果树硼营养元素研究进展

为了解目前硼元素研究现状，为在果树生产上有针对性的使用硼元素提供参考意见及为其今后的研究提供理论基础与依据，归纳了果树对硼元素的吸收、转运与分布特点，详叙了硼元素对细胞壁结构及细胞内酶活性等的生理功能、硼元素与其他微量元素的关系以及硼元素对果实品质的影响。认为硼元素的吸收与转运存在三种形式，且在作物体内硼以酸的形式存在，并通过与顺式二元醇缩合成酯行使生理功能；硼元素对维持植物细胞壁结构，调节细胞壁酶活性具有一定的影响，此外对果实产量、风味品质及贮藏性也具有一定影响；硼元素与磷元素、氮元素存在促进作用，与钙元素存在拮抗关系。指出硼元素今后研究重点，以期为硼元素研究与发展提供借鉴。

Boron Nutrition in Fruit Trees: Research Progress

To understand current research status of boron, and provide references for the targeted use of boron in fruit production, the authors summarize the absorption, transportation and distribution characteristics of boron in fruit trees. The physiological functions of boron on cell wall structure and intracellular enzyme activity, the relationship between boron and other trace elements, and the effects of boron on fruit quality are also described in detail. There are three forms of absorption and transportation of boron which exists in the form of acid in crops and performs physiological functions by condensing with cis-diol to synthesize ester. Boron has effects on the maintenance of plant cell wall structure and regulation of cell wall enzyme activity, as well as on fruit yield, flavor quality and storage. There is a mutual promotion between boron and phosphorus and nitrogen, while, an antagonistic relationship between boron and calcium.
