“…Studies on photosynthetic characteristics of crops such as Zea mays [ 7 – 9 ], Oryza sativa [ 10 – 12 ], and Glycine max [ 13 , 14 ] have been extensively performed. Also, inheritance of photosynthetic characteristics [ 15 – 17 ], diurnal variation of net photosynthetic rate [ 18 , 19 ], and seasonal variation [ 20 , 21 ] have been reported in the separated sugarcane seedling populations. Indices such as shape, size, quantity, and spatial distribution of leaves are directly related to the light environment and light utilization rate of the population.…”

During sugarcane growth, the Early Elongation stage is critical to cane yield formation. In this study, parameters of 17 sugarcane varieties were determined at the Early Elongation stage using CI-301 photosynthesis measuring system and CI-100 digital plant canopy imager. The data analysis showed highly significant differences in leaf area index (LAI), mean foliage inclination angle (MFIA), transmission coefficient for diffused light penetration (TD), transmission coefficient for solar beam radiation penetration (TR), leaf distribution (LD), net photosynthetic rate (PN), transpiration rate (E), and stomatal conductance (GS) among sugarcane varieties. Based on the photosynthetic or canopy parameters, the 17 sugarcane varieties were classified into four categories. Through the factor analysis, nine parameters were represented by three principal factors, of which the cumulative rate of variance contributions reached 85.77%. A regression for sugarcane yield, with relative error of yield fitting less than 0.05, was successfully established: sugarcane yield = −27.19 − 1.69 × PN + 0.17 × E + 90.43 × LAI − 408.81 × LD + 0.0015 × NSH + 101.38 × D (R 2 = 0.928**). This study helps provide a theoretical basis and technical guidance for the screening of new sugarcane varieties with high net photosynthetic rate and ideal canopy structure.

“…Over the last decades, developments in instrumentation and methodology have improved the precision of estimates of chlorophyll (Chl) content and fluorescence. As a result, significant advances have been made in defining selection criteria in a multitude of field crops (Araus et al 1998, Earl and Tollenaar 1999, Lima et al 1999, Zhang et al 2000. Chl fluorescence is a quantitative and qualitative indicator of light-dependent photosynthetic processes, and has been suggested as a screening method to improve heat tolerance of some tropical fruit crops (Yamada et al 1996), drought tolerance in durum wheat (Flagella et al 1995) and heat tolerance in bean (Petkova et al 2007).…”

A field‐experiment (2004/2005 and 2005/2006 seasons) was conducted in the coastal plain of south‐eastern Sicily (37°03′N, 15°18′E, 15 m a.s.l.), on a Calcixerollic Xerochrepts soil, aimed at quantifying the effect of shading on chlorophyll (Chl) content, Chl fluorescence, photosynthesis and growth of subterranean clover. Four levels of photosynthetically active radiation reduction (from 0 % to 90 %) were tested on Trifolium brachycalycinum cv. ‘Clare’ and Trifolium subterraneum ecotype ‘Ragalna’. In both species shading progressively increased Fv/Fm, internal CO2 concentration, diffusive leaf resistance and specific leaf area (up to 8 %, 34 %, 18 % and 68 %, respectively), and decreased Chl content, Tmax, photosynthetic rate and plant dry weight (up to 9 %, 24 %, 79 % and 39 %, respectively). As plants aged, characteristic bell‐shaped trends were evident for photosynthetic parameters, with Fv/Fm increasing up until the onset of flowering, and thereafter declining. This implies that Fv/Fm may be a useful indicator of earliness in subterranean clover genotypes. The aboveground dry biomass response to shading was both genotype‐ and season‐dependent, but was predictable from the measurement of relative leaf Chl content. Moreover, our results suggest that an improvement in the interaction between host‐rhizobium may represent a major potential breeding target for enhancing subterranean clover tolerance to shading.

“…It has been used as a means to screen plants for heat tolerance (Yamada et al 1996, Ranney andRuter 1997). It is also a useful tool for screening durum and bread wheat for drought tolerance (Flagella et al 1994(Flagella et al , 1995, as a selection criterion in durum wheat for high grain yield (Araus et al 1998), and for the measurement of photochemical activity in cross-combination sugarcane (Zhang et al 2000).…”

Field experiments were conducted in Sicily (south Italy) to assess chlorophyll (Chl) fluorescence parameters in response of potato crop to nitrogen dose, to variation in genotype and in plant age, and to detect relationships between Chl content, fluorescence parameter F v /F m , and tuber yield. The experiment included five nitrogen doses (0, 10, 20, 30, and 40 g m -2 ) and four genotypes (Spunta, Sieglinde, Daytona, and Igea). Chl fluorescence parameters (initial fluorescence, F 0 , maximum fluorescence, F m , variable fluorescence, F v , F v /F m , T max (the time required to reach F m ), and Chl content were measured weekly between the appearance of the fifth and sixth leaves and the onset of plant senescence. A positive linear relationship was established between nitrogen supply and Chl content, F 0 , and T max . Nitrogen supply up to 10 g m -2 also had a positive effect on F m and F v , but above this rate it reduced F v /F m . Spunta had the highest Chl content, F m , F v , and F v /F m , but the lowest F 0 , whereas Sieglinde had the lowest Chl content, F v , F v /F m , and T max and the highest F 0 . The cvs. Igea and Daytona exhibited intermediate Chl fluorescence parameters. Chl content and T max decreased with increasing plant age, whereas F 0 , F m , and F v increased until complete canopy development and thereafter declined until crop maturity. Tuber and plant dry matter yield were significantly correlated with Chl content, F 0 , and T max . Thus Chl fluorescence and content detect differences in the response of potato to N supply, can discriminate between genotypes, predict plant age, and yield performance under field conditions.
