Sammanfattning : Biologically harmful ultraviolet-B radiation (UV-B, 280-320 nm) is increasing at the Earth´s surface owing to stratospheric ozone depletion. This is of global concern due to potential impacts of enhanced UV-B radiation on the biosphere. LÄS MER
- Detta är en avhandling från Lund University, Faculty of Science, Department of Astronomy and Theoretical Physics
Sammanfattning : Recent evidence has revealed the role of mechanical cues in the development of shapes in organisms. This thesis is an effort to test some of the fundamental hypotheses about the relation between mechanics and patterning in plants. To do this, we develop mechanical models designed to include specific features of plant cell walls. LÄS MER
3. From growth cessation to bud burst conifer seedling development in response to nursery culture and environmental stimuliDetta är en avhandling från Uppsala : School for Forest Management, Swedish University of Agricultural Sciences
Sammanfattning : In Sweden, 350-400 million seedlings are produced annually for forest regeneration. About one third of these are overwintered in frozen storage, necessitating accurate methods to assess storability. Young transplants of Norway spruce (Picea abies (L.) Karst. LÄS MER

Sammanfattning : The stratospheric ozone depletion and the concomitant increase in ultraviolet-B (UV-B, 280-320 nm) radiation is of global concern due to the effects of UV-B on living organisms. To investigate the effects of increased levels of UV-B, a field irradiation system was established at a subarctic dwarf shrub heath in Northern Sweden (68 °N). LÄS MER
5. Modelling the development of phyllotactic patterns at the shoot apical meristem of Arabidopsis thalianaDetta är en avhandling från Biology building
Sammanfattning : The study of phyllotactic patterns have a long history, but the bulk of our detailed understanding of developmental processes in plants comes from research conducted in the last thirty or forty years. New modern techniques have made it possible to study plants in ways that previously was not possible. LÄS MER
