摘要:

钾是马铃薯生长发育必需的矿质营养元素之一,对马铃薯生长发育和块茎形成至关重要,钾素吸收和利用效率低是中国马铃薯生产中重要的限制因素之一。本研究从钾素营养效率含义与评价、作物钾高效基因型的鉴定与评价、钾高效吸收的生理基础和钾高效利用的生理基础4个方面,总结归纳了国内外各类作物钾高效品种鉴选的方法和指标。提出选育钾高效基因型品种是提高马铃薯钾素利用效率的有效途径之一,更具有科学意义和现实意义。同时对未来马铃薯钾高效基因型鉴选研究方向进行了展望,以期为马铃薯高产和钾素高效利用提供参考。

Abstract:

Potassium is one of the essential mineral nutrients for potato growth and development, and is crucial for potato growth and tuber formation. The low efficiency of potassium absorption and utilization is one of the important limiting factors in potato production in China, and screening the potato genotypes with high potassium efficiency is the best way to enhance the potassium utilization and deal with low potassium stress in potato. In this paper, the methods and indexes for screening of high potassium efficiency varieties of various crops in China and abroad were summarized from four aspects: the definition and assessment of potassium efficiency, the identification and evaluation of crop genotypes with high potassium efficiency, the physiological basis of high potassium absorption and the physiological basis of high potassium utilization. Combining with the characteristics of potato potassium requirement, the feasible methods and influencing factors for screening potato genotypes with high potassium efficiency were put forward, and the future research direction for improving potato potassium efficiency was prospected so as to provide a reference for the high yield and high potassium utilization of potato.
