Feasibility of keeping F, interspecific sunflower hybrids
(Paris : International Sunflower Association, 2012)
Helianthus genus comprises 14 annual and 37 perennial species. Perennial species reproduce vegetatively (rhizomes, tubers) so that it is relatively easy to maintain them in ex situ collections in the field. Hybrid plants ...
Bio-ecological relations of sunflower pathogens - macrophomina phaseolina and fusarium spp. And sunflower tolerance to these pathogens
(Natl Agricultural Research & Development Inst, Fundulea, 2012)
Macrophomina phaseolina, Fusarium solani and F. oxysporum are soil borne species which infect root, stem and collar region of plant host and cause cortical and vascular discoloration. There is need for identification of ...
Association between seed yield and some morphological characteristics in sunflower / Povezanost između prinosa semena i nekih morfoloških svojstava suncokreta
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Objective of this study was to determine the divergence and association between seed yield and three morphological characteristics that are very important in sunflower breeding (plant height, head diameter and days to ...
Influence of substrate, chemical treatment and length of storage on sunflower seed germination
(Paris : International Sunflower Association, 2012)
For determination of sunflower seed quality several substrates are in use: sand, soil, compost and filter paper where sand is most commonly used. Sand enables good contact of seeds and substrate and decreases possibility ...
Yttrium - accumulation, translocation and distribution in young sunflower plants (helianthus annuus l.)
(Fresenius Environmental Bulletin, 2012)
Even though yttrium (Y), similarly to the other rare earth elements, is widely present in the soils and plants, there is little experimental data describing its effects on plant growth and metabolism. Therefore, the aim ...
Resistance of some sunflower genotypes to broomrape (Orobanche cumana Warll.) and its influence on seed yield and quality
(Beograd : Institut za zaštitu bilja i životnu sredinu, 2012)
Broomrape (Orobanche cumana Wallr.) is a flowering parasitic plant which is one of the major sunflower parasites. Different sunflower hybrids have different reaction to the broomrape. The aim of this paper is to evaluate ...
Is there appearance of new broomrape race in Serbia?
(Paris : International Sunflower Association, 2012)
Broomrape in sunflower fields in Serbia has been appearing with a varying intensity almost every year. Yield losses depend on the intensity of the attack and they can range from 5 to 100 %. According to previous investigations ...
Genetic diversity of Macrophomina phaseolina isolates from different regions and host plants
(Paris : International Sunflower Association, 2012)
Macrophomina phaseolina (Tassi) Goid. is a soil borne pathogen with a wide host range which causes disease on more than 500 cultivated and wild plant species. The absence of host specificity and its geographic distribution ...
Screening perennial Helianthus species for powdery mildew
(Paris : International Sunflower Association, 2012)
Powdery mildew (Erysiphe cichoracearum) has been reported as a potential constraint for sunflower growing in regions with warm climate. Severity of disease varies depending on the sunflower genotype. Aim of this research ...
Evaluation of resistance of new sunflower hybrids to broomrape in the breeding programs in Novi Sad
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2012)
Broomrape (Orobanche cumana Wallr.) presents a serious problem in sunflower production in a number of countries, it reduces sunflower seed yield and negatively affects other sunflower traits in sunflower production. Continued ...
