[...]of its importance, wheat has been widely studied from the perspective of genetic aspects and breeding programs (Gao et al, 2021; Govta et al, 2022), physiological aspects (Mohan and Gupta, 2015), soil fertilization and plant nutrition aspects (Hirzel et al, 2022; Jat et al, 2022), productivity elements (Datcu et al, 2019; Jat et al, 2022), production quality, but also in relation to their interactions (Govta et al, 2022; Jat et al, 2022). The content of photosynthetic pigments is important in relation to the photosynthesis process, in order to convert solar energy into biochemical energy and specific metabolic compounds (Lu et al, 2001; Liu et al, 2020). The content of photosynthetic pigments in wheat varies in relation to the genotype (Javed et al, 2022), environmental factors and vegetation conditions (Xiong et al, 2015), the position of the leaves on the plant (may much studied flag leaf) (Roy et al, 2021; Yang et al, 2022), with fertilization and plant nutrition status (Zhang et al, 2021), water regime (Yang et al, 2022), the state of plant health (Cai et al, 2021), vegetation stages of plants (Zhang et al, 2009; Li et al, 2022), stress factors (Roy et al, 2021), but also interactions of factors, such as "genotype x environment" or "genotype x environment x technological inputs". [...]it was found in some studies the variation of the spatial distribution of the photosynthetic pigments (eg chlorophyll) in the leaves, in relation to the geometry of the leaf (especially the length) but also with various other factors (Borsuk and Brodersen, 2019; Huang et al, 2023).
