Development status and research trend of zinc-rich wheat breeding
The current distribution of zinc content in farmland soil,the impact of zinc on the nutritional quality of wheat grains,the absorption and accumulation characteristics of zinc by wheat,and the ways to enhance zinc nutrition in wheat grains were summarized and analyzed.The distribution pattern of zinc content in soil was closely related to topog-raphy,geological structure,and ecological environment.In some wheat producing areas,the zinc content in soil is rela-tively low.Zinc is an important trace element that affects the starch and protein content of wheat grains.It was generally absorbed by plant roots and transported to the aboveground part under pressure or transpiration,or horizontally trans-ported to the phloem,where it was transported upwards or downwards and then transported to various tissues and organs.The ways to enhance zinc in wheat include genetic improvement breeding,agronomic improvement,and application bio-technology.The research results provide some new ideas for zinc-rich wheat breeding.
