Abstract Resistance inducing effects of an extract of Lychnis viscaria L. seeds, containing different brassinosteroids (BR), were investigated. Application of aqueous solutions in concentrations from 0.5 to 10 mg/l (dry wt. of extract) resulted in an enhanced resistance of tobacco, cucumber and tomato to viral and fungal pathogens of up to 36% compared with water-treated control plants. No direct anti-fungal effects in mycelium growth assays with Phytophthora infestans could be observed. After treatment and inoculation with powdery mildew a stimulation of different PR-proteins (ca. + 20% for peroxidase, + 30% for chitinase and up to + 68% for β-1,3-glucanase) in cucumber was found. A chitinase in gel-electrophoresisassay showed a stronger induction of a distinct isoform under the same conditions. Time course of peroxidase induction and changes of apoplastic protein patterns revealed by SDS-PAGE indicated an earlier triggering of defence responses after plant-extract treatment and pathogen attack, probably being responsible for the increased resistance. Involvement of the brassinosteroids in the plant extract is discussed to elicit or mediate the activation of defence-mechanisms.

The last glacial deposits of the Ballaugh-Kirkmichael area in the north-east of the Isle of Man have been investigated by analysis of pollen and macroscopic fossils and by radiocarbon dating. Assemblages totalling over 160 taxa of vascular plants and mosses have been recorded from strata referred to LateWeichselian zones I, II and III. Among the most noteworthy species are 46 not now living on the island; these include Dianthus deltoides, Juncus balticus, Lychnis viscaria, Ranunculus hyperboreus, Sibbaldia procumbens, Meesia tristicha, Helodium blandowii and Polytrichum norvegicum. The vegetation comprised a great diversity of communities of open, largely calcareous grassland, snow beds, mires both base-rich and base-poor, flushes, freshwater, inundated flats and calcareous dunes. Saline conditions are indicated by Glaux maritima and Triglochin maritima . Trees were represented only by Betula and the taller shrubs by Juniperus and Salix .
