根系管理是苹果栽培生产的关键。在土壤载体生产中，吸收根的大量发生和控制生长根的旺长，能够有效的提高叶片光合效率，提高花芽分化及枝条贮藏营养，稳定树势；而生长根则有利于提高树势。因此，大田条件下，利用高通量测序技术，深入了解生长根与吸收根基因表达差异，构建根系功能基因组数据库，并利用分子生物学技术对重要差异基因进行功能解析，对于根系基因组学的发展具有重要的理论基础作用，同时对苹果砧木根系构型的诱导、土壤管理及栽培制度改革具有重要理论指导作用。

Root is the basis of the fruit trees, root structure and function regulation is the key of orchard soil management. Apple roots have different functions, and in the soil, absorbing roots can improve the photosynthetic efficiency, prevent the senescence of leaf, increase branches’ storage nutrition, regulate the growth of autumn shoot, improve the quality of flower bud, and increase fruit yield. As well, the growing roots can improve the vigor of the tree. Therefore, under field conditions, by RNA sequencing techniques, we can look into the difference gene expression between growing root and absorbing root, by building root genomes database, as well as by using of molecular biology technology to analysis of gene function, all of these are significant theoretical importance for the development of the root genomics and of practical significance to transform root architecture of apple stock, soil management as well as reforming management regimes.
