. In our study, when the 750 WS
plants were grown under good water availability (first DAWW)
the higher ITE value was due solely to the lower E, while under
moderate (three DAWW) and severe water deficit (five DAWW) a
higher Pn could explain the higher ITE. Instantaneous transpiration
efficiency derived from a greater Pn is a positive aspect for
plants growing under water deficit because it can contribute more
meaningfully to increase the dry matter accumulation
