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 ...
Yield component analysis and diversity in Jerusalem artichoke (Helianthus tuberosus L.)
(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 ...
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 ...
Exploring environmental determinants of the geographic distribution of broomrape (Orobanche cumana Wallr.)
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Broomrape is one of the most critical biotic constraints to sunflower crop production. In the most extended sunflower crop area of the world, distributed across Black sea region, this parasitic weed shows a high occurrence. ...
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, ...
Effect of silicon on sunflower growth and nutrient accumulation under low boron supply
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2013)
Study was focused on effect of silicon (Si) on growth and nutritional status of sunflower (Helianthus annuus L.) under low boron (B) external supply. Plants were grown under controlled environmental conditions in nutrient ...
Non-parametric stability analysis of sunflower oil yield trials
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
A three-year experiment (2008, 2009, 2010) on twenty sunflower hybrids grown in 13 (2010) to 15 (2009, 2008) locations in the region of Vojvodina and central Serbia was carried out in order to study GEI (genotype × environment ...
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 ...
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 ...
Screening wild sunflower species and F1 interspecific hybrids for resistance to broomrape
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Broomrape has become one of the most important threats to the cultivated sunflower. New sources of resistance genes are needed to maintain sunflower production. The objective of this research was to evaluate accessions of ...
