IVANOVA, P., V. CHALOVA, L. KOLEVA, I. PISHTIYSKI and M. PERIFANOVA – NEMSKA, 2012. Optimization of protein extraction from sunflower meal produced in Bulgaria. Bulg. J. Agric. Sci., 18: 153-160 Sunflower meal obtained after defatting of sunflower seeds is a by-product, which has the potential to serve as an attractive source for the preparation of protein isolates for food purposes. Protein ex...

Identifying the best inbred combinations for the development of commercial hybrid of sunflower remains the main challenge to sunflower breeders. In the present research the level of heterosis of F1 hybrids, genetic diversity of parental lines based on SSR markers, as well as its connection with specific combining ability of sunflower were studied. Ten sunflower elite inbred lines (3 restorer li...

Sunflower (Helianthus annuus L.) oil remains under-utilised albeit one of the major seed oils produced world-wide. Moreover, the high oleic sunflower varieties make the oil attractive for applications requiring high temperature processes and those targeting the C=C double bond functionality. Herein an overview of the recent developments in olefin metathesis of sunflower-based feedstocks is pres...

The biology and behavior of the longhorned beetle Dectes texanus LeConte (Coleoptera: Cerambycidae) was studied on two host plants that suffer economic losses from this pest; sunflower, Helianthus annuus, and soybean, Glycines max. Reciprocal crosses of D. texanus collected from the two plants all produced viable progeny, indicating that conspecific insects attack both crops. Pupae from soybean...

Lentz et al. (1) cite linguistic evidence supporting their hypothesis that Helianthus annuus was domesticated in Mesoamerica in pre-Columbian times. This consists, in part, of a list of names for sunflower collected from speakers of 14 contemporary native languages. They conclude that the fact that terms for sunflower in 11 of these languages do not phonologically resemble Spanish words for sun...

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 2×5 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. D...

Genetic analyses of the domestication syndrome have revealed that domestication-related traits typically have a very similar genetic architecture across most crops, being conditioned by a small number of quantitative trait loci (QTL), each with a relatively large effect on the phenotype. To date, the domestication of sunflower (Helianthus annuus L.) stands as the only counterexample to this pat...

Sunflower is an important oilseed crop, however the genetic transformation of sunflower has been very challenging to date. In the present study, we describe a successful Agrobacterium-mediated transformation approach via somatic embryogenesis from immature zygotic embryos of sunflower. By optimizing the culture medium, we have achieved high efficiency (45.5%) of somatic embryogenesis with MS me...

From late July to early November 1979, 1980, and 1982, red-winged blackbirds were collected in sunflower, field corn, and at two roosts in Cass County, North Dakota. Their espophageal contents were examined, and they were also assessed for stage of molt. Both males and females contained a higher proportion of sunflower in sunflower fields than corn in field corn (P < 0.05). Male redwings consum...

BACKGROUND Regardless of the overall association between diet and acne which cannot be easily ignored, there might be an association between specific nutrients and acne development or improvement. OBJECTIVES The aim of this study was to assess the effect of dietary intake of sunflower seeds on acne severity and the pattern of acne lesions. PATIENTS AND METHODS In a randomized controlled tri...
