The objective of this research was to develop an appropriate tetrazolium methodology for viability and vigor evaluation of squash seeds. The following procedures were tested for preconditioning of the seeds: moistening in wet paper towel for 16 to 24h at 25°C; immersion in water for 15, 30 and 60 minutes at 40°C for tegument removal, and for 30 and 60 minutes for removal of the embryo surroundi...

Hutchinson-Gilford progeria syndrome (HGPS) is caused by de novo dominant point mutations of the genes encoding nuclear lamina proteins, leading towards premature aging. A protein sequence is subjected to mutations in nature which can affect the function and folding pattern of the protein by different ways. Mutations involved in HGPS were identified and were substituted in the seed sequence ret...

Chia (Salvia hispanica L.) is an edible seed that comes from an annual herbaceous plant, Salvia hispanica L. of mint family (Lamiaceae) (Figure 1). The shape of Chia seed is oval with 1 to 2mm in size, which may be black, grey or black spotted to white in colour. Chia means strength and the tiny seeds have been used as energy booster. Chia seeds can be used in the form of whole seeds, mucilage,...

This paper describes a simple and versatile method for growing highly anisotropic nanostructures of Pd, single-crystal nanobars bounded by {100} facets and single-crystal nanorods with their side surfaces enclosed by {100} and {110} facets. According to thermodynamic arguments, Pd atoms should nucleate and grow in a solution phase to form cuboctahedrons of spherical shape with their surfaces bo...

Increased cellular levels of reactive oxygen species are known to occur during seed development and germination, but the consequences in terms of protein degradation are poorly characterized. In this work, protein carbonylation, which is an irreversible oxidation process leading to a loss of function of the modified proteins, has been analyzed by a proteomic approach during the first stages of ...

Today in the wine industry, oenological tannins are widely used to improve wine quality and prevent oxidation in wine aging. With the development of tannin products, new oenological tannins are developed with many specific functions, such as modifying antioxidant effect, colour stabilization and aroma modifications. The aim of this work is to investigate effects of pre-fermentative addition of ...

Near infrared reflectance spectroscopy (NIRS), a non-destructive and rapid analytical method, was used to examine the possibility of replacing a method for the large-scale screening of tomato seed viability. A total of 368 tomato seed samples were used for development and validation of an NIRS calibration model. The accelerating aging method (98 ± 2% R.H., 40 ◦C) was employed for preparation of...

Abstract: Soybean has shown increasing performance in terms of yield recent years. However, despite this growth, the lack quality control and knowledge about effects nutritional status plants compromised germination vigor a significant proportion seeds. The aim study was to evaluate physiological seeds root growth soybean cultivated with boron (B) sources different solubilities incorporated int...

Abstract: The aim was to evaluate the effects of previous crop and top-dressing nitrogen fertilization on yield physiological sanitary quality common bean seeds. design used in randomized blocks a split-plot scheme, with four replications. plots were represented by three crops (sole maize, maize + Urochloa ruziziensis sole U. ruziziensis), preceding bean. subplots consisted N doses (urea) appli...
