AB  - Although the anatomy of the sunflower achene has been extensively studied, not enough attention is given to the research of the pericarp characteristics as potentially important parameters in the breeding programme. Therefore, we considered that it was important to make very detail comparative analysis of morpho-anatomical characteristics of achene as well as miromorphological and n-alkane characteristics of epicuticular wax of the 18 wild perennial Helianthus species. For anatomical analyses cross-sections were obtained from the middle part of pericarp using cryotechnique procedure. Micromorphological observation, morphological and anatomical analysis of pericarp were performed using Light and Scanning Electron Microscopy. The composition of the epicuticular n-alkanes was characterized by GC-FID and GC/MS analyses. Results showed differences in the distribution of phytomelanin pigment among the species. Denser phytomelanin network in the species H. salicifolius, H. resinous, H. tuberosus, and H. hirsutus may be connected with better resistance to insects and mechanical damages. Species H. resinosus, H. giganteus, and H. hirsutus are characterized by the highest percentage of cuticle and sclerenchyma thickness in the pericarp which can be a predictor of mechanical resistance to biotic and abiotic factors. Species H. strumosus, H. maximiliani, and H. grosseserratus are characterized with thin pericarp, poorly developed cuticle and epicuticle wax, as well as thin sclerenchyma tissue. In the pericarp waxes, C29 was the dominant alkane but several samples had n-alkanes longer than C33. These long-chain n-alkanes may be related to drought tolerance in some species. Obtained results of pericarp characteristics can be useful for improving technical and technological properties of the achene as well as for preservation of collection of wild sunflower species.

AB  - Phyllaries or involucral bracts surround capitulum of Helianthus L. species, play an important role in dispersion, pollination, seed germination and may protect the inflorescences against predators and negative effects of environmental factors. The aim of this research was to conduct comparative micromorphological and anatomical analyses of phyllaries of 19 wild perennial Helianthus species. Plant material was hand-collected at the time of physiological maturity. For anatomical analyses cross-sections were obtained from the middle part of the phyllaries using cryotechnique procedure. Micromorphological observation, morphological and histological measurements of phyllaries were performed using light and scanning electron microscopy (SEM). Phyllaries are arranged in three or four circles. The analyzed species showed significant differences in the size of outer phyllary leaves.

AB  - The production of high yielding cultivated sunflower genotypes, which are of higher and improved quality, as well as of increased resistance to abiotic and biotic factors, has been the main goal in the process of breeding. Apart from the taxonomically useful information, the characteristics of pericarp are very important in defining the fruit yield potential. General anatomy of the sunflower fruit is relatively well known, but not enough attention has been given to the research of the anatomic characteristics of the pericarp as potentially important parameters in the breeding programme. Therefore, we considered that it was important to make very detailed comparative analysis of pericarp anatomic characteristics of the 19 wild perennial Helianthus species. The plant material was cultivated in the experimental field. For anatomical observation mature achenes were randomly selected and cross sections were obtained from the middle part of the fruit, using cryotechnic procedure.
