摘要
甘薯(Ipomoea batatas L.)是一种适应性强、高产、多用途的粮食作物。丛枝菌根真菌(AMF)是一种广泛分布的能与宿主建立互惠共生关系的真菌。AMF能够定殖于甘薯根系,其菌丝的延伸不仅扩大了根系吸收养分的范围,还促进了根系分泌有机碳等物质,起到改善宿主根际环境、活化土壤养分的作用。接种AMF能促进甘薯对养分的吸收利用,调控块根的形成和膨大。本文围绕甘薯与AMF的共生效应,综述AMF与甘薯共生关系的建立、AMF与甘薯共生效应的影响因素、AMF促进甘薯生长发育的作用机制。最后,分析了目前甘薯与AMF共生效应研究中的局限,并针对存在问题进行探讨和展望,为甘薯等作物可持续高效生产提供理论基础和应用依据。
Sweet potato(Ipomoea batatas L.)is an adaptable,high-yield and multi-purpose food crop.Arbuscular mycorrhiza fungi(AMF)are widely distributed fungi that can establish a symbiotic relationship with their hosts.AMF can colonize sweet potato roots.The extension of AMF mycelium not only expands the range of nutrient absorption by roots,but also promotes the secretion of organic carbon and other substances by roots,which plays a role in improving the host rhizosphere environment and activating soil nutrients.AMF inoculation can promote the absorption and utilization of nutrients in sweet potato,and regulate the formation and expansion of root tubers.In this paper,the establishment of symbiotic relationship between AMF and sweet potato,the influencing factors of symbiotic effect between AMF and sweet potato,and the mechanism of AMF promoting the growth and development of sweet potato were reviewed.Finally,the limitations of the current research on the symbiotic effect of sweet potato and AMF were analyzed,and the existing problems were discussed and prospected.This study provides theoretical basis and application basis for the sustainable and efficient production of sweet potato and other crops.
