可溶性硅在植物抵御病害中的作用

 硅是地球表面最丰富的元素之一。尽管硅在植物中的生理和营养作用显得很有限,但其在抵御病害方面的特殊"本领"已引起研究者的广泛重视。本文从硅在植物抵御病害中的作用、施用方式及其抗病机理等几个方面,对国外有关娃在植物抗病中作用的研究进展作了较为全面的综述,并提出了这一研究领域存在的若干问题。

THE ROLE OF SOLUBLE SILICON IN DISEASE MANAGEMENT OF PLANT

Silicon (Si) is one of the most abundant elements on the surface of the earth. Although its physiological and nutrient roles in plant are apparently minimal and poorly understood, its special ability in disease management has been paid attention by researchers and consumers. Progresses in the study of soluble silicon are reviewed as following aspects:its role in disease management of plant, its mode of action and its disease-resistant mechanism. Several problems in this research field are also metioned at the end of this paper.
