AB  - Sunflower is an important industrial crop. Together with the expansion of the production areas, the challenges in growing sunflower are becoming tougher. Undoubtedly one of the most important problems in sunflower cultivation is the parasitic plant broomrape (Orobanche cumana). The first use of wild Helianthus species for introduction of broomrape resistance dates from the first half of 20th century when Russian academician Zhdanov developed resistant sunflower genotypes from interspecific crosses with H. tuberosus, H. mollis and H. maximiliani. Taking into account the ability of broomrape to evolve into more aggressive races and thus overcome the resistance genes, scientists are forced to constantly search for new sources of resistance. As a result, sources with different levels of resistance are found in H. tuberosus, H. mollis, H. maximiliani, H. nuttalii, H. debilis, H. neglectus, H. niveus, H. argophyllus, H. divaricatus, H. bolanderi, H. petiolaris, H. praecox, H. deserticola and H. grosseserratus. Breeding for genetic resistance is even more challenging due to the existence of not only large broomrape interpopulation divergence, but also intrapopulation divergence. One of the areas that has not received enough attention is the anatomical characterization of the root of wild sunflower species and sunflower in general. It is known that pre-haustorial resistance to broomrape is determined by the development of physical barriers in host root cell walls, which prevents linkage of broomrape to the host. A detailed anatomical characterization of root in wild Helianthus species can give valuable information about differences between the species and more knowledge about the nature of resistance of certain Helianthus species to broomrape.

AB  - The aim of this research was to determine the histological basis of the genotypic differences for drought tolerance, calculate tissue volume densities (Vv), examine the variability, and assess tissue proportions along the root maturity gradient. For the stereological analyses of root tissues four sunflower genotypes, 14 days old seedlings which were grown in rhizotrons, have been carried out on the primary (axial) root. The total length of the axial roots varied among genotypes, but not significantly. Root cross-sections were cut along the root maturity in five segments according to the principle of systematic uniform random sampling method. Cross-sections were made applying cryo-technique procedure and proportion of tissues was estimated by point-counting method. The vessel network characteristics (number and diameter of vessels) vary along maturity gradient and individual roots. Consequently, branching vessels pattern and axial conductance may limit water flow through root systems.
