SUMMARY Successful crop production depends initially on the availability of high-quality seed. By 2050 global climate change will have influenced yields, but these changes affect seed quality? The present review examines effects elevated carbon dioxide (CO 2 ) and temperature during three quality components: mass, germination vigour. In response to CO , mass has been reported both increase decrease in C 3 plants, not 4 plants. Increases are greater legumes than non-legumes, there is...

Abstract Multispectral imaging is a new technology that being deployed to assess seed quality parameters. Examples of applications in the detection and identification fungi on seeds are presented, together with an example used for maturity determination sugar beet seed. Results from multispectral compared reference methods, high correlation found. Applications technique varietal discrimination insect damage also presented. There need non-destructive, reliable fast techniques, it concluded...

The purpose of this study was to highlight the use multispectral imaging in seed quality testing castor seeds. Visually, 120 seeds were divided into three classes: yellow, grey and black Thereafter, images at 19 different wavelengths ranging from 375–970 nm captured all Mean intensity for each single extracted images, a significant difference between colour classes observed, with best separation near-infrared wavelengths. A specified feature (RegionMSI mean) based on normalized canonical...

The seed is the carrier of genetic improvements brought about by modern plant breeding, and production carried out in accordance with certification systems to guarantee consistent high quality. In forage legumes, breeding efforts are primarily related vegetative development plant, although commercial success an agronomically superior cultivar dependent on a reliable supply competitively priced seed. three most important alfalfa (Medicago sativa L.), white clover (Trifolium repens red...

Abstract Salt stress is a major yield‐limiting factor in crops by reducing nutrient uptake and plant growth. Under salt stress, decreased water results imbalance plants. In addition, at high pH saline conditions, solubility of minerals also reduced leading to low availability certain nutrients. Perspectives overcome these limitations Zn seed priming were studied with maize plants exposed NaCl as stress. Maize seeds primed for 24 hr deionized 4 m SO ·7H 2 O solution (ZnP) subsequently...

To assess seed germination parameters and identifying tolerant varieties, seeds of nine tall fescue varieties (Festuca arundinacea Schreb.) were germinated under various salinity levels for 14 days. Tall is considered 'moderately tolerant' to stress, but our study revealed a remarkable diversity among the tested varieties. Armani, Essential, Fatcat, Starlett found reach same final (>90%), irrespective NaCl concentration up 15 ds m−1 NaCl; Asterix Meandre expressed lower highest level (>75%);...

Abstract Background The use of non-destructive methods with less human interference is great interest in agricultural industry and crop breeding. Modern imaging technologies enable the automatic visualization multi-parameter for characterization biological samples, reducing subjectivity optimizing analysis process. Furthermore, combination two or more techniques has contributed to discovering new physicochemical tools interpreting datasets real time. Results We present a method seed quality...

Food security depends on seed and the international industry must be able to continue deliver quantities of quality required for this purpose. Abiotic stress resulting from climate change, particularly elevated temperature water stress, will reduce yield quality. Options adapt change include moving sites production, changing sowing date, development cultivars with traits which allow them conditions. However, ability growers make these changes is directly linked system. In formal system...

Perennial ryegrass (Lolium perenne L.) produces high levels of fructans as a mixture oligomers with different degrees polymerization (DP). The present study describes the analysis compositional changes in full spectrum fructan oligomers, distribution between above ground biomass (top) and roots, transcription candidate genes involved metabolism during cold acclimation perennial variety 'Veyo' ecotype 'Falster' from distinct geographical origins. We observed composition induction low-DP...

The application of adequate nitrogen (N) fertilizers to grass seed crops is important achieve high yield. Application N will inevitably result in over-fertilization on some fields and, concomitantly, an increased risk adverse environmental impacts, such as ground- and/or surface-water contamination. This study was designed estimate the status two crops: red fescue (Festuca rubra L.) and perennial ryegrass (Lolium perenne using images captured with unmanned aerial vehicle (UAV) mounted...

The objective of seed testing is to provide high-quality seeds in terms high varietal identity and purity, germination capacity, health. Across the industry, it widely acknowledged that quality assessment needs an upgrade improvement by inclusion faster more cost-effective techniques. Consequently, there a need develop apply new techniques alongside classical methods, increase efficiency, reduce analysis time, meet stakeholders testing. Multispectral imaging (MSI) near-infrared spectroscopy...

Activation of numerous protective mechanisms during cold acclimation is important for the acquisition freezing tolerance in perennial ryegrass (Lolium perenne L.). To elucidate molecular two genotypes ('Veyo' and 'Falster') from distinct geographical origins, we performed transcriptome profiling using RNA-Seq. We cold-acclimated plants both controlled conditions a period 17 days isolated Total RNA at various time points high throughput sequencing Illumina technology. RNA-seq reads were...

The pericarp of monogerm sugar beet seed is rubbed off during processing in order to produce uniformly sized seeds ready for pelleting. This process can lead mechanical damage, which may cause quality deterioration the processed seeds. Identification damage and classification severity injury important currently time consuming, as visual inspections by trained analysts are used. study aimed find alternative assessment methods evaluating a machine vision technique five types Multispectral...

The effects of the number seeds in a training sample set on ability to predict viability cabbage or radish are presented and discussed. supervised classification method extended canonical variates analysis (ECVA) was used develop model. Calibration sub-sets different sizes were chosen randomly with several iterations using spectral-based selection algorithms DUPLEX CADEX. An independent test validate developed models. results showed that 200 optimal calibration for both data....

Molecular identification of fungal taxa commonly transmitted through seeds sorghum in Western Africa is lacking. In the present study, farm-saved seeds, collected from four villages Northern Burkina Faso, were surface sterilized and distribution DNA seven-day-old seedlings was analyzed by 18S ribosomal (rDNA) amplicon sequencing. More than 99% rDNA found to originate ascomycetes. The ascomycetes at species level subsequently barcoding ITS2 rDNA. Eighteen Operational Taxonomic Units (OTUs)...

Abstract Background Recent declines of honeybees and simplifications wild bee communities, at least partly attributed to changes agricultural landscapes, have worried both the public scientific community. To understand how managed bees respond landscape structure it is essential investigate their spatial use foraging habitats. However, such studies are challenging since behaviour differs between species can be highly dynamic. Consequently, necessary data collection laborious using...

Because of the difficulties in obtaining homogenous germination spinach seeds for baby leaf production, possibility using partial least squares discriminant analysis (PLS‐DA) on features extracted from multispectral images was investigated. The objective has been to discriminate between different seed sizes, as well predict ability and germ length. Images 300 including small, medium, large were taken, examined PLS‐DA loadings plots used reduce multidimensional image a few important features....

Abstract Maximum perennial ryegrass seed production potential is substantially greater than harvested yields with representing only 20% of calculated potential. Similar to wheat, maize and other agriculturally important crops, yield highly dependent on a number interacting components. This research was performed apply describe path analysis components in relation yields. Utilising extensive which included subdividing reproductive inflorescences into five size categories, undertaken assuming...
