Greenhouse test for the resistance to root and stem rot of Hypericum perforatum L. accessions

Root and stem rot caused by soil-borne agent Fusarium avenaceum is a major disease of wild Hypericum perforatum accessions in the field collection of Medicinal and Aromatic Plants (MAP) of the Institute of Botany in Lithuania. These wild accessions of H. perforatum are growing as an initial material for breeding. In 1998–2001 the monitoring of epidemiological situation of field collection of H. perforatum showed differences among accessions considering the resistance to root rot. High intensity of root rot was observed in the third–fourth years of cultivation. The most damaged plants (> 50%) were among the accessions 219, 379, 381, and cv. Zolotodolinskaja. Fungi of the Aspergillus, Cladosporium, Penicillium, Rhizoctonia, and Verticillium genera were associated with H. perforatum roots together with the rot agent Fusarium avenaceum. Seven accessions from Lithuania and cv. Zolotodolinskaja of H. perforatum were tested for the resistance to root rot under greenhouse conditions. Two accessions (219, 381) were highly susceptible to the disease, another two (218, 383) were less susceptible, others were free of the symptoms of root rot. Accessions and single plants, survived after artificial infection, have been selected for further investigations.

Abstract This work refers to the native species of genus Astragalus L. (A. dasyanthus, A. ponticus), Adonis L. (A. vernalis, A. wolgensis) and Digitalis L. (D. lanata, D. grandiflora). The plants are cultivated in the Botanical Garden of Moldova in the field collection of the medicinal and aromatic plants. Investigation includes propagation aspects, research into cultivation techniques and conservation measures. The biological particularities and the phenologic rhythm are also registered. The obtained data shows the ecological flexibility of species and the possibility of preserving them in culture.

Field Collection

AbstractMorphological, reproductive and karyological variability were investigated in fifteen populations of Allium oleraceum transferred from natural populations in Lithuania to the field collection of medicinal and aromatic plants of the Institute of Botany of the Nature Research Centre in Vilnius. Nine populations were tetraploid (2n = 4x = 32), four pentaploid (2n = 5x = 40) and two consisted of both cytotypes. The greatest differences among the populations and between the ploidy levels were observed in stem height and mass of aerial bulbils per plant. The seed production was very low and did not differ significantly between the ploidy levels, while neither tetraploids nor pentaploids did produce any seed if insects were prevented from visiting their flowers. The means of the morphological characters were higher in pentaploids than in tetraploids. However, none of them provided the possibility of determining ploidy level without chromosome counting.
