• [Objective][Objective]The aim of this study was to monitor the leaf relative water content( RWC) and water potential( Ψw) in structured Eucalyptus camaldulensis and E. tereticornis populations by Near Infrared spectroscopy( NIRS). [Method ]The samples were collected from the breeding population,which contained 21 families of 7provenances for E. camaldulensis,and 26 families of 5 provenances for E. tereticornis. A total of 20 average-growth seedlings per family were chosen,divided into 5 groups randomly,and were watered every day by replenishing 100%,70%,50%,30% and 0% of the average water loss of these seedlings from pots by evapotranspiration,respectively. In60 days after water controls,three seedlings per water control and per family were chosen,of which the top second pair fully expanded leaves were used to be scanned with a portable near infrared spectrometer for getting the NIRS spectra.After the scanning,the leaf RWC and leaf Ψwwere measured. The measurements were conducted once a day for consecutive 18
