    • Automated image analysis tool to measure microbial growth on solid cultures 

      Ancin-Murguzur, Fransisco Javier; Barbero-López, Aitor; Kontunen-Soppela, Sari; Haapala, Antti (Elsevier BV, 2018)
      Microbial growth on culture media is a commonplace technique to estimate the growth rate and virulence of microbes, assess inhibitory effects of compounds and estimate potential damages of plant pathogens in agriculture. ...

    • Climate and Competitive Status Modulate the Variation in Secondary Metabolites More in Leaves Than in Fine Roots of Betula pendula 

      Tullus, Arvo; Rusalepp, Linda; Lutter, Reimo; Rosenvald, Katrin; Kaasik, Ants; Rytter, Lars; Kontunen-Soppela, Sari; Oksanen, Elina (Frontiers Media SA, 2021)
      Plant secondary metabolites have many important functions; they also determine the productivity and resilience of trees under climate change. The effects of environmental factors on secondary metabolites are much better ...

    • Genotype- and provenance-related variation in the leaf surface secondary metabolites of silver birch 

      Deepak, Maya; Lihavainen, Jenna; Keski-Saari, Sarita; Kontunen-Soppela, Sari; Salojärvi, Jarkko; Tenkanen, Antti; Heimonen, Kaisa; Oksanen, Elina; Keinänen, Markku (Canadian Science Publishing, 2018)
      The cuticular wax layer on silver birch (Betula pendula Roth) leaves is rich in cyclic secondary metabolites that provide defense against various environmental factors. Micropropagated trees from the southern (60°N), central ...

    • Plants have different strategies to defend against air pollutants 

      Oksanen, Elina; Kontunen-Soppela, Sari (Elsevier BV, 2020)
      Plants are exposed to various harmful air pollutants, which cause oxidative stress and pose a threat to plant health, agriculture production, and vitality of ecosystems. Despite the climate actions and technological ...

    • Strategy by latitude? Higher photosynthetic capacity and root mass fraction in northern than southern silver birch (Betula pendula Roth) in uniform growing conditions 

      Tenkanen, Antti; Suprun, Sergei; Oksanen, Elina; Keinänen, Markku; Keski-Saari, Sarita; Kontunen-Soppela, Sari (Oxford University Press (OUP), 2021)
      Growth of northern trees is limited by short growing seasons. In multi-year trials, northern trees usually grow less than southern ones but can have higher gas exchange, whereas differences in biomass allocation and its ...

    • Tree provenance affects the growth and bioenergy potential of juvenile silver birch 

      Haapala, Antti; Kontunen-Soppela, Sari; Oksanen, Elina; Rousi, Matti; Mola Yudego, Blas (Natural Resources Institute Finland, 2017)
      The ever-growing need for renewable resources for energy production makes us look more closely at biomass reserves so far unused and considered insufficient in terms of energy content, availability or cost. In this study ...
