Abstract

We have studied how callus cultures from two clones of Norway spruce influence the growth of two pathogens, Ceratocystis polonica and Heterobasidion annosum, when co-cultivated in vitro. In field experiments, trees of clone 409 were susceptible to both fungi, whereas clone 589 was less affected. Callus was cultured on medium containing cytokinins (benzylaminopurine, kinetin) and with or without auxin (2,4-dichlorphenoxy acetic acid). For co-cultivation with fungus, one piece of callus was placed towards the edge of each Petri dish. One and 14 days after inoculation with callus the dishes were co-inoculated with the fungus. Both clones strongly stimulated the initial growth of both fungi. Clone 589 inhibited the growth of both fungi when the fungi were inoculated one day after the callus. When the callus was cultured on medium without auxin for 14 days before co-inoculation clone 589 strongly inhibited the growth of both fungi, whereas clone 409 inhibited H. annosum only.

Abstract

Mørkerespirasjonen i veksande skot av gran (Picea abies) er funnen å samsvara godt med den daglege lengdeveksten. Liknande er funnen i bladskiver av bjørk (Betula pubescens) og alm (Ulmus glabra). Dei årlege akkumulerte respirasjonssummane viste korrelasjon med utbreiingsgrensene for desse treslaga. Det har blitt gjort utrekningar av kva konsekvensar ein mogeleg auke i sommartemperaturen vil få. Over tid vil høgdegrensene for dei to treslaga stiga med opptil 400 meter. Forsøk med bjørk har vist at dette treslaget har stor evne til å tilpassa seg temperaturendringar ved hjelp av ulike kompensasjonsmekanismar.

Abstract

Forsøk viser at mørkerespirasjonen i veksande skot av norsk gran (Picea abies (L.)Karst.) har samanheng med den daglege veksten. Liknande samanhengar er funne i bladskiver av bjørk (Betula pubescens Ehrh.) og alm (Ulmus glabra var. scabra Huds.). Årleg akkumulert respirasjon viser korrelasjon med utbreiingsgrensene til desse treslaga. Det er venta at klimaendringa på langt sikt vil føra til at tregrensene for dei undersøkte treslaga vil stiga med 400 m. Forsøk med bjørk viser at dette treslaget har eit stort potensial for temperaturtilpassing ved ulike kompensasjonsmekanismar.
