Effect of time of desiccation on oil content in different sunflower hybrids
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2001)
Chemical desiccation with Reglone Forte has been tried in production fields under four sunflower hybrids. Reglone Forte (2 l/ha) was applied at 7-day intervals from the end of pollination till maturity. Seed moisture was ...
Planting date effects on oil yield in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Oil yield per unit area is the ultimate target in growing high-oil sunflower genotypes. A research was carried out to determine planting date effects on oil yield, using three sunflower hybrids (Miro, Rimi, Pobednik), eight ...
Influence of aging process on biochemical changes in sunflower seed
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2005)
This investigation was conducted in order to determine the degree of biochemical changes during accelerated and natural aging of sunflower seed. Five sunflower lines developed in Novi Sad, submitted to accelerated aging ...
Heterosis for agronomically important traits in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Significant manifestation of heterosis for agronomically important traits is the main precondition for obtaining productive sunflower hybrids (Škorić et al., 2006). Development of high-yielding and stable sunflower hybrids ...
Effect of water stress on yield and evapotranspiration of sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2009)
An experiment was conducted at Rimski Šančevi Experiment Field of Institute of Field and Vegetable Crops in Novi Sad during 2000 - 2005. The soil in the experimental plot was calcareous chernozem on loess terrace. Using ...
An analysis of heterotic potential for agronomically important traits in sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Study of inbreeding and heterosis in sunflower has been taking place for over 80 years now. Practical application of the phenomenon of heterosis in this species began after the discovery of a suitable source of cytoplasmic ...
Transferring Plasmopara halstedii resistance from annual wild into cultivated sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Twenty-nine populations of five wild annual sunflower species (H. annuus, H. petiolaris, H. argophyllus, H. praecox, H. debilis and H. neglectus) were screened for resistance to Plasmopara halstedii by the whole seed ...
Use of oxalic acid for screening intact sunflower plants for resistance to Sclerotinia in vitro
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2002)
Three sunflower inbred lines differing in resistance to Sclerotinia were grown on nutritive medium supplemented with different concentrations of oxalic acid. After two weeks of culture, plant height, fresh and dry weight ...
Biochemical characteristics and nutrient content of the callus of sunflower inbred lines
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2004)
Mineral nutrition is a factor affecting in vitro regeneration. Various requirements for individual mineral elements between plant species and also between genotypes of the same species have led to the differentiation and ...
Changes of fatty acids content and vigor of sunflower seed during natural aging
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2007)
Sunflower seed aging during storage affects seed vigor and content of fatty acids. In order to reveal severity of their influence, the following vigor tests were applied: standard laboratory germination test, cold test and ...
