T\u00e4ten siemenpankin avulla tapahtuva levitt\u00e4ytyminen voi k\u00e4ynnisty\u00e4, kun\nit\u00e4miseen ja taimien kasvuun vaikuttavat tekij\u00e4t kohtaavat. Pro gradu -tutkimuksessamme\nselvitimme laajalle levinneen vieraslajin, komealupiinin (Lupinus polyphyllus)\nlevitt\u00e4ytymiskyky\u00e4 ja kuinka liikenne vaikuttaa siihen. Lis\u00e4ksi tutkimme, kuinka maaper\u00e4n pH tai kasvuymp\u00e4rist\u00f6n valoisuus vaikuttavat lupiinin kasvuun ja siten sen kykyyn p\u00e4\u00e4st\u00e4 uusille alueille. Toteutimme maastotutkimuksemme Keski-Suomessa maanteiden ja py\u00f6r\u00e4teiden varrella kev\u00e4\u00e4ll\u00e4 ja kes\u00e4ll\u00e4 2011. Tutkimme lupiinin levitt\u00e4ytymist\u00e4 25 tutkimusalueella, joista ker\u00e4ttiin siemeni\u00e4 eri et\u00e4isyyksilt\u00e4 p\u00e4\u00e4esiintym\u00e4st\u00e4. Ensimm\u00e4inen ruutu (50*50 cm2) sijaitsi esiintym\u00e4n keskell\u00e4, kaksi reunoilla ja kolme et\u00e4isyyksill\u00e4 (2 m,5 m ja 10 m) molempiin suuntiin esiintym\u00e4n reunoista. Lis\u00e4ksi kontrollialueena toimi 6 lupiinitonta aluetta (3 ruutua (50*50 cm2), 10 m:n et\u00e4isyydell\u00e4 toisistaan). Mittasimme tutkimus- ja kontrollialueilla maaper\u00e4n pH:n testataksemme voisivatko erot alueiden v\u00e4lill\u00e4 selitt\u00e4\u00e4 lupiinin esiintymiseroja. pH oli kuitenkin sama kaikilla alueilla. Kasvatuskokeessa\ntestasimme, kuinka valo ja kasvualusta vaikuttavat lupiinin kasvuun. Lupiinin taimia (n = 80) kasvatettiin 2 eri kasvualustalla (multa, turve) 2 eri pH:ssa (multa: 6.5, 7.6; turve: 4,7.4) joko varjossa tai valossa 58 vuorokautta. Havaitsimme tutkimuksessamme, ett\u00e4 suurin osa siemenist\u00e4 oli esiintym\u00e4n keskell\u00e4 ja reunoilla ja levitt\u00e4ytyi vain noin 2 metrin p\u00e4\u00e4h\u00e4n. Liikenne tai siementen paino ei vaikuttanut levitt\u00e4ytymissuuntaan eik\u00e4 -et\u00e4isyyteen. Kasvatuskokeessamme lupiinin taimet kasvoivat parhaiten mullassa (pH 6.5) ja huonoiten turpeessa (pH 4). pH:ssa 6,5 (multa) kasvaneet taimet olivat pidempi\u00e4 ja painavampia sek\u00e4 niiden lehdet olivat isompia ja niit\u00e4 oli enemm\u00e4n valossa kuin varjossa kasvaneilla taimilla. Sen sijaan pH:ssa 4 (turve) kasvaneet taimet olivat lyhyempi\u00e4 ja lehdet olivat pienempi\u00e4 valossa kuin varjossa kasvaneilla taimilla. Valon m\u00e4\u00e4r\u00e4 ei vaikuttanut pH:ssa 4 kasvaneiden taimien painoon eik\u00e4 lehtien m\u00e4\u00e4r\u00e4\u00e4n. Parhaan kasvualustan pH oli 6.5 (multa), mik\u00e4 vastasi hyvin teiden varsien maaper\u00e4n pH:ta. Tutkimuksemme perusteella lupiinin levitt\u00e4ytymist\u00e4 voivat kuitenkin rajoittaa sek\u00e4 eritt\u00e4in hapan ett\u00e4 em\u00e4ksinen\nmaaper\u00e4, varjoisa ymp\u00e4rist\u00f6 ja lupiinin lyhyt levitt\u00e4ytymiset\u00e4isyys.
