摘要
磷是大麦生长发育必需的大量元素之一,其影响大麦的产量和品质。土壤中有效磷含量低,生产上通过施用过量的不可再生磷肥来缓解低磷胁迫。只有全面掌握大麦对低磷胁迫的响应机制,培育磷高效品种,才能从根本上解决生产上对磷肥的过度依赖。本文系统总结了近些年大麦在根系形态、生理和分子水平上对低磷胁迫的响应,以及大麦耐低磷位点和磷相关基因挖掘的研究进展,对磷高效利用优质大麦育种提供参考。
Phosphorus is one of the macronutrients for barley growth and development,and affects barley yield and quality.The available inorganic phosphate content in soil is low,and excessive non-renewable phosphate fertilizer is applied in production to alleviate low phosphate stress of barley.The over use of phosphate fertilizer in production can only be effectively addressed by fully comprehending the mechanism underlying barleyʼs sensitivity to low phosphate stress and developing varieties with high phosphate consumption efficiency.This paper systematically summarizes the research progress of barley response to low phosphate stress in root morphology,physiological aspects and molecular level,as well as the progress of identification of low phosphate tolerance loci and genes,which will facilitate to breed high-quality barley with high phosphate utilization efficiency.
