“…CF could be affected by a wide number of both biotic and abiotic factors (e.g., drought, heat, flooding, temperature variation, parasitization, etc.) (Dong et al, 2020;Duarte et al, 2020;Zhou et al, 2020;Zhuang et al, 2020), which makes the evaluation of the mode of action of natural molecules quite impossible because of the overlapping of stressing conditions, which makes impossible to attribute the observed effects to the molecule assayed. Therefore, it is strongly suggested to perform experiments in completely controlled conditions using phytotrons and cropping plants hydroponically or on inert substrates enriched with nutrients and carbon sources (Graña et al, 2013b(Graña et al, , 2016Araniti et al, 2017c).…”

Imaging of chlorophyll a fluorescence (CFI) represents an easy, precise, fast and non-invasive technique that can be successfully used for discriminating plant response to phytotoxic stress with reproducible results and without damaging the plants. The spatio-temporal analyses of the fluorescence images can give information about damage evolution, secondary effects and plant defense response. In the last years, some studies about plant natural compounds-induced phytotoxicity have introduced imaging techniques to measure fluorescence, although the analysis of the image as a whole is often missed. In this paper we, therefore, evaluated the advantages of monitoring fluorescence images, presenting the physiological interpretation of different possible combinations of the most relevant parameters linked to fluorescence emission and the images obtained.

“…A non-destructive technique to determine the content of chlorophyll a in the seed coat is based on measuring of the CF signals from intact seeds. This method is a highly sensitive and rapid and has been used in seeds of various plant species such as cabbage (Brassica oleracea L.) (Jalink et al, 1998), tomato (Solanum lycopersicum L.) (Jalink et al, 1999), cucumber (Cucumis sativus L.) (Jing et al, 2000), barley (Hordeum vulgare L.) (Konstantinova et al, 2002), carrot (Daucus carota L.) (Groot et al, 2006), soybean (Glycine max L.) (Cicero et al, 2009), cantaloupe (Cucumis melo L.) (Wilson et al, 2014) and pepper (Capsicum annuum L.) (Kenanoglu et al, 2013;Kenanoglu et al, 2016).…”

In this study, we assessed the content of chlorophyllaandb, β-carotene and lutein in seeds of carrot, celery, dill, parsley and parsnip commercial varieties by spectrophotometric method. It was determined that the content of chlorophyllawas higher than chlorophyllband both differed significantly between plant species and varieties. The highest amounts of chlorophylla, chlorophyllb, β-carotene and lutein were detected in parsley “Olomoucka dlouha”. The lowest amounts of chlorophylla, chlorophyllb, β-carotene and no lutein were detected in celery “Nuget”, however, very low amount of lutein was detected in the parsley cultivars “Atika” and “Orbis”. The content of β-carotene was higher than that of lutein in most varieties. The individual pigment contents were compared to seed quality parameters such as standard laboratory germination and seedling emergence. Negative correlation between energy of germination and pigments and positive correlation between seedling emergence and pigments in the parsnip and parsley varieties was observed. Determination the content of pigments and correlations observed the possibility to use spectrophotometry to evaluate the pigments present in the seeds as an indicator of seed quality.

“…Postharvest technologies cannot reverse such damage but are able to remove immature, aged and damaged seeds, thereby upgrading seed lots. Methods to detect seed maturity specifically using chlorophyll fluorescence (high levels are associated with less mature seeds) can be used to upgrade seed quality in a number of species (Jalink et al, 1998;Kenanoglu et al, 2015;Bello and Bradford, 2021). Variation in seed maturity of indeterminate crops is a clear example of seed lots that contain multiple subpopulations (Still and Bradford, 1998), is the foundation of standard seed conditioning equipment using seed size, shape, density, color or other physical characteristics to fractionate seed lots.…”

Achieving rapid and uniform stand establishment in crops requires a combination of high-quality seeds and appropriate environmental conditions. In particular, temperature and soil moisture (or water potential) are the major factors influencing germination in the field. In this chapter, we focus on the application of population-based threshold (PBT) models to characterize seed germination time courses and how environmental and technological inputs influence them. Viewing seed quality as a product of the behavior of populations of individual seeds is critical for understanding the causes and consequences of poor performance. Quantitatively characterizing seed population features enables their use in seed sorting and seed enhancement, and provides phenotypes for use in research, breeding, conservation and restoration. We believe that PBT models are essential tools to enable full utilization of new advances in seed technology to improve seed quality and enable successful stand establishment in agriculture or in natural settings.
