Protective role of Ascophyllum nodosum seaweed biomass conjugated organic minerals as therapeutic nutrients to enhance tomato plant grown under salinity stress

Biomass Conversion and Biorefinery (2023)

Mohamed S. Attia Amer M. Abdelaziz Salah M. Elsayed M. Osman M. Ali

Abstract Climate changes and stresses negatively affected the physiological processes inside plant cells, which led to a clear imbalance in the global diet. In both irrigated and non-irrigated areas, salinity is one of the principal abiotic factors influencing plant growth and production, especially in crop plants. The present experiment was designed to evaluate two types of foliar feeding as anti-salt stress by measuring stress tolerant and antioxidant levels. Foliar feedings, Gluamin Cu, and Ascophyllum nodosum (WeGrow Special) were used as therabutic nutrients and stress raisers on plants irrigated with saline solution (150 mmol) and others irrigated with tap water. After 70 days of plant life, morphological characteristics, plant pigments, osmosis levels, phenols, and antioxidant enzyme activity were measured as indicators of plant recovery from stress damage. Measurements of vegetative growth, photosynthesis, sugars, and protein content decreased significantly in stressed plants. On the contrary, the level of proline, phenol, malondialdehyde, hydrogen peroxide, and sodium (Na + ) and the activity of antioxidant enzymes increased compared to non-stressed plants. The beneficial impacts of the foliar feedings (Gluamin Cu and WeGrow Special) have been broadened to increase all growth parameters, photosynthetic pigments, proline, phenol, and enzyme activities, in both unstressed and stressed plants in comparison to control. Interestingly, the harmful impact of salinity on tomato plants was significantly decreased and it can be evident from reduced MDA and H 2 O 2 levels. The results indicated that Gluamin Cu at a concentration of 3 cm L −1 foliar was the best treatment in increasing shoot length by 18.75%, root length by 51.8%, number of leaves by 31.5%, chlorophyll A by 98.9% and chlorophyll B by 47.6%, proline 12.6%, peroxidase by 39.6%, polyphenol oxidase by 14.29%, super oxide dismutase by 16.4%, and catalase by 54.9% in stressed plants compared to the stressed control. These results indicated that the use of any of the foliar nutrients (Gluamin Cu and WeGrow Special) considered to raise the salt stress in the plant and improve its morphological characteristics and metabolic processes inside the cells, and thus it can be used and applied commercially as environmentally friendly anti-salt stress.

Impact of Foliar Application of Chitosan Dissolved in Different Organic Acids on Isozymes, Protein Patterns and Physio-Biochemical Characteristics of Tomato Grown under Salinity Stress

Plants (2021)

Mohamed S. Attia M. Osman A. Mohamed Hany Mahgoub Mohamed O. Garada

In this study, the anti-stress capabilities of the foliar application of chitosan, dissolved in four different organic acids (acetic acid, ascorbic acid, citric acid and malic acid) have been investigated on tomato (Solanum lycopersicum L.) plants under salinity stress (100 mM NaCl). Morphological traits, photosynthetic pigments, osmolytes, secondary metabolites, oxidative stress, minerals, antioxidant enzymes activity, isozymes and protein patterns were tested for potential tolerance of tomato plants growing under salinity stress. Salinity stress was caused a reduction in growth parameters, photosynthetic pigments, soluble sugars, soluble proteins and potassium (K+) content. However, the contents of proline, ascorbic acid, total phenol, malondialdehyde (MDA), hydrogen peroxide (H2O2), sodium (Na+) and antioxidant enzyme activity were increased in tomato plants grown under saline conditions. Chitosan treatments in any of the non-stressed plants showed improvements in morphological traits, photosynthetic pigments, osmolytes, total phenol and antioxidant enzymes activity. Besides, the harmful impacts of salinity on tomato plants have also been reduced by lowering MDA, H2O2 and Na+ levels. Chitosan treatments in either non-stressed or stressed plants showed different responses in number and density of peroxidase (POD), polyphenol oxidase (PPO) and superoxide dismutase (SOD) isozymes. NaCl stress led to the diminishing of protein bands with different molecular weights, while they were produced again in response to chitosan foliar application. These responses were varied according to the type of solvent acid. It could be suggested that foliar application of chitosan, especially that dissolved in ascorbic or citric acid, could be commercially used for the stimulation of tomato plants grown under salinity stress.

Strategy of Salt Tolerance and Interactive Impact of Azotobacter chroococcum and/or Alcaligenes faecalis Inoculation on Canola (Brassica napus L.) Plants Grown in Saline Soil

Plants (2021)

Arafat Abdel Hamed Abdel Latef Amal M. Omer Ali A. Badawy M. Osman Marwa Ragaey

A pot experiment was designed and performed in a completely randomized block design (CRBD) to determine the main effect of two plant growth-promoting rhizobacteria (PGPR) and their co-inoculation on growth criteria and physio-biochemical attributes of canola plants (Brassica napus L.) plant grown in saline soil. The results showed that inoculation with two PGPR (Azotobacter chroococcum and/or Alcaligenes faecalis) energized the growth parameters and photosynthetic pigments of stressed plants. Moreover, soluble sugars’ and proteins’ contents were boosted due to the treatments mentioned above. Proline, malondialdehyde (MDA), and hydrogen peroxide (H2O2) contents were markedly declined. At the same time, antioxidant enzymes, viz. superoxide dismutase (SOD), ascorbate peroxidase (APX), and peroxidase (POD), were augmented due to the inoculation with Azotobacter chroococcum and/or Alcaligenes faecalis. Regarding minerals’ uptake, there was a decline in sodium (Na) and an increase in nitrogen (N), potassium (K), calcium (Ca), and magnesium (Mg) uptake due to the application of either individual or co-inoculation with the mentioned bacterial isolates. This study showed that co-inoculation with Azotobacter chroococcum and Alcaligenes faecalis was the most effective treatment and could be considered a premium tool used in facing environmental problems, especially saline soils.

The aim of this study was to investigate the efficiency test of a laboratory scale of pulsed electric field (PEF) device, on strawberry juices treated in a batch system. strength was (18.5 kV/cm for 500 µs at 100 Hz) for 60 sec. or 90 seconds as alternative physical and non-thermal method compared with those of thermal traditional method of pasteurization used Indirect heating by double jacket suit at (90оC / 5 min) and unprocessed juice (Fresh juice) as a reference (Control) was studied in terms of effect of these treatments’ physico-chemical characteristics, (TSS, pH, acidity and color), ascorbic acid, microbial stability and shelf life, of treated strawberry juices. After treatments and whether storage at room temperature at (22°C ±3) for 45 days or in refrigerator at (4°C ±1) for 105 days. Pulsed electric field device subject of study was effective as thermal pasteurization not only to achieve microbial stability juices, but also to obtain juices with a high content of vitamin C like fresh, perfectly.
