A Nitrogen-led Model of Grass Growth
This model is built by considering the utilization rate of nitrogen as the first step in calculating the rate of growth of the various organs of a grass crop. The amount of carbohydrate determines whether there are sufficient carbon skeletons and sufficient energy available to support synthesis of new material. Growth of roots, tillers}stems and leaves is simulated with leaf divided into photos...
متن کاملAssociative Nitrogen Fixation by Klebsiella spp.: Adhesion Sites and Inoculation Effects on Grass Roots.
Adhesion sites on grass roots for Klebsiella strains carrying type 3 or type 1 fimbriae or both were determined. Adhesion of the strains to the roots of Poa pratensis and Festuca rubra was highly localized; the bacteria adhered strongly to root hairs and with a markedly lower efficiency to the surface of the zone of elongation and to the root cap mucilage. No adhesion to the epidermal cells bet...
متن کاملGrass-roots Class Alignment
Current ontology alignment practices adopt a centralized approach: the alignment task is carried out by a domain expert, possibly with the help of some ontology alignment tools. In a Peer-to-Peer environment, each end-user (peer) may explicitly or implicitly generate ontology alignments for their own purposes during its own use of the semantic data. This kind of end-user-generated ontology alig...
متن کاملGrass-roots Semantic Web Tools
One of the biggest challenges of the Semantic Web is to make its tools usable by ordinary users for grass-roots production and integration of semantic information. This paper introduces the ongoing research on this issue in our research group at the Information Sciences Institute. 1. RESEARCH OVERVIEW Despite years of intense work and research on the Semantic Web, it has not become a reality. O...
متن کاملNitrogen stress affects the turnover and size of nitrogen pools supplying leaf growth in a grass.
The effect of nitrogen (N) stress on the pool system supplying currently assimilated and (re)mobilized N for leaf growth of a grass was explored by dynamic ¹⁵N labeling, assessment of total and labeled N import into leaf growth zones, and compartmental analysis of the label import data. Perennial ryegrass (Lolium perenne) plants, grown with low or high levels of N fertilization, were labeled wi...
