Tuhkan vaikutuksia siementen it\u00e4vyyteen ja taimien kasvuun testattiin sek\u00e4 laboratoriossa kasvatuskaapissa ett\u00e4 ulkona kasvatusastioissa. Kasvatusalustan pH s\u00e4\u00e4dettiin turpeen avulla. Lupiinin lis\u00e4ksi k\u00e4sittelyt tehtiin kolmelle verrokkilajille, punanadalle (Festuca rubra), valkoapilalle (Trifolium repens) sek\u00e4 m\u00e4kitervakolle (Silene viscaria).

The large-leaved lupine (Lupinus polyphyllus) is considered invasive in Finland because the species displaces native flora where it grows and is difficult to remove. The effect is seen in the whole community. Many of the displaced species are endangered. Previous studies have suggested that alkaline soil is not suitable for lupine. This study aimed to determine whether wood ash could raise the substrate alkalinity to a level that would prevent lupine growth and whether road verges could be treated with granulated ash in order to remove lupine permanently. The effects of ash on seed germination and seedling growth were examined both in a growth chamber in laboratory conditions and in plant pots outdoors. The alkalinity was adjusted with peat. Along with lupine, three native species were tested as comparators: red fescue (Festuca rubra), white clover (Trifolium repens) and sticky catchfly (Silene viscaria). In laboratory conditions both the ash and the peat affected the lupine adversely. The ash hindered red fescue germination and emergence of the cotyledons of all the studied species. It also lowered the fresh weight of the treated lupine seedlings but didn\u2019t affect their dry weight. The experiments outdoors showed that the granulated ash didn\u2019t raise the soil pH nor did it affect lupine germination or growth. It did, however, fertilize the fescue. The results of the laboratory experiments could not be reproduced outdoors even when using a large amount of ash, suggesting that treating road verges with granulated ash would not prevent lupine growth, but might instead fertilize the lupines. The experiments in the growth chamber also indicate that using ash treatment to raise the pH might weaken the lupine but would also complicate covering the road verges with native species.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2020-06-03T12:37:41Z\r\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-06-03T12:37:41Z (GMT).
