钙在植物营养中的作用

钙是植物维持正常生命活动所必需的营养元素之一,在植物体内执行多种生理功能;目前,钙已不再仅仅被看作是一种参与构成植物各种器官、组织的营养物质,而且还作为信号物质调节细胞功能,为植物体内各种代谢活动的正常进行提供保障;此外,钙对植物赖以生长的土壤介质的改良也发挥重要作用。因此,钙在植物营养生理中的作用受到人们的广泛关注。本文在查阅大量文献的基础上,对当前这方面的研究成果及动态进行综述。

The Function of Calcium in Plant Nutrition

Calcium is one of the necessary nutritive elements to maintain plant's normal life activities,and it performs a variety of physiological functions in fronds;Currently,calcium is no longer viewed only as a kind of nutritive material which participates in making diversified organs and tissues of plants,but also regulates cell's functions as signal material,so it ensures that all kinds of metabolic activities in plants are on the rails;In addi- tion,calcium also plays an important role in improving the soil medium in which plants grow.Therefore,the function of calcium in plant nutrition physiology has been concerned widely.This article summarizes the current research results and trends in this field on the basis of plentiful literatures.
