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 ...
Genetic purity of sunflower hybrids determined on the basis of isozymes and seed storage proteins
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
Maintenance of genetic uniformity of lines and hybrids is a prerequisite for successful production and placement of commercial hybrid seed on the market. Genetic purity of seed as specific seed trait is of great significance ...
Development of sunflower genotypes resistant to downy mildew
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Sunflower is attacked by more than 40 different diseases of which only a certain number causes serious reduction of seed yield. One of the most damaging diseases is downy mildew, which is caused by the fungus Plasmopara ...
Classification of Jerusalem artichoke accessions by linear discriminant analysis of mineral concentration in tubers and leaves
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
Linear discriminant analysis (LDA) was used to classify 138 accessions of Jerusalem artichoke (Helianthus tuberosus L.). The analysis was performed using mineral element concentrations of tubers and leaves for N, P, Ca, ...
Seed viability of oil crops depending on storage conditions
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Changes occurring in seed during aging are significant as far as seed quality and longevity are concerned and are a consequence of the effects of different storage conditions. The chemical composition of seed with high oil ...
Radiosensitivity of sunflower inbred lines to mutagenesis
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
For much of the past century, mutagenesis has gained popularity in plant genetics research as a means of inducing novel genetic variation. Induced mutations have been applied for the past 40 years to produce mutant cultivars ...
Broomrape seed germination on nutritive media and possibility of its biological control
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
In tests of sunflower hybrids' susceptibility to broomrape under artificial inoculation conditions, a high germination rate of broomrape seed used for infestation is prerequisite. On the other hand, one of the ways to ...
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 ...
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 ...
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 ...
