The wild sunflowers collection in Novi Sad
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Lowered genetic variability in the cultivated sunflower and use of interspecies hybridization in sunflower breeding were the main reasons to establish the wild species collection. Wild species were collected during collecting ...
Effect of naphthenic acids on formation of adventitious roots in sunflower cuttings
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2003)
The paper describes a study of the effect of salts of natural naphthenic acids on the rooting of young sunflower cuttings and latteral branching of interspecies sunflower hybrids. Naphthenic acids were obtained by alkaline ...
Effect of harvest date on seed viability of different sunflower genotypes
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
Effect of harvest date on seed viability has been examined in 3 different sunflower genotypes. Harvesting started 7 days after fertilization. It was done 10 times, at 3-4-day intervals. Seed moisture was determined before ...
A new association of ruderal weeds at Pančevački Rit in Serbia
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
A several-year study of distribution, phytocoenological differentiation, floristic composition and structure of ruderal flora and vegetation and relevant anthropogenic influence was conducted at Pančevački Rit in Serbia. ...
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 ...
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 maturation period on seed quality; optimum time for desiccation in sunflower (helianthus annuus l) genotypes
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2006)
To harvest a sunflower crop, it is important to bring moisture content, i.e moisture level in leaves, stems, heads and seed, to a level that permits normal work of combine harvester. In 2003, an experiment was established ...
Interpretation of interactions in sunflower agronomic trials using multiplicative models and climatic information
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
A three-year experiment (2005, 2006, 2007) including three sunflower hybrids and eight sowing dates was carried out in order to study the impact of hybrid × sowing date interaction on oil yield of sunflower hybrids. With ...
Tolerance of sunflower (Helianthus annuus L.) to imazethapyr
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2008)
The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid 'Zoltan' (S) was investigated under controlled conditions. Hybrids grown in pots were treated ...
Micropropagation of Helianthus maximiliani (Schrader) by shoot apex culture
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2001)
H. maximiliani was micropropagated using culture of shoot apices on modified Murashige and Skoog medium (DV). Further propagation of in vitro grown plants was done by culture of their nodal segments and shoot tips on the ...
