Phylogenetic relationships among seed plant taxa, especially within the gymnosperms, remain contested. In contrast to angiosperms, for which several genomic, transcriptomic and phylogenetic resources are available, there are few, if any, molecular markers that allow broad comparisons among gymnosperm species. With few gymnosperm genomes available, recently obtained transcriptomes in gymnosperms...
Karlgren, A. 2013. Genetic Control of Annual Growth Rhythm in the Conifer Norway Spruce (Picea Abies L. Karst). Acta Universitatis Upsaliensis. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1014. 49 pp. Uppsala. ISBN 978-91-554-8581-8. Norway spruce (Picea abies L. Karst) is a conifer belonging to the group gymnosperms and is an ecologically...
The application of Artificial Intelligence (AI) techniques to the problem of botanical identification is not particularly widespread even less so on Internet. There are several interactive identification systems but they usually deal with raw knowledge so it appears that “research and development of web-based expert systems are still in their early stage” (Li et al., 2002). In this paper we pre...
The implementation of intelligent systems is not particularly widespread in the field of Botany and even less so on Internet. At present, we can currently only find hypertext documents or databases which store unprocessed information. The GREEN (Gymnosperms Remote Expert Executed Over Networks) System is presented as the application of Artificial Intelligence techniques to the problem of botani...
Sapwood characteristics, such as sapwood area well thermal and hydraulic conductivity, are linked to species-specific function resource allocation water transport tissues (xylem). These characteristics often unknown thus a major source of uncertainty in sap flow data processing transpiration estimates because bulk rather than values usually applied. Here, we analyzed the fifteen common tree spe...
