柑橘硼营养研究现状与展望
Advances on boron nutrition of citrus

硼是植物必需的微量元素之一。缺硼现象在一些柑橘主产国（如巴西、中国）十分普遍。本文综述了国内外有关柑橘硼素研究的最新进展，包括柑橘体内硼的含量及分布、硼移动性、硼胁迫响应、硼效率差异的耐受机制、硼营养诊断与矫正，重点讨论了砧木和接穗品种间的硼效率差异以及柑橘叶片诊断的标准等，并据此指出今后可能在砧穗之间硼胁迫响应的分子机制、菌根与硼吸收利用的关系等方面取得较大进展。
Boron is an essential microelement for higher plants.Boron deficiency is widespread in several major citrus-growing countries,including Brazil and China.The advances on boron nutrition of citrus including boron concentration and distribution，boron mobility，physiological and molecular responses to boron stresses，mechanisms of differences in boron efficiency，and diagnosis of boron deficiency were reviewed.Boron efficiency of citrus scion-rootstook combinations and the criterion of leaf diagnosis in citrus was emphasized.Studies of boron nutrition in citrus concerning with the molecular mechanisms of the interaction between scion and rootstock，and the relationship between mycorrhizas and utilization of boron were prospected.
