Low field NMR has been used in several studies for investigation of leaf water status [1-2]. An original interpretation of the multi-exponential transverse relaxation signal of leaf tissue taking into account subcellular compartmentation and heterogeneities at the tissue level has been recently proposed for the oilseed rape leaves [3-4]. Applied on a wide leaf panel collected from plant grown in controlled conditions, the NMR relaxometry was shown to be able to detect slight variations in senescence associated structural modifications of leaf tissues. The aims of the present study was to demonstrate the potentiality of NMR to provide robust indicators of the leaf development stage for plant grown directly in field and to illustrate its potential for in situ measurements with a mobile-NMR lab.
