项目摘要

This proposal for LINK funded project will build on a solid base of work currently underway, funded through existing LINK programmes, BBSRC, directly by industry, the Scottish Government and the NIAB Trust fund. The proposed study will seek to initiate a better understanding of wheat root growth, morphology and functional relationships with nutrient and water uptake. Methods to describe roots in a diverse range of winter wheat types will be implemented in controlled glasshouse conditions and in the field. The project will form the foundation for improving nutrient sequestration and conversion in this important UK crop through initiation of pre-breeding and development of ideal root ideotypes suitable for use in current and future wheat production. The consortium will concentrate on efficient or enhanced use of resources, especially nitrogen and phosphate and will consider interactions with water availability. In addition, the importance of interactions with beneficial mycorrhizal fungi on nutrient sequestration and the negative impact of soil-borne pathogenic fungi on susceptible genotypes will be considered under field conditions. Finally, the potential impact of agrochemical seed coats on root performance will be assessed. Overall, research in root biology leading to increases in nutrient uptake efficiency will contribute to reductions in diffuse pollution and will substantially reduce green house gas emission due a reduction in the use of nitrogen fertilisers in wheat cultivation

LINK资助项目的建议将建立在目前正在进行的工作的坚实基础上，通过现有的LINK计划，BBSRC，直接由行业，苏格兰政府和NIAB信托基金资助。拟议的研究将寻求更好地了解小麦根系生长，形态和功能与养分和水分吸收的关系。描述不同类型冬小麦根系的方法将在受控温室条件下和田间实施。该项目将通过启动预育种和开发适用于当前和未来小麦生产的理想根系理想型，为改善这一重要英国作物的养分封存和转化奠定基础。该联合体将集中精力有效或加强资源的利用，特别是氮和磷酸盐，并将考虑与水供应的相互作用。此外，在田间条件下，将考虑与有益的菌根真菌的相互作用对养分螯合的重要性和土传病原真菌对易感基因型的负面影响。最后，将评估农用化学品种皮对根系性能的潜在影响。总体而言，根系生物学的研究导致养分吸收效率的提高，将有助于减少扩散污染，并将大大减少绿色温室气体排放，因为在小麦种植中减少氮肥的使用
