“…Regarding the interaction effect of AsA and CB factors under our study effect on yield and yield quality, the obtained data showed that the highest values of all parameters were recorded with foliar spray of AsA at the 1 Mm concentration and inculcation seeds with blue-green algae in both seasons. Similar results were obtained by [50,51]. In addition, AsA plays an important role in preserving the activity of enzymes.…”

A field experiments were conducted during the two summer seasons of 2015 and 2016 in saline soil (ECe = 9.0 dSm-1), at Fayoum province, Egypt to study the effect of ascorbic (AsA), as foliar application alone or combined with cyanobacteria (CB) on growth, yield, its components and nutritional status of sunflower plants variety Sakha 54. Treatments comprised 2 ascorbic acid (AsA) levels with or without seed inoculation with cyanobacteria (CB). They were 1 mM AsA, 2 mM AsA, 1 mM AsA + CB and 2 mM AsA + CB in addition to the control treatment in which seeds were not received CB and their plants were sprayed with distilled water. Results could be summarized as follows: increasing the addition of ascorbic acid concentration up to 1Mm with combination of CB increased significantly values of growth attributes (e.i., plant height, of leaves no. /plant, shoot dry weight and leaf area), photosynthetic pigments (chlorophyll a, b and carotenoids), physiological responses (total soluble sugars, proline and soluble phenols) as well as the head diameter, seed yield/ plant, 100 seed weight and seed yield (t ha-1). Also, N, P, K, Fe, Mn, Zn and oil percentage of sunflower seeds with compared to control treatment in both years. Generally, the results in most cases, demonstrate that the all parameters increased significantly by using the concentration of ascorbic acid 1Mm combined with CB in both seasons

“…Seed priming with appropriate plant growth regulators can increase metabolic and enzymes activities, which can facilitate the preparation of seeds for rapid germination 33 . Similar nding was also remarked in Sun ower (Helianthus annuus L.) by 39 ,who observed that, improved in emergence percentage and rate in seeds soaked with ASA may be due to improved oxygen absorption, increased α-amylase activity, and increased transfer of nutrients from cotyledons to embryos.…”

Salt stress is one of the major environmental stresses that limits the growth, antioxidant defense and sustainable crop productivity. A controlled study was done to determine the ameliorative effects of ascorbic acid (ASA) (0, 568, and 850 μM) and biochar (BC) (0, 2 and 4% BC [w/w]) on emergence, growth, and physiological attributes of sorghum grown under three salinity levels (0, 100, and 200 mM NaCl). High salinity stress significantly reduced emergence percentage, emergence rate, shoot length, root length, specific root length, total fresh weight (T.F.W), total dry weight (T.D.W), the activities of peroxidase (POD), superoxide dismutase (SOD), and catalase (CAT), but increased malondialdehyde (MDA) content. At the 200 mM NaCl level, 850 μM ASA with 4% BC enhanced most of the physiological attributes determined. At the 200 mM salinity level, total dry weight of sorghum seedling was increased by 42.7% and 23.1% at 2% and 4% BC levels, respectively as compared with non-BC control. The highest emergence rate at 200 mM NaCl was achieved at 4% BC and 850 μM ASA level. Our study suggested that the combined application of ASA and BC at appropriate amount and concentration on sorghum seedling may be helpful in salt tolerance and getting increase antioxidant enzymes that mitigate harms affected by saline problems worldwide.

“…Then there is a second phase of growth reduction, which is due to salts accumulation in transpiring leaves to excessive levels, exceeding the ability of the cells to compartmentalize salts in the vacuole. The consequences of Na + or Clbuild-up in the cell walls are often catastrophic and include dehydration and oxidative stress (Munns, 2002;Fatemi, 2014), finally causing leaf dieback. If the rate of leaf dieback will be faster than the rate of leaf expansion, the consequence will be the decrease of root dry matter and gradually deteriorated status of plant's water and nutrient supply.…”

The study aimed to investigate the effects of commercially available AMF inoculate (Glomus sp. mixture) on the growth and the nutrient acquisition of garden pea (Pisum sativum L.) plants. Inoculated (AMF+) and non-inoculated (AMF-) pea plants were subjected to two levels of NaCl salinity (0 and 50 mM NaCl). Several times during the growing cycle, randomly selected plants were analyzed for dry matter of roots and the aboveground biomass. Plant tissue samples were analyzed for N, P and K concentration and the total uptake, specific absorption rate (SAR) and specific utilization rate (SUR) of these elements were calculated. Raised salinity drastically decreased the dry matter of roots and aboveground biomass and significantly deteriorated the specific utilization rate (SUR) of main nutrient elements in pea plants. The presence of AM fungi significantly reduced the dry matter of roots, but on the contrary significantly increased the dry matter of shoots and the overall plant dry matter. Furthermore, AM fungi inoculation significantly increased the specific absorption rate (SAR) of N, P and K under both; control and saline conditions and enhanced the specific absorption rate (SUR). As a conclusion, the inoculation of garden pea with AM fungi significantly increased the volume and improved biomass production in pea grown as greenhouses soil amendment crop (green manure).
