“…They concluded that non-invasive optical methods all provided reliable estimates of leaf Chl. However, some reflectance indices (Gitelson and Merzlyak, 1994) consistently out-performed two commercially available hand-held Chl absorbance meters CCM-200 and the SPAD-502. Steele et al (2008) further showed that the SPAD-502 has adequate sensitivity to Chl content below 300 mg m-2.…”

SummaryThe objective of this study was to develop a rapid non-destructive technique to estimate total chlorophyll (Chl) content in a maize canopy using Chl content in a single leaf. The approach was (1) to calibrate and validate a reflectance-based nondestructive technique to estimate leaf Chl in maize; (2) to quantify the relative contribution of each leaf Chl to the total Chl in the canopy; and (3) to establish a relationship between leaf Chl content and total Chl in a maize canopy. The Red Edge Chlorophyll Index Clred edge = (RNIRIRred edge)-l based on reflectances, R, in the red edge (720-730nm) and near infrared (770-800nm) was found to be an accurate measure of maize leaf Chl. It was able to predict leaf Chl ranging from 10 to 805 mg Chl m-2 with root mean-square error less than 38 mg Chl mP2. Relationships between Chl content in each maize leaf and total canopy Chl content were established and showed that Chl in the collar leaf before silking or ear leaves explained more than 80% and 87% of the variation in total Chl in a maize canopy, respectively. Thus, non-destructive measurements of both reflectance and area of a single leaf (either collar or ear) can be used to accurately estimate total Chl content in a maize canopy.

“…The reference waveband largely normalizes for reflectance variations due to chloroplast movement and content of other pigments. The NDVI was calculated as (R 750 -R 705 )/(R 750 + R 705 ), where R 750 and R 705 are reflectance of the near-infrared region and the edge of red (chlorophyll) absorption wavebands, respectively (Gitelson & Merzylak 1994;Gamon & Surfus 1999).…”

“…In addition, we examined the use of two leaf reflectance indices -the photochemical reflectance index (PRI; a measure of xanthophyll cycle pigment activity; Peñuelas, Filella & Gamon 1995;Gamon et al 1997;Peñuelas et al 1997;Gamon & Surfus 1999) and a modified normalized difference vegetation index (NDVI; a measure of chlorophyll content; Gitelson & Merzylak 1994;Gamon & Surfus 1999) -to detect variations in pigment content and carbon assimilation. These reflectance indices are of particular interest because they can be measured quickly, non-destructively, and in situ and may be useful for scaling the physiological response to [CO 2 ] enrichment from leaf to canopy to stand levels (cf.…”

Lifelong exposure to elevated concentrations of atmospheric CO2 may enhance carbon assimilation of trees with unlimited rooting volume and consequently may reduce requirements for photoprotective pigments. In early summer the effects of elevated [CO2] on carboxylation and light utilization of mature Quercus pubescens trees growing under chronic [CO2] enrichment at two CO2 springs and control sites in Italy were examined. Net photosynthesis was enhanced by 36 to 77%. There was no evidence of photosynthetic downregulation early in the growing season when sink demand presumably was greatest. Specifically, maximum assimilation at saturating [CO2], electron transport capacity, and Rubisco content, activity and carboxylation capacity were not significantly different in trees growing at the CO2 springs and their respective control sites. Foliar biochemical content, leaf reflectance index of chlorophyll pigments (NDVI), and photochemical efficiency of PSII (ΔF/Fm′) also were not significantly affected by [CO2] enrichment except that starch content and ΔF/Fm′ tended to be higher at one spring (42 and 15%, respectively). Contrary to expectation, prolonged elevation of [CO2] did not reduce xanthophyll cycle pigment pools or alter mid‐day values of leaf reflectance index of xanthophyll cycle pigments (PRI), despite the enhancement of carbon assimilation. However, both these pigments and PRI were well correlated with electron transport capacity.

Abstract:The development of spectral methods of remote sensing, including measurement of a photochemical reflectance index (PRI), is a prospective trend in precision agriculture. There are many works which have investigated the connection between photosynthetic parameters and PRI; however, their results varied and were sometimes contradictory. For this paper, we performed a meta-analysis of works in this field. Here, only linear correlations of PRI with photosynthetic parameters-including quantum yield of photosystem II (∆F/Fm'), nonphotochemical quenching of chlorophyll fluorescence (NPQ), and light use efficiency (LUE)-were investigated. First, it was shown that the correlations were dependent on conditions of PRI measurements (leaf or canopy; artificial light or sunlight). Second, it was shown that a minimal level of the photosynthetic stress, and the variation of this level among investigated plants, can influence the linear correlation of PRI with ∆F/Fm' and NPQ; the effect was dependent on conditions of measurements. In contrast, the distribution of LUE among plants did not influence its correlation with PRI. Thus, the meta-analysis shows that the distribution of photosynthetic parameters among investigated plants can be an important factor that influences the efficiency of remote sensing on the basis of the PRI measurement.
