In the almost century since the establishment of boron (B) as an essential plant nutrient, its roles in plant growth and development have been identified, and the mechanism for B transportation explained. This review relates the yield response of crops, measured as B efficiency i.e. productivity when B is limiting relative to when it is not, to the B supply logistics and requirement of different tissues and organs. Yield is depressed by B deficiency in graminaceous cereals primarily by impaired development and function of the stamen and pistil, but in dicots the adverse effects are expressed as structural damage to various organs. Boron-efficient cereal genotypes are readily identifiable by their successful grain set under limited B, while the quantitative trait loci associated with B efficiency provide a useful selection tool for dicots. The relevance to breeding for B efficiency of the numerous BOR1 and NIP genes controlling active B transport identified in many crops will depend on how close their up-regulation in a deficiency is associated with B efficiency. Understanding of the yield impact of B deficiency is useful in dealing with crop choice and the management of germplasm and B fertilizer.

生产力限制硼缺乏的影响,综述
自从硼 (B) 成为植物必需营养素以来的近一个世纪里,它在植物生长和发育中的作用已被确定,并解释了 B 运输的机制。这篇综述将作物的产量响应与 B 供应物流和不同组织和器官的需求联系起来,以 B 效率衡量,即当 B 有限时的生产力,相对于没有时。禾本科谷物中的 B 缺乏主要是由于雄蕊和雌蕊的发育和功能受损而降低了产量,但在双子叶植物中,不利影响表现为对各种器官的结构损伤。硼高效谷物基因型很容易通过它们在有限 B 下的成功谷物集来识别,而与 B 效率相关的数量性状基因座为双子叶植物提供了有用的选择工具。在许多作物中发现的控制活性 B 转运的众多 BOR1 和 NIP 基因与 B 效率育种的相关性将取决于它们在缺乏时的上调与 B 效率相关的程度。了解 B 缺乏症对产量的影响有助于处理作物选择以及种质和 B 肥料的管理。
