Mostly parks and forest are the most important ‘green islands’ in urban ecological network. Urban forests are belong to green areas and collected many plant species. The main aim of the article was characteristic of ancient plant species in urban forests in Tarnów. The field studies were carried out in years 2011–2012. It covered 80 phytosociological records on the area 500 m2 in herb layer of urban forests and in forest nature on oak-hornbeam. The results showed that many ancient plant species were growing in urban forest but less than in nature reserves.

Kernels of ancient hulled wheat species, Triticum monococcum, T. dicoccon, T. spelta, and threshable wheat species, T. polonicum, T. turanicum ('Kamut®'), were studied. Fusarium culmorum-infected kernels, classified as FDKs (Fusarium damaged kernels), were smaller, shrunken, wrinkled and lighter in colour than healthy kernels. The seed coats of the former were usually damaged, and white or pinkish-white mycelium formed on their surface. FDKs showed different fungal infection levels. Characteristic structural changes were noted in endosperm cells, including loosely arranged starch granules, a partial or even complete absence of the protein matrix enveloping starch granules, the disappearance of small starch granules and the presence of damaged large starch granules. The lowest degree of damage was observed in emmer and spelt kernels.
