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 ...
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 ...
Seed dormancy of hybrids and parent lines of sunflower (Helianthus annuus L.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Sunflower is a plant species with a prominent period of seed dormancy. Physiological maturation period can be accelerated under laboratory conditions using methods for breaking seed dormancy such as: previous cooling at ...
The wild sunflowers collection in Novi Sad
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)

(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
The objective of this study was to analyze the variability and mutual dependence of the tuber weight per plant, tuber number per plant, average tuber weight and total sugars content in the tubers of 20 Jerusalem artichoke ...
Inheritance of increased oleic acid content in sunflower seed oil / Nasleđivanje povećanog sadržaja oleinske kiseline u ulju suncokreta
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2000)
The inheritance of increased (mid) oleic acid content about 62% of an inbred line, LG27, was studied in the crosses with high oleic HA89OL (89%), high oleic LG26OL (86%) and low oleic LG28 (22%). Fatty acid composition of ...
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 ...
Effect of morphological and physiological traits on seed yield and oil content in sunflower
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Path coefficient analysis was used to separate direct and indirect effects of studied traits on seed oil content and seed yield, and to identify traits that could be used as selection criteria in sunflower breeding. ...
