resistivity, viscosity and thermal characteristics of $SiO_2$ nano modified sunflower oil with different wt% concentration of nano filler material varied from 0.01wt% to 0.1wt%. From the obtained results, nano modified sunflower oil shows better performance than virgin sunflower oil and hence it may be a suitable candidate for power transformer applications.

In crop breeding program, information about genetic dissimilarity on breeding resources is very important to corroborate genealogical relationships and to predict the most heterozygotic hybrid combinations and inbred breeding. This study aimed to evaluate the genetic variation in Kenyan sunflower breeding lines based on simple sequence repeat (SSR). A total of 83 alleles were detected at 32 SSR loci. The allele number per locus ranged from 2 to 7 with an average of 2.7 alleles per locus detected from the 24 sunflower accessions and the average value of polymorphic information contents (PIC) were 0.384. A cluster analysis based on the genetic similarity coefficients was conducted and the 24 sunflower breeding resources were classified into three groups. The principal coordinates (PCoA) revealed 34% and 13.38% respectively, and 47.38% of total variation. It was found that the genetic diversity within the Kenyan sunflower breeding resources was narrower than that in other sunflower germplasm resources, suggesting the importance and feasibility of introducing elite genotypes from different origins for selection of breeding lines with broader genetic base in Kenyan sunflower breeding program.

Two experiments were conducted to determine the ileal digestibility of the amino acids contained in sunflower meal using the regression technique and then applying the values obtained, in a growth trial, using growing-finishing pigs. For the digestibility trial, four 20 kg crossbred ($Yorkshire{\times}Landrace{\times}Beijing$ Black) barrows were fitted with simple Tcannula in the terminal ileum. After recovery, the barrows were fed one of four experimental diets according to a $4{\times}4$ Latin Square design. The pigs were fed corn-soybean meal based diets supplemented with 0, 25, 50 or 75% sunflower meal. For the growth trial, 80 crossbred ($Yorkshire{\times}Landrace{\times}Beijing$ Black) growing pigs (21.5 kg) were fed corn-soybean meal diets supplemented with 0, 5, 10 or 15% sunflower meal. Five pens (2 gilts and 2 castrates) were assigned to each treatment. With the exception of arginine and valine, the digestibility coefficients for the indispensible amino acids declined as the level of sunflower meal in the diet increased. During both the growing (21.5-49.1 kg) and finishing (49.1-90.3 kg) periods and over the entire experiment (21.5-90.3 kg), average daily gain declined in a linear manner (p<0.05) with increasing amounts of sunflower meal. Feed intake was not significantly altered while feed conversion declined in a linear manner (p<0.05) during the grower period only. When the entire experimental period was taken into account, there would appear to be little penalty in either growth or feed conversion for including sunflower meal at levels up to 10% of the diet. Therefore, the price relationship between sunflower meal and other high-protein feedstuffs may provide an excellant opportunity for pork producers to use sunflower meal in order to reduce feed costs.

A series of four experiments was conducted to compare nutritional values of decorticated sunflower meals against soybean meal, in diets for pigs from weaning (Exp. 1 and 2) to finishing (Exp. 3 and 4). All experimental diets were prepared compensating for the energy content by using vegetable oil and the lysine content was matched using synthetic L-Lysine HCl. Twenty-one day old pigs were fed either corn-soybean meal based diet (CSBM) or corn- twice-decorticated sunflower meal based diet (CDSM) for four weeks (Exp. 1). There was no difference in performances between treatment groups. In Exp. 2, corn-non-decorticated sunflower meal based diet (CNSM) was added to the existing two treatments. Twenty-one day old pigs were fed three experimental diets for four weeks. Pigs fed CNSM had a lower weight gain and feed intake than other treatments (p<0.05). There was no difference between pigs fed CSBM and CDSM (Exp. 2). Growth performance of growing pigs was also greater (p<0.05) in pigs fed corn starch-twice- decorticated sunflower meal based diet (CSDSM) than pigs fed corn starch-non-decorticated sunflower meal based diet (CSNSM) during the eight week feeding trial (Exp. 3). There was no difference between pig fed corn starch-soybean meal based diet (CSSBM) and CSDSM (Exp. 3). In Exp. 4, growing pigs were fed three experimental diets (CSBM, CDSM, and barley-twice- decorticated sunflower meal based diet; BDSM) until the slaughter. There was no difference in growth performance of pigs during growing and finishing periods among treatments. However, pigs fed CSBM had a higher carcass dressing percentage (p<0.05) than pigs fed CDSM and BDSM. Pigs fed BDSM diet had a lower fat tissue percentage than other groups (p<0.05). The twice-decorticated sunflower meal can be used as a substitute for soybean meal in pig diets. The performances of piglets and growing-finishing pigs were not affected when soybean meal was replaced by twice-decorticated sunflower meal. This substitution needs the contribution of synthetic lysine and vegetable oil as sources of complementary nutrients to match the nutrient profile.

Objective: This study was to evaluate the sunflower cake and enzymatic complex fed to broilers from 22 to 42 d of age. Methods: In a completely randomized design, a total of 850 birds were allotted in a $2{\times}5$ factorial scheme (with and without enzymatic complex) and five inclusion levels (0%, 5%, 10%, 15%, 20%) of sunflower cake. There were 5 replications and 17 birds in each experimental unit. Data from performance, carcass yield and intestinal morphology were evaluated. Results: Feed intake, weight gain, final weight and feed:gain ratio linearly worsened as sunflower cake increased. For weight gain, final weight and feed:gain ratio, the birds whose diets contained levels of 15% and 20% of sunflower cake showed worse values (p<0.05) than the birds fed the control diet. When fed the enzymatic complex, birds improved (p<0.05) crypt depth and villus:crypt ratio in the jejunum. As inclusion levels of sunflower cake increased, villus depth and villus:crypt ratio in duodenum, jejunum and ileum linearly reduced and the crypt depth linearly increased. Carcass yield linearly reduced as sunflower cake increased. Conclusion: Based on performance, sunflower cake can be used up to 10% in broilers feeding from 21 to 42 days of age.
