Abstract: | Influence of the nitrogen-nutrition on qualitative and quantitative characteristics of seeds of rape (Brassica napus L.) An experiment was carried out under greenhouse conditions to analyse the influence of nitrogen nutrition on qualitative and quantitative characteristics of seeds of rape, variety “Erglu”. Increasing the level of nitrogen fertilization raised the crude protein content during the whole period of seed growth but decreased the lipid content during the main seed growth stages. Nitrogen nutrition only changed the fatty acid composition significantly during the early stages of seed growth. Increasing nitrogen fertilization resulted at maturity in a trend towards higher contents of palmitic and linoleic acids but in a lower content of oleic acid. At maturity the lipid content was not influenced by the level of nitrogen nutrition. The differences in seed-yield per pod between the main branch and axillary branch 5 became smaller when nitrogen nutrition was increased. |
