Fine Roots Of Aspen Clones In High Salt And Petroleum Hydrocarbon Pollution, Kim Yrjälä, Ivika Ostonen, Shinjini Mukherjee, Timo Sipila, Lu-Min Vaario, Pertti Pulkkinen Dec 2011

Fine Roots Of Aspen Clones In High Salt And Petroleum Hydrocarbon Pollution, Kim Yrjälä, Ivika Ostonen, Shinjini Mukherjee, Timo Sipila, Lu-Min Vaario, Pertti Pulkkinen

Aspen Bibliography

The quality of polluted soil can much be improved and the environmental risks reduced by use of phytoremediation. Harmful hydrocarbon compounds can be degraded through the activity of plant and its associated microbes. We previously showed that PAHs increase aromatic ring-cleavage gene diversity in rhizosphere of birch (Sipilä et al. 2008, Yrjälä et al. 2010a) and the rhizosphere of aspen harbors Burkholderia bacteria able to degrade aromatics (Yrjälä et al. 2010b). The results are promising for successful remediation of polluted soils with woody plants. The aim of our studies is to elucidate the response of the plant and the associated …

Leaf Number Indicates Salt Tolerance Of Young Seedling Families Of European Aspen (Populus Tremula L.) Growing In Different Soils, Lu-Min Vaario, Kim Yrjälä, Matti Rousi, Timo Sipila, Pertti Pulkkinen Mar 2011

Leaf Number Indicates Salt Tolerance Of Young Seedling Families Of European Aspen (Populus Tremula L.) Growing In Different Soils, Lu-Min Vaario, Kim Yrjälä, Matti Rousi, Timo Sipila, Pertti Pulkkinen

Aspen Bibliography

Soil salinity limits plant productivity and quality. We evaluated the response of 12 aspen (Populus tremula) families to salt stress in two different soils irrigated for 4-weeks with 0, 80 or 160 mM saline solution. Easily measurable characteristics such as shoot height, leaf number, dry mass as well as the distribution of sodium (Na+) ions were measured in 5-month-old aspen seedlings raised in controlled greenhouse conditions on two different soils. Growth among families varied significantly, and the interaction between family and soil type was significant. From 2–5 months, leaf number correlated with that of the first month and salin-ity tolerance. …


Multicentury Fire And Forest Histories At 19 Sites In Utah And Eastern Nevada, Emily K. Heyerdahl, Peter M. Brown, Stanley G. Kitchen, Marc H. Weber Jan 2011

Multicentury Fire And Forest Histories At 19 Sites In Utah And Eastern Nevada, Emily K. Heyerdahl, Peter M. Brown, Stanley G. Kitchen, Marc H. Weber

Aspen Bibliography

Our objective is to provide site-specific fire and forest histories from Utah and eastern Nevada that can be used for land management or additional research. We systematically sampled fire scars and tree-recruitment dates across broad gradients in elevation and forest type at 13 sites in Utah and 1 in eastern Nevada to characterize spatial and temporal variation in historical fire regimes as well as forest structure and composition. We collected similar data non-systematically at five additional sites in Utah. These 19 sites include a broad range of forest types (from pinyon-juniper woodlands to spruce-fir forests) and fire regime types. In …
