铝毒害是酸性土壤中作物生长的主要限制因素。柑橘是生长在酸性或强酸性土壤中的亚热带果树,容易受到铝毒害的危害,使其果实品质和产量下降。近十年来,国内外在柑橘铝毒害方面已有较深入的研究。首次概述柑橘铝毒害症状、铝毒害对柑橘矿质元素吸收、光合作用的影响、柑橘品种间耐铝差异、柑橘耐铝机制、耐铝响应基因鉴定等方面的最新研究进展,并展望未来的研究方向。
Aluminum toxicity is a major limiting factor in crop growth in acid soil.Citrus as a predominant subtropical fruit tree grown in acid or strongly acid soil,is vulnerable to aluminum toxicity,which results in decrease of fruit quality and yield.Over the past decade,reseach on Al toxicity and aluminum tolerance mechanism in citrus has achieved great progresses. This paper reviews the symptoms of citrus aluminum toxicity,its effect on absorption of mineral elements and photosynthesis,difference in resistance to aluminum of citrus varieties,mechanism of aluminum tolerance in citrus,indentification of aluminum response gene,etc.And the prospect of further research is also briefly discussed.
