Investigation of dynamics of carbon, nitrogen and the starch pool from winter oilseed rape hybrids under drought stress for indication of genotypes with high stress compensation. Part 1: Investigation of carbon and nitrogen dynamics in the growth chamber and greenhouse
Project
Project code: ZALF-759
Contract period: 01.05.2012
- 30.04.2015
Purpose of research: Applied research
Many rape plant varieties try to avoid stress by extending their ontogeny. Such plants are less suitable in the practice. Therefore, in future, the breeding of stress-compensating genotypes and export from the leaf and ?will have to focus on plants that are capable of accelerated carbon remobilization and export from the leaf and in which the nitrogen shift increasingly takes place toward seeds. The project is a joint project of ZALF and NPZ. The project shall analyze yield-forming processes in their dynamics following drought stress. These include the 14C and 15N distribution patterns in the vertical profile based on the individual compartments of leaf, root and shoot in relation to the fluctuating starch pool. With means of growth curves based on time rows of biomass of individual plant organs, leaf area indices and soil parameters such as water and Nmin contents, the tracer distributions can be represented as absolute mass flows.
