硼在植物体内的生理效应及其对几种重要代谢产物影响的研究进展

硼是植物必需的重要微量元素之一，在植物体内起着重要的作用，但是硼在植物中属于难移动的元素，加上我国缺硼土壤分布广泛，因此植物中的缺硼现象比较严重。为了更好的了解硼在植物体内详细的代谢规律，本文综述了微量元素硼在植物体内的生理效应及其调控机制，总结了植物的主要缺硼症状及不同硼水平条件下对植物的生理伤害，并着重分析了硼对几种重要代谢产物包括糖类、蛋白质、核酸、激素等的影响，介绍了微量元素硼影响植物的多种生理代谢过程，指出了硼在影响细胞膜稳定性、蛋白质数量、酚类、酶类等的代谢与分布的关系上仍需进一步深入探讨。

The Progress of Physiological Effect of Boron in Plants and its Impact on Several Important Metabolites

Boron (B) is a special microelement element, it is a micronutrient essential for the normal growth and development of plants, and related to many metabolic activities in plants and plays an important role in the stability of cellular structure. Boron deficiency is a worldwide agricultural problem, causing the decreases in yield and quality of crops. Great progresses have been made in B study in plants since recent years. This article reviews the application effects of the microelement B in plants and its physiological regulation mechanisms, and introduces the physiological damage to plants under different B level conditions, and indicates that the microelement B affects the physiological metabolism of plants, as well as B impacts on several important metabolites such as carbohydrates, proteins, nucleic acids, hormones. But the physiological function of B is indirect in these metabolic activities and its mechanism should be further examined. Some suggestions for further studies of physiological function of B are also proposed.
