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.
