Antioxidant Characteristics

In the germination of seeds an increase in their nutritional value has been observed, such as the increase in protein and micronutrients. It has been found that continuous intake of some types of sprouts helps prevent certain chronic diseases, such as colon cancer, Alzheimer's, among others. The objective is to evaluate the physicochemical and antioxidant characteristics of alfalfa, chia, lentil and broccoli sprouts. For the seed germination process a container was placed with water and covered with a cloth so that a firm surface remained and on this the seeds were placed. The seeds were sprayed with water twice a day until favorable growth was noted. Broccoli sprouts obtained the highest values of DPPH radical inhibition and polyphenol content. The physicochemical and antioxidant characteristics vary according to germination days.

Comparison Of The Results

Relevance. Evaluation of nutritional value of seeds of agricultural crops is considered to be highly significant for revealing new sources of antioxidants for humans.Material. The aim of the present investigation was antioxidant status and selenium accumulation levels by chicory seeds (13 cultivars) and comparison of the results with antioxidants status of seeds of other root vegetables: celery (5 cultivars), parsley (2 cultivars), parsnip (3 cultivars) and carrot (7 cultivars).Results. Among agricultural crops studied chicory was characterized by 3-4 higher levels of selenium accumulation by seeds and relatively low total antioxidant activity and polyphenol content. Anomalously high protein content in chicory seeds may explain the efficiency of selenium accumulation while relatively low antioxidant activity may be connected with lower levels of essential oil. Direct correlations between polyphenol content and total antioxidant activity were demonstrated for carrot (r=+0.924; P<0.01) and chicory (r= 0.803; P<0.01) seeds.

Antioxidant Characteristics

Bee products have been used since ancient times both for their nutritional value and for a broad spectrum of therapeutic purposes. They are deemed to be a potential source of natural antioxidants that can counteract the effects of oxidative stress underlying the pathogenesis of many diseases. In view of the growing interest in using bioactive substances from natural sources to promote health and reduce the risk of developing certain illnesses, this review aims to update the current state of knowledge on the antioxidant capacity of bee products such as honey, pollen, propolis, beeswax, royal jelly and bee venom, and on the analytical methods used. The complex, variable composition of these products and the multitude of analytical methods used to study their antioxidant activities are responsible for the wide range of results reported by a plethora of available studies. This suggests the need to establish standardized methods to more efficiently evaluate the intrinsic antioxidant characteristics of these products and make the data obtained more comparable.

Abstract Ingestion of seeds by vertebrates may influence seed germination and dispersion. However the mechanisms responsible by these effects and the importance of turtles in these interactions are still poorly understood. This study aims to evaluate how Chelonoidis carbonarius influences the germination process of Leucaena leucocephala using an experiment conducted at the Federal University of Ceará, Fortaleza-CE, Brazil, that simulates the passage of the seeds of this plant through the digestive tract of C. carbonarius: stomach acidic condition and seeds sown in feces. We demonstrated that sowing the seeds in feces of Chelonoidis carbonarius has a negative effect on the germination of Leucaena leucocephala, decreasing the germination speed index of the seeds, while the acidic conditions have a neutral one. This study is a first attempt to understand how turtles and tortoises may influence the seed germination, and the implications of these findings in natural environments deserve further investigations.

Abstract: Nitric oxide (NO) can act in biochemical pathways of the germination process; however, there is little information about how it acts on the performance of pea seeds. The aim of this study was to evaluate the physiological and biochemical effects of NO on pea seed germination and vigor. Pea seeds cv. Itapuã 600 obtained from three seed lots with different levels of physiological quality were sown in a substrate moistened with water (control) or sodium nitroprusside (SNP) solution, a NO donor (50 μM), to assess germination, vigor, activity of antioxidant enzymes, reactive oxygen species, lipid peroxidation, and amylase activity. NO application does not alter pea seed germination, but it increases vigor. It is more effective in seeds with lower physiological potential. In addition, NO leads to reduction in oxidative stress, favors the translocation of reserves to the embryo, and has potential for use in the treatment of pea seeds to increase seed vigor.

The Impact

Abstract The aim of this study was to compare the nutritional and use value of berries grown in organic and conventional systems. The polyphenol content, fruit colour and firmness, and yeast, mould, and mycotoxin contents were assessed in blueberry fruit freshly harvested and stored for 8 weeks in controlled conditions (CA: CO2-12%; O2-1.5%, temperature 1.5 °C). The Shannon–Wiener diversity index was comparable in both systems and was lower for mould in organic fruit than in conventional fruit. Mycotoxins (deoxynivalenol, zearalenone) were found only in organic fruits. The optimal mineral content and pH of the soil allowed the cultivation of blueberry in accordance with organic standards. The storage of highbush blueberry fruit in CA cold storage for 8 weeks resulted in a slight deterioration in fruit quality and polyphenol content. The lower nutritional value of these fruits is compensated by the lack of pesticides and artificial fertilizers residues. The use of fungicides in conventional cultivation reduces the population of sensitive fungi and therefore reduces the contamination of fruits with mycotoxins.

Level Of Significance

The present investigation focused on the effects of plant and seed diffusates of Parthenium hysterophorus L. on seed germination of Raphanus sativus L. Level of glucose in germinating seeds as an indirect measure of amylase activity was estimated. About 91.66% viable seed of Raphanus sativus were treated in different concentrations of rhizospheric soil diffusates (PD) and germinating seed diffusates (SD) of Parthenium hysterophorus. Both diffusates were found effective to retard and minimize the germination of Raphanus seeds. The maximum inhibition for both cases was found at 100 % concentrations of the diffusates. The correlation analysis revealed the correlation factor - 0.784 between PD concentrations and Raphanus seed germination and that of - 0.889 between SD concentrations and Raphanus seed germination with 5% level of significance. This indicated that the increase in concentrations played negative role in germination process of Raphanus seeds. The results were interpreted in terms of the possible roles of "Parthenin", a sesquiterpene-lactone which is known to be present in Parthenium hysterophorus.

Germination Process

The purpose of the experiment was to highlight the germination of sunflower seeds affected by the presence of saline stress and the identification of tolerant genotypes. The biological material was represented by sunflower cvs. (Helianthus annuus L.): Coril, Select, Santiago and Fundulea-206. To simulate the saline conditions, germination solutions of sodium chloride (NaCl) were used with concentrations corresponding to the osmotic pressures -6 and -10 atm and the control seed hydration was performed with distilled water. Determination of seed germination, growth of seedling, percentage of plumules dry matter, chlorophyll content and free proline were performed. The experimental data obtained suppose the existence in the assimilation apparatus of sunflowers seedling subjected to stress a competitive chlorophyll/free proline biosynthesis processes. The experimental results regarding the effect of salinity on seed germination and seedling growth revealed important differences between genotypes. The radicle growth in the germination process were strongly affected by saline excess, with significant differences between cultivars. Saline stress results in significant reductions in the amount of chlorophyll, and high levels of free proline. It can be observed that with the increase of the stress level the percentage of the dry matter increases, indicating an accentuated water deficit.

Insight Into

AbstractSeed germination is a crucial event in a plant's life cycle. Because temperature and water availability are important regulators of seed germination, this process will likely be influenced by global warming. Insight into the germination process under global warming is thus crucial, and requires the study of a wide range of water availability and temperature conditions. As hydrothermal time (HTT) models evaluate seed germination for any combination of water potential and temperature, they can be suitable to predict global warming effects on seed germination. We studied the germination characteristics of the high Andean endemic tree speciesPolylepis besseri(Rosaceae), using HTT models. We were especially interested in the potential effects of global warming on seed germination. Assembly of HTT models forP. besseriwas fairly straightforward due to the lack of a seed dormancy mechanism. The models allowed prediction ofPolylepisgermination under constant and alternating temperatures. Initially, a global warming induced increase in the field minimum and mean temperature will increaseP. besserigermination, but as maximum temperatures rise above the optimum temperature for the species, seed germination will become jeopardized. Effects of global warming on seed germination are currently considerably underexplored. HTT models prove to be useful tools to study a plant species' general germination characteristics, and how they may become affected under global warming. For the endemic mountain tree speciesP. besseri, we predict an increase, followed by a decrease of seed germination under global warming.

Doubled haploids (DH) were obtained from two interspecific hybrids between Brassica napus and Brassica rapa. Seeds of doubled haploid plants differed in colour and size. The hybridity of the obtained doubled haploid is shown using genomic in situ hybridization (GISH) analysis. Evaluation of drought tolerance during seed germination on PEG-6000 showed the advantage of doubled haploid plants of interspecific hybrids over the parent cultivars. The oil from seeds of doubled haploid plants showed good nutritional value.
