abstract = {Chlorophyll fluorescence (ChlF) is a powerful non-invasive
technique for probing photosynthesis. Although proposed as a
method for drought tolerance screening, ChlF has not yet
been fully adopted in physiological breeding, mainly due to
limitations in high-throughput field phenotyping
capabilities. The light-induced fluorescence transient
(LIFT) sensor has recently been shown to reliably provide
active ChlF data for rapid and remote characterisation of
plant photosynthetic performance. We used the LIFT sensor to
quantify photosynthesis traits across time in a large panel
of durum wheat genotypes subjected to a progressive drought
in replicated field trials over two growing seasons. The
photosynthetic performance was measured at the canopy level
by means of the operating efficiency of Photosystem II
(urn:x-wiley:01407791:media:pce14136:pce14136-math-0072) and
the kinetics of electron transport measured by reoxidation
rates
(urn:x-wiley:01407791:media:pce14136:pce14136-math-0073 and
urn:x-wiley:01407791:media:pce14136:pce14136-math-0074).
Short- and long-term changes in ChlF traits were found in
response to soil water availability and due to interactions
with weather fluctuations. In mild drought,
urn:x-wiley:01407791:media:pce14136:pce14136-math-0075 and
urn:x-wiley:01407791:media:pce14136:pce14136-math-0076 were
little affected, while
urn:x-wiley:01407791:media:pce14136:pce14136-math-0077 was
consistently accelerated in water-limited compared to
well-watered plants, increasingly so with rising vapour
pressure deficit. This high-throughput approach allowed
assessment of the native genetic diversity in ChlF traits
while considering the diurnal dynamics of photosynthesis.},
