Breeding of Modern Rose Cultivars Decreases the Content of Important Biochemical Compounds in Rose Hips.

This study aimed to determine the content and composition of bioactive compounds in autochthonous rose hips (, , and ) and to compare them with the content of bioactive compounds in some cultivars ('Harstad', 'Bourgogne', 'Mount Everest', 'Poppius', 'Fruhlingsduft', 'Single Cherry', 'Fruhlingsmorgen', 'Violacea', and 'Splendens') derived from these main species. Due to insufficient information on how bioactive compound content changes when crossing roses, this study also sought to ascertain whether modern rose hip cultivars are still a sufficiently rich source of bioactive compounds and could, therefore, be potentially used as a functional food. All material was collected in the Arboretum Volčji Potok (Slovenia).

Detailed Metabolic Characterization of Flowers and Hips of L. Grown in Open Nature.

Our research aimed to investigate the primary and secondary metabolites of rosehips and petals of in comparison with . was chosen because it is still unexplored in terms of various bioactive substances and is strongly present in Slovenia. Given that roses are generally very variable and unstudied, our research will contribute to greater transparency and knowledge of the bioactive composition of rosehips and petals.

Phenolic Compounds of Rose Hips of Some Species and Their Hybrids Native Grown in the South-West of Slovenia during a Two-Year Period (2020-2021).

The genus is very extensive and variable, so it remains very unpredictable and uninvestigated. This also holds true for values of secondary metabolites in rose hips, which are important for several purposes (human diet, protection of plants against pests, etc.).

Characterization of the Slovene Autochthonous Rose Hybrid × ( Waldst. and Kit) Using Biochemical Patterns of the Plant Blossoms.

The genus is characterized by great variability and, consequently, they easily hybridize. The petals of , and their hybrid × , collected in western Slovenia, were included in the research. We performed morphometric analysis using keys to determine roses and genetic analysis to determine the genome size.

Essential Oil and Hydrosol Composition of Immortelle ().

The chemical composition of essential oils and hydrosols of immortelle () stems with leaves obtained by hydrodistillation was identified using gas chromatography coupled with mass spectrometry (GC-MS). One-year-old and two-year-old plants of the same immortelle population, and plants from three Croatian populations, all grown in Slovenia, were included in the study. The main compounds of essential oils of one-year-old and two-year-old plants were α-pinene, α-eudesmol, and rosifoliol.
