“…Date palm (Phoenix dactylifera L.) is important in reducing the damage of climate change because of its high ability to convert carbon dioxide into oxygen and carbohydrates (Shareef 2019). Date palm growth is impacted by environmental stresses, such as drought, salinity, and heat, which unfavorably influence the development and profitability of the plants (Jasim et al 2016).…”

The experiment was conducted in the Abi Al-Khaseeb orchard, Basrah, Iraq during the 2019 season, on date palm (Hillawi cv.). The effect of foliar nano-fertilizer on the response of the growth and fruit ripening rate was amid. Adding nano-fertilizer to the annual date palm fertilization program improved growth and increased production. A comparison of foliar NPK (1, 2 g L-1) as nano-fertilizer and traditional fertilizer, and combined, was applied. The results revealed that the treatment of foliar traditional and nano-fertilizers together increased the weight of fruit and bunches, water content, indoleacetic acid, and gibberellic acid relative to other treatments. Nano-fertilizers (1g L -1) led to an increase in fruit ripening rate, dry mass, and total soluble solids, activity of the enzymes peroxidase, and superoxide dismutase, and abscisic acid content. The leaflet protein expression shows that the appearance of protein bands 1 to 5 and 6 was up-regulated by control and traditional fertilizer. Whereas the protein bands 6 and 7 were down-controlled under nano-fertilizer. Hierarchical cluster analysis of proteins in the leaf in response to traditional and nano-fertilizer showed two distinct clusters. The use of nano-fertilizer individually leads to the acceleration of fruit ripening. while the production fruit that is increased using foliar nano-fertilizer with traditional fertilizer.

“…The increase in growth parameters when treated with potassium may be due to its positive role in improving the overall physiological activities within the plant cells, the most important of which is improving the effectiveness of photosynthesis and the composition of cell organelles (Aly et al, 2015), as well as improving hormonal balance by increasing growth-promoting hormones and reducing growth-inhibiting hormones (Hasanuzzaman et al, 2018). The reason for the increase in the leaf area can be attributed to the increase in the potassium concentration to the fact that the abundance of this nutrient for the plant in sufficient quantities is necessary for growth, specifically concerning its role in cell division, as well as improving the performance of plant hormones such as auxins and gibberellins, which directly enter into the expansion and elongation of cells, which increases leaf area (Shareef, 2019). This result agrees with Al-Furtuse et al ( 2019) obtained in cowpea plants (Vigna sinensis L.).…”

“…Potassium in homeostasis enhances enzyme synthesis, relieves oxidative stress, and improves signal transduction during stress (Souto et al, 2018). Furthermore, the plant can retain chlorophyll and sucrose translocation for a relatively long time in a sufficient potassium supply (Chrysargyris et al, 2017;Shareef, 2019).…”

Pre-treatment for heat tolerance enhancement of the Indian almond (Pithecellobium dulce) seedlings using ascorbic acid and potassium chloride

In light of global warming, pre-treatment plants with antioxidants may reduce the damage caused by climatic changes. Indian almond seedlings were planted in pots subjected to ascorbic acid and potassium chloride alone or combined to reduce the negative impact of high field temperature. Compared with the control, all treatments improved the plant height, branch number, number of leaves, and leaf area. These treatments reduced loss in concentration of photosynthetic pigments such as chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid. Heat stress increased abscisic acid content and electrolyte leakage percentage, whereas the application of ascorbic acid alleviated this damage. Indian almond plants can better withstand high temperatures particularly using ascorbic acid treatments at 50 mg l−1 or treatment of ascorbic acid at 50 mg l−1 + potassium chloride at 250 mg l−1 to reduce heat stress damage.

“…Drought and salinity are essential environmental issues prevailing in date palm (Phoenix dactylifera L.) cultivation regions where they can negatively impact growth and productivity (Al-Khayri & Al-Bahrany, 2004;Al-Bahrany & Al-Khayri, 2012;Shareef, 2019). Several types of genetic markers have been used to characterize date palm varieties under different stress conditions based on phenotypic (Elsafy et al, 2015), biochemical (Yaish et al, 2015)little is known about the underlying molecular mechanisms that contribute to its salt tolerance.…”

The formation of new proteins under the influence of harsh environmental conditions is a plant adaptation reaction. Two-year-old date palm tissue culture-derived plants from ‘Barhee’ grown in the field were subjected to salt stress (70 g l-1 NaCl) and dehydration-induced by applying 70 g l-1 polyethylene glycol or without irrigation and withholding irrigation (0 g l-1) for one month. The soluble carbohydrate content increased in response to salinity and polyethylene glycol treatment in leaves compared to the control and drought treatment without irrigation. Proline increased in all treatments. Malondialdehyde and hydrogen peroxide increased under salinity. Salinity treatment increased the activity of ascorbate peroxidase and catalase enzyme. Salinity and polyethylene glycol treatments increased abscisic acid, whereas the indoleacetic acid level decreased. The protein pattern of roots and leaves in one-dimensional polyacrylamide gel electrophoresis showed that the stress conditions led to new protein bands' appearance and other proteins' disappearance. A comparison of protein patterns between the control and stress treatments revealed that the relative intensity of proteins in roots and leaves were more associated with salinity treatment than the drought. The results may be clearing important the molecular mechanism of tolerance under the influence of extreme environmental stress.
