“…At the same time, they reduce the water content in the soil in the immediate vicinity of the seed, which may cause an increase in the mechanical resistance of the radicle (Hadas, 2004). The same explanation of the higher amount of soil around pelleted seeds, in comparison to naked seeds, was presented by Blunk et al (2017). It was observed during the study that the pelleted seeds provided by company B swelled three times as much as the seeds obtained from company C. Similarly, the water content in the pellets of these seeds differed by a factor of two.…”

Effects of the physicochemical properties of pellets on the germination of pelleted sugar beet seeds

The effects of the physicochemical characteristics of pellets, when applied to sugar beet seeds originating from ten seed companies, on the germination of pelleted seeds were assessed. The most significant factor was the force necessary to break the pellet, which was found to positively correlate with pellet's abrasion resistance, and negatively with pellet's water resistance. Pellets dissolved in water, characterized by low water resistance, negatively affected germination under the conditions of excess water in the filter paper. A low water potential of pellets inhibited seed germination, particularly with the shortfall of water in the germination medium. The water flow between the pellet and the pericarp was of much importance for germination. Under the conditions of the shortfall and excess of water in the germination medium, the physicochemical properties pellets had a greater effect on the drawing of water, and on the water flow between the pellet and the seeds, than under the optimum moisture conditions. Organic pellets were characterized by a greater ability to absorb water than mineral or organic-mineral pellets. The pellets varied in their chemical composition, with the greatest variation (over ninety-fold) relating to pellet's copper content. The following values exhibited low variety: Zn, Mn, and Pb. It can be concluded that pellet's cracking force and water resistance are the basic parameters of pellet quality, and the swelling ability of pellets is determined by their organic or monaural composition.

“…A high swelling ability of pellets improves the seedsoil contact. Blunk et al (2017) suggested that the sugar beet seed-soil contact was very low. In our research, differences in pellet's swelling ability were probably caused by the use of materials of different types and quality for pelleting.…”

“…The fruit coat represents a point of entry for water but also restricts the hydration rate to a certain degree as rapid water uptake may lead to cellular damage [29]. The general assumption is that seeds swell during the imbibition process which is followed by a shrinkage of the soil matrix due to water extraction, and also compaction near the seed surface induced by the swelling [30], although recent imaging assessments under laboratory conditions have shown this is not always the case [31]. The extent of swelling is determined by the presence of a pericarp as it swells faster in the initial stages of water uptake compared to embryonic sections, i.e.…”

Water uptake into seeds is a fundamental prerequisite of germination and commonly influenced by commercial seed enhancement technologies. The effect of fruit orientation and contrasting pelleting materials on germination and biological performance of sugar beet was assessed. The results indicated there was orientation dependent fruit shrinkage of 37% for the operculum side supplied by moisture compared to 4% for the basal pore side. The expansion rate of 5% compared to the original size, which was also observed for non-shrinking seeds, indicated this was a temporary effect. This behaviour has importance for the application pelleting materials to seeds. Pellets composed of materials exhibiting low levels of swelling act as a water distribution layer which increased germination rates. Careful selection of pelleting material is crucial as it has direct implications on germination speed and subsequent establishment rates.

“…present a nice review of relevant applications [7]. Detection of the plant seed directly is usually not a primary study goal, but new methods are emerging focusing on seed-soil contact areas [45]; in some studies the seed volume is accounted for in the model parameters when estimating root volumes and detecting first-order roots [17], and plants are usually scanned after the first 7-8 days of planting [46].…”

Abstract:Scanning technologies based on X-ray Computed Tomography (CT) have been widely used in many scientific fields including medicine, nanosciences and materials research. Considerable progress in recent years has been made in agronomic and plant science research thanks to X-ray CT technology. X-ray CT image-based phenotyping methods enable high-throughput and non-destructive measuring and inference of root systems, which makes downstream studies of complex mechanisms of plants during growth feasible. An impressive amount of plant CT scanning data has been collected, but how to analyze these data efficiently and accurately remains a challenge. We review statistical and computational approaches that have been or may be effective for the analysis of 3D CT images of plant roots. We describe and comment on different approaches to aspects of the analysis of plant roots based on images, namely, (1) root segmentation, i.e., the isolation of root from non-root matter; (2) root-system reconstruction; and (3) extraction of higher-level phenotypes. As many of these approaches are novel and have yet to be applied to this context, we limit ourselves to brief descriptions of the methodologies. With the rapid development and growing use of X-ray CT scanning technologies to generate large volumes of data relevant to root structure, it is timely to review existing and potential quantitative and computational approaches to the analysis of such data. Summaries of several computational tools are included in the Appendix.
