“…In At + 10 • C, 'Star' showed a better photosynthetic performance than 'Jewel' and 'Bluecrisp' because of an increase in Y(II). Roostaei et al (2011) obtained similar correlation coefficients to the present ones (Table 4). However, their "r" values between the fluorescence parameters were higher than those found in this work, probably due to the fact that their data was separated in relation to water condition, whereas the correlation matrix presented in our study were grouped all environmental conditions.…”

“…Several authors, watering in conditions of heat or water stress and with different species of fruit, vegetables and crops, observed a decrease in Fv/Fm according to the degree of stress applied. (Else et al, 2009;Leakey et al, 2003;Li et al, 2008;Molina-Bravo et al, 2011;Osório et al, 2006;Roostaei et al, 2011;Wright et al, 2009). Chen et al (2012) by subjecting plants to 45 • C observed decreased Fv/Fm, reaching values below 0.6 in different cvs.…”

“…Flexas et al (1999), Osório et al (2006) and Sofo (2011) have reported lower ETR in different fruit species in water stress treatments compared to normal watering, being a good indicator of the photosynthetic apparatus under these conditions. It has also shown to be a good indicator for distinguishing differences between species or genotypes of the same species (Quigg, 2012;Roostaei et al, 2011;Tyystjärvi et al, 2011). However, in C 3 plants under stress conditions, the rate of transport of electrons can remain similar to those seen in control treatments due to the demand from other sources for electrons such as photorespiration and Mehler reaction (Baker and Rosenqvist, 2004;Frachebound and Leipner, 2003;Massacci et al, 2008;Melis, 1999;Silva et al, 2010).…”

“…The sensitivity of the fast fluorescence parameters to drought or osmotic stress has also been identified in barley [18], sorghum [25], rice [26], and maize [27]. There are several studies which have confirmed these findings, including a few studies using field conditions [28,29], but there is still insufficient information on the responses of PSII photochemistry on moderate, slowly progressing drought stress in field conditions and the specific effects of irrigation.…”

Chlorophyll Fluorescence Kinetics May Be Useful to Identify Early Drought and Irrigation Effects on Photosynthetic Apparatus in Field-Grown Wheat

To assess the reliability and sensitivity of non-invasive optical methods to detect the early effects of water deficit in the field, we analyzed the time-series of non-invasive measurements obtained in a dry season in a representative collection of wheat genotypes grown in small-plot field trials, in non-irrigated and irrigated variants. Despite a progressive water deficit and significant yield loss, the measurements indicated very minor changes in chlorophyll content or canopy cover. This corresponded well to the insignificant differences in spectral reflectance normalized difference vegetation index (NDVI) values. On the other hand, we identified the significant and rapid response of fast fluorescence kinetics data following the onset of irrigation. Analysis of parameters showed the main effects of drought were associated with changes in the amplitude of the I–P phase of the OJIP transient, indicating changes at the level of photosystem I and beyond. Statistical analyses identified the integrative parameter performance index PItot as the most sensitive parameter, which well-reflects the differences in responses of the genotypes to water deficit. Our results suggest that focusing on photosynthetic functions detected by the rapid chlorophyll fluorescence records can provide more accurate information on the drought stress level, compared to the structural data obtained by absorbance or reflectance measurements.

“…The perturbation of photosynthesis can be associated with changes to the biochemical reaction of photosystem II, which can be assessed by chlorophyll fluorescence. Alterations in chlorophyll fluorescence parameters have been used to evaluate plant drought tolerance (Maury et al, 1996; Li et al, 2006; O'Neill et al, 2006; Luo et al, 2011; Roostaei et al, 2011). Several QTLs for chlorophyll fluorescence have been identified in different plant species under drought stress (Yang et al, 2007; Kiani et al, 2008; De Miguel et al, 2014; Sukumaran et al, 2016).…”

The temperate wild grass Brachypodium distachyon (Brachypodium) serves as model system for studying turf and forage grasses. Brachypodium collections show diverse responses to drought stress, but little is known about the genetic mechanisms of drought tolerance of this species. The objective of this study was to identify quantitative trait loci (QTLs) associated with drought tolerance traits in Brachypodium. We assessed leaf fresh weight (LFW), leaf dry weight (LDW), leaf water content (LWC), leaf wilting (WT), and chlorophyll fluorescence (Fv/Fm) under well-watered and drought conditions on a recombinant inbred line (RIL) population from two parents (Bd3-1 and Bd1-1) known to differ in their drought adaptation. A linkage map of the RIL population was constructed using 467 single nucleotide polymorphism (SNP) markers obtained from genotyping-by-sequencing. The Bd3-1/Bd1-1 map spanned 1,618 cM and had an average distance of 3.5 cM between adjacent single nucleotide polymorphisms (SNPs). Twenty-six QTLs were identified in chromosome 1, 2, and 3 in two experiments, with 14 of the QTLs under well-watered conditions and 12 QTLs under drought stress. In Experiment 1, a QTL located on chromosome 2 with a peak at 182 cM appeared to simultaneously control WT, LWC, and Fv/Fm under drought stress, accounting for 11–18.7% of the phenotypic variation. Allelic diversity of candidate genes DREB2B, MYB, and SPK, which reside in one multi-QTL region, may play a role in the natural variation in whole plant drought tolerance in Brachypodium. Co-localization of QTLs for multiple drought-related traits suggest that the gene(s) involved are important regulators of drought tolerance in Brachypodium.
