Dynamics of fine-root production and mortality of Scots pine in waterlogged peat soil during the growing season
Autor: Tapani Repo, Sirpa Piirainen, Tarja Lehto, Raimo Silvennoinen, Timo Domisch, Jouni Kilpeläinen
Publikováno v: Canadian Journal of Forest Research. 50:510-518
Excess water in the rooting zone critically reduces tree growth and may even kill trees; however, the relative importance of damage to roots versus aboveground parts and the time course of damage are not well understood. We studied the dynamics of fi

Future climate scenarios for the boreal zone project increasing temperatures and precipitation, as well as extreme weather events such as heavy rain during the growing season. This can result in more frequent short-term waterlogging (WL) leading to u

Are arbuscular-mycorrhizal Alnus incana seedlings more resistant to drought than ectomycorrhizal and nonmycorrhizal ones?
Autor: Jouni Kilpeläinen, Tarja Lehto, Sammi Alam Nipu, Bartosz Adamczyk, Pedro J. Aphalo, Aitor Barbero-López
Publikováno v: Tree Physiology. 40:782-795
Arbuscular mycorrhizas (AMs) prevail in warm and dry climates and ectomycorrhizas (EMs) in cold and humid climates. We suggest that the fungal symbionts benefit their host plants especially in the corresponding conditions. The hypothesis tested was t

Separating the effects of air and soil temperature on silver birch. Part II. The relation of physiology and leaf anatomy to growth dynamics
Autor: Jouni Kilpeläinen, Timo Domisch, Tarja Lehto, Minna Kivimäenpää, Françoise Martz, Sirpa Piirainen, Tapani Repo
Publikováno v: Tree physiology. 42(12)
The aboveground parts of boreal forest trees grow earlier in the growing season, the roots mostly later. The idea was to examine whether root growth followed soil temperature, or whether shoot growth also demanded most resources in the early growing

Separating the effects of air and soil temperature on silver birch. Part I. Does soil temperature or resource competition determine the timing of root growth?
Autor: Jouni Kilpeläinen, Timo Domisch, Tarja Lehto, Sirpa Piirainen, Raimo Silvennoinen, Tapani Repo
Publikováno v: Tree physiology. 42(12)
The aboveground parts of boreal forest trees mostly grow earlier, and the roots later, in the growing season. We aimed to experimentally test whether the extrinsic driver of soil temperature or the intrinsic driver (resource competition between plant

Root and shoot phenology and root longevity of Norway spruce saplings grown at different soil temperatures
Autor: Ilkka Leinonen, Jouni Kilpeläinen, Leena Finér, Tapani Repo, Aija Ryyppö, Tarja Lehto, Pedro J. Aphalo, Timo Domisch
Publikováno v: Canadian Journal of Forest Research. 49:1441-1452
Tree roots comprise a huge carbon pool. Their dynamics are driven by environmental factors and thereby affected by climate change. We studied the effects of soil temperature on root and shoot phenology and their linkages in Norway spruce (Picea abies

Waterlogging and soil freezing during dormancy affected root and shoot phenology and growth of Scots pine saplings
Autor: Sirkka Sutinen, Tarja Lehto, Ai-Fang Wang, Marja Roitto, Tapani Repo, Timo Domisch
Publikováno v: Tree Physiology. 39:805-818
Soil waterlogging is predicted to increase in the future climate in boreal regions due to increased precipitation. Snowmelt periods in winter may also become more common and further increase the amount of water in soil. It is not well known how water

Morphological and ecophysiological root and leaf traits in ectomycorrhizal, arbuscular-mycorrhizal and non-mycorrhizal Alnus incana seedlings
Autor: Jouni Kilpeläinen, Tarja Lehto, Pedro J. Aphalo, Aitor Barbero-López, Bartosz Adamczyk
Publikováno v: Plant and Soil. 436:283-297
Background and aims The aim was to assess possible benefits or drawbacks of arbuscular-mycorrhizal (AM) and ectomycorrhizal (EM) colonisation compared to no mycorrhizas (NM) in seedlings of the same host species. Eight broadleaf species were tested f
