Abstract

植物体内的水分状态与传输过程是土壤-植物-大气连续体( SPAC) 水分传输理论的
核心内容,也是研究植物水分利用与调控的基础.植物体内水分的传输过程受外界环境影响
较大,植物需要通过对体内水分状态的适当调整来适应环境变化和维持自身的生长发育.由
于蒸发通量、压力室、高压流速仪、热脉冲等传统检测方法往往会对植株造成破坏和损伤,因
此难以准确反映和定量描述植物体内水分传输的真实过程.核磁共振技术( NMR) 由于其无
损、非侵入的特点,在植物水分分布和传输相关研究中日益得到关注.本文概述了NMR 在检
测植物体内水分分布、传输以及含量测定等方面的研究进展,还分析了目前NMR 技术在
SPAC 系统研究中存在的问题及可能的解决方法,并指出NMR 技术将来可能在植物水分生
理、植物与环境互作以及水分代谢等相关研究领域的应用.NMR 技术在SPAC 系统研究中的
应用在我国仍处于初级阶段,开发户外便携式、开放式检测仪器是NMR 技术在SPAC 研究领

Other Abstract

Status and transport of water in plant body are the main contents of study of soil-plantatmosphere
continuum ( SPAC) ,as well as the base for use and regulation of agricultural water.
The process of water transport in plant can be deeply influenced by the environments. Thus,plant
needs to adjust its water status to accommodate the environmental change to sustain its own growth
and development. Traditional methods for plant water monitoring,such as evaporation flux,pressure
chamber,high pressure flow meter,heat pulse,and so on,usually cause damage or even destruction
of plant body and disturb the original water status. Thus,they are not able to truly and precisely
detect and reflect the real water status of plant. Nuclear magnetic resonance ( NMR) is a nondestructive
and non-invasive technique which can be used for the measurement of water molecular
displacement and transportation. This study aimed to provide an overview of the applications of NMR
technique in the study of water distribution and transport in plant roots and stems,as well as the water
content in plant cells and tissues. In addition,the existing main problems and possible solutions
were analyzed for the applications of NMR in SPAC studies. Several important issues were proposed.for the acquisition of more precise and reliable detection signals. It was suggested that the NMR
technique would probably make important progress in the relevant fields such as plant water physiology,
plantenvironment interactions,and water metabolism. In general,the application of NMR in
SPAC system study was still in its infancy in China. The deeper application and expansion of NMR
in SPAC study would depend on the development of portable and open NMR equipment that could
be easily applied for different plants in field.
