Megjegyzések:Nanotechnology has been revolutionized penetrating all sectors in our life through the nanoscience as an essential science for a wide range of technologies. Amazing achievements resulted from this nanotechnology including all agricultural fields such as plant nutrition and crop productivity, energy sector, food sector, and plant biotechnology. A conjugation between plant biotechnology and nanotechnology has been produced an important science called plant bio-nanotechnology. Several fields have been invaded through different nanobiotechnology applications in agriculture including (1) the nanotechnology of encapsulated agro-chemicals, (2) the monitoring of different environmental stresses and crop conditions using nanobiosensors, (3) the improvement of crop production and ameliorating plants against diseases and (4) solution several environmental problems. The crop productivity also could be improved using some new agro-chemicals (e.g., nanofertilizers and nanopesticides). These agro-chemicals are very effective in delivering encapsulating nanomaterials and then enhancement the productivity of crops as well as the suppress plant pests and diseases and protecting the environment from pollution. On the other hand, nanoparticles could enter the food chain via different nano-agrochemicals or nano-processed foods. Therefore, many approaches including uptake of nanoparticles by plants, entry and bio-distribution of nanoparticles into the food chain are needed before using of different bionanotechnological tools in agro-production sector. Further new regulations should be created or re-built for new approaches in plant bionanotechnology. Therefore, this review will focus on our needs and risks in the plant nano-biotechnology.

Megjegyzések:During the past 10 years, exploiting engineered nanoparticles in agricultural sector has been rapidly increased. Nanoparticles are used to increase the productivity of different crops particularly under biotic and abiotic stresses. This study aims to test the ability of nanosilica (NS) to ameliorate the detrimental impact of Na+ with different concentrations on the seed germination and the growth of common bean seedlings. Five doses of Na+ have been prepared from NaCl, i.e., 1000, 2000, 3000, 4000, and 5000 mg L-1, and distilled water was applied as a control. Seeds and seedlings were treated with three different NS concentrations (100, 200, and 300 mg L-1). The results proved that Na+ concentrations had detrimental effects on all measured parameters. However, treating seeds and seedlings with NS improved their growth and resulted in higher values for all measurements. For instance, the addition of 300 mg L-1 NS leads to an increase of the final germination percentage,vigor index, and germination speed for seeds irrigated with 5000 mg Na+ L-1 by 19.7, 80.7, and 22.6%, respectively. Although common bean seedlings could not grow at the highest level of Na+, fortification seedlings with NS helped them to grow well under 5000 mg L-1 of Na+. An increase of 11.1 and 23.1% has been measured for shoot and root lengths after treating seedlings with 300 mg L-1 NS under irrigation with 5000 mg Na+ L-1 solutions, and also at the same treatment, shoot and root dry masses are enhanced by 110.9 and 328.0%, respectively. These results proved the importance of using NS to relieve the detrimental effects of Na+-derived salinity. This finding could be reinforced by low Na content which was measured in plant tissues after treating seedlings with 300 mg L-1 of NS.

Cím:Exogenous nanosilica improves germination and growth of cucumber by maintaining K+/Na+ ratio under elevated Na+ stress / Abdullah Alsaeedi, Hassan El-Ramady, Tarek Alshaal, Mohamed El-Garawani, Nevien Elhawat, Awadh Al-Otaibi
Dátum:2018
ISSN:0981-9428
Megjegyzések:The current work was aimed to elucidate the role of engineered nanosilica (SiNPs) particles to mitigate the damaging impacts of Na+-derived salinity on cucumber (Cucumis sativus) Beit Alpha variety by conducting in vitro experiments applying various Na+ concentrations i.e. 0, 1000, 2000, 3000, 4000 and 5000 mg L?1. By treating seeds and seedlings, respectively, of cucumber with SiNPs (0, 100, 200 and 300 ppm) and subsequent determination some germination and vegetative parameters as well as chemical analysis of seedlings, we verified that SiNPs succeeded to alleviate the detrimental effects of high Na+ salinity by increasing germination parameters and vegetative growth of cucumber seedlings. Even as little as 100 ppm of N-Si results in considerable improvement of seed germination and seedlings growth of cucumber compared to the control, while 200 ppm was optimal among the doses tested. At 5000 mg Na+ L?1, applying SiNPs with 200 ppm increased final germination percentage by 101% over control, vigor index by 101%, germination rate index by 116%, germination index by 110%, fresh mass by 13%, K+/Na+ ratio by 77%, shoot dry mass by 384%, root dry mass by 304% and plant height by 70%. The results mentioned in this paper obviously outline the large practical relevance of SiNPs and imply that applying of SiNPs for cucumber seeds and seedlings under high Na+-derived salinity enhances germination and growth as a result for decreasing Na+ uptake and sequentially improves high K+/Na+ ratio.

Cím:Silica nanoparticles boost growth and productivity of cucumber under water deficit and salinity stresses by balancing nutrients uptake / Abdullah Alsaeedi, Hassan El-Ramady, Tarek Alshaal, Mohamed El-Garawany, Nevien Elhawat, Awadh Al-Otaibi
Dátum:2019
ISSN:0981-9428 1873-2690
Megjegyzések:The role of amorphous silica nanoparticles (SiNPs) in enhancing growth and yield of cucumber under water deficit and salinity stresses was assessed. A field experiment under greenhouse conditions was established using 4 different levels of SiNPs (100, 200, 300 and 400 mg kg(-1)) and 3 different watering regimes calculated based on crop evapotranspiration (ET,) (100, 85 and 70% of ETc). Electrical conductivity and sodium adsorption ratio of irrigation water were 1.7 dS m(-1) and 4.63 respectively. The results revealed that SiNPs improved growth and productivity of cucumber regardless of quantity of supplied water; however, the greatest increase corresponded to irrigating cucumber at the rate of 85% of ETc. Applying SiNPs at rate of 200 mg kg(-1) showed the greatest increase specially when cucumber plants received 85% of their ETc causing an increase of 20, 51 and 156% in plant height, chlorophyll and fruit yield, respectively, compared to untreated plants. These increases could be due to alerting nutrient uptake as SiNPs clearly increased contents of nitrogen (by 30%), potassium (by 52, 75 and 41% in root, stem and leaf, respectively) and silicon (by 51, 57, 8 and 78% in root, stem, leaf and fruit, respectively). Otherwise, same treatment reduced sodium uptake by 38, 77 and 38% in root, stem and leaf, respectively; consequently, potassium-sodium ratio increased by 149, 735 and 127% in root, stem and leaf, respectively. The significant role of SiNPs in mitigating water deficit and salinity stresses could be referred to high silicon content found in leaf which regulates water losses via transpiration. Also, high K content found in roots of cucumber helps plants to tolerate abiotic stresses as a result of maintaining ion homeostasis and regulating the osmotic balance as well as controlling stomatal opening which helps plants to adapt to salinity and water deficit stresses.

Megjegyzések:Brown juice is a byproduct of fractionated green biomass during leaf protein isolation. It represents approximately 45%?50% of the total pressed fresh biomass. Disposal of brown juice is a serious issue in leaf protein production due to its high biological oxygen demand and carbohydrates content. The current study aimed to find a possible potential use of brown juice. Therefore, chemical and biochemical properties of brown juice?derived from alfalfa green biomass?were determined before and after fermentation by lactic acid bacteria. Additionally, the growth stimulation potential of fermented brown juice on plumed cockscomb (Celosia argantea var. plumose 'Arrabona') plants were tested. Celosia seedlings were sprayed at different rates of fermented brown juice (i.e., 0.5%, 1%, 2.5%, 5%, and 10%) and tap water was applied as control. The results revealed that lactic acid bacteria successfully enhanced the stabilization of brown juice via reducing sugars content and increasing organic acids content. After fermentation, contents of glucose monomers were 15 times lower; while concentrations of lactic and acetic acids increased by 7- and 10-fold, respectively. This caused a reduction in the pH of fermented brown juice by 13.9%. Treating Celosia plants at lower rates of fermented brown juice (up to 1.0%) significantly induced their growth dynamics and antioxidant capacity. Higher values of vegetative parameters were measured in treated plants compared to control. The brown juice treatments caused significant changes in histological parameters as well. The activity of catalase and peroxidase increased in plants that received fermented brown juice especially at low rates. Moreover, an increase in water-soluble protein and phenol was measured in different tissues of plants sprayed with fermented brown juice. Malondialdehyde content was lowered in treated plants compared to control. Fermented brown juice at high rates slightly reduced the amount of photosynthetic pigments; however, this reduction was not reported for low rates of fermented brown juice. These results surely illustrate the potential use of fermented alfalfa brown juice as a growth stimulator for crops particularly at rates below 2.5%.

Megjegyzések:Selenium, the beneficial or quasi-essential element to higher plants, is an essential micronutrient for animals and humans as well as lower plants. in several countries around the world, about one billion of people are se-deficient and counteract this problem, e.g., brazil, thailand, china and egypt due to the low inherent se concentration in soils. therefore, different se forms have been used in different crops using foliar and soil application as well as seed priming to increase the se content in the edible parts of these crops. due to its physiolocial roles in higher plants, se has been used in counteracting various abiotic stresses including chilling, freezing, heat, drought, salinity, uv-b and heavy metals. concerning se and its interactions with some nutrients like cu, mo, zn and iodine, a very few studies have been published, so further studies are needed. on the other hand, nano-se and its roles in plant physiology under different abiotic stresses still also need further researches. therefore, this review will focus on the physiological importance of se and nano-se for higher plants under abiotic stresses as well as the interaction of se with some nutrients including cu, mo, zn and iodine and some heavy metals such as As, Sb, Cd, Cr, Hg and Pb.
