13. Optimization of sunflower oil bleaching parameters: using Response Surface Methodology (RSM)
Abstract Bleaching is an important part of the oil refining process, in which pigments, impurities, traces of metals, and oxidative-molecular components of oils are removed. In this regard, the optimization of bleaching conditions can be effective to increase oil quality. In this study, de-gummed and neutralized sunflower oil was bleached at 80, 90, 100, 110

14. Extension of the vase life of cut sunflower by different vase solutions
Abstract Sunflower (Helianthus annuus L.) as a cut flower has been an increasing demand in floral industry. However, its vase life is limited because of scape bending, abscission and early wilting of ray flowers. This study was conducted to evaluate the effects of different vase solutions on the vase life of cut sunflower ‘Sunrich Orange’. ‘Sunrich Ora

15. Evidence of accelerated and altered pollen development after Imazapyr treatment in resistant sunflower
ABSTRACT Imazapyr (IM) treatment applied at early reproductive developmental stages have been associated with induced male sterility in sunflower (Helianthus annuus L.). The aim of this work was to determine the effects induced by two different doses of IM-treatment (1X and 2X; 80 and 160 g a.i.·ha-1) on pollen grain yield, pollen viability and on the exine

16. Effect of heat treatment for liquefaction and pasteurization on antioxidant activity and phenolic compounds of Astragalus and sunflower-cornflower honeys
Abstract In this study, effect of heat treatments (liquefaction at 55 °C for 12 h and pasteurisation at 90 °C 15 sec) on total phenolic content, antioxidant activity and phenolic compounds of astragalus and sunflower-cornflower honeys was investigated. Total phenol content and antioxidant activity of honeys were assessed by Folin-Ciocalteu and ABTS methods

17. Use of Sunflower and Soybean as Bioindicators to Detect Atrazine Residues in Soils
RESUMO: A atrazine é seletiva para milho, cana-de-açúcar e sorgo e pode interferir em culturas sucessoras, como girassol e soja. Apesar da problemática, são poucos os estudos acerca do efeito residual desse herbicida nessas culturas. Assim, o objetivo desta pesquisa foi avaliar o efeito residual da atrazine por meio da biodisponibilidade do herbicida em

19. Saline-sodic soil treated with gypsum, organic sources and leaching for successive cultivation of sunflower and rice
RESUMO A correção de solos salinos e sódicos objetiva reduzir os sais dissolvidos na solução e sódio trocável, respectivamente, possibilitando o crescimento e a produção das culturas. Neste contexto, um experimento foi desenvolvido, entre agosto/2011 e setembro/2012, em solo salino-sódico do Perímetro Irrigado de São Gonçalo, no município de So

20. Lipid Sources in Diets for Hy-Line White Laying: Performance, Biometrics of Digestive Organs, and Bone Characteristics
ABSTRACT Dietary inclusion of lipid sources has been one of the methods adopted by nutritionists aiming at better energy balancing. However, alternative energy feedstuffs have been sought in an attempt to reduce production costs. In this regard, lipid sources that can replace conventional ones, such as beef tallow, cottonseed oil, and sunflower oil have been

21. Partial replacement of soybean meal with pea grains and sunflower cake in ewe diets: milk quality and blood biochemical parameters
ABSTRACT The objective of this research was to evaluate the effect of pea and sunflower cake as partial replacement for soybean meal in diet, as well as to assess their effect on milk quality during lactation and on blood parameters of ewes kept in organic farming. The research was carried out with 30 ewes of Merinolandschaf breed during 75 days. Ewes were g
