“…Generally, application of HA was superior in its effect than CHT one, especially at highest concentration (2000 ppm) since giving the highest values for tested traits in both seasons. These results in accordance with findings of earlier studies which reported that application of CHT caused increase in total chlorophylls (Dzung et al, 2011;Salachna et al, 2015;Byczyńska, 2018;El-Khateeb et al, 2018 ), carbohydrates content (Bistgani et al, 2017;Shafiei-Masouleh, 2019) and K, Ca% (Dzung et al, 2011). Whereas, the marked increase in tested components due to HA treatments are in conformity with prior studies that reported stimulatory influence of HA in augmentation of chlorophylls and carbohydrates content (Farahat et al, 2012;El Sayed et al, 2016;Abou Dahab et al, 2017;Noor El-Deen and El-Ashwah, 2019), increase K% (Zhang et al, 2014;Ibrahim et al, 2016;Noroozisharaf and Kaviani, 2018) and Ca% (Nikbakht et al, 2008;Dorria et al, 2018).…”

Pots experiment was conducted to investigate the effect of bio-stimulators chitosan (CHT) or humic acid (HA) on Vitex trifolia ‘Purpurea’ exposed to salinity stress. Salinity stress was imposed by irrigation with saline water at concentration of 1000, 2500 and 5000 ppm, in addition to control (280 ppm), plants exposed to salinity were sprayed every 4 weeks with either CHT at concentrations of 30, 60 and 90 ppm or HA at concentrations of 1000, 1500 and 2000 ppm, while control plants sprayed only with tap water. The results showed that, with increasing salinity stress all vegetative growth parameters were decreased and chemical constituents including total chlorophylls total carbohydrates, K+ %, Ca2+ % and K+/Na+ ratio were reduced. In contrast, elevating salinity stress increased contents of proline, total phenolic, Na+ %, Cl− %. On the other hand, foliar application of either CHT or HA had favorable impact on increasing vegetative traits and chemical compositions, meanwhile reducing accumulation of total phenolic, Na+ and Cl− % toxic ions in leaves, HA was generally more effective than CHT. Based on the results, it can be recommended that, CHT or HA at high concentration was the best effective treatments; however, HA was superior and economic treatment recommended for alleviating the adverse impact of salinity stress on Vitex trifolia ‘Purpurea’ plants irrigated with saline water at concentration up to 5000 ppm.

“…The low est value (15.99 %) was obtained from plants irrigat ed with the longest intervals (12 days) and not received any biostimulators treatments, whereas the highest mean value (38.64%) was resulted from plants irrigated with the shortest intervals (3 days) and sprayed with BRs at 200 ppm. The results of increasing total carbohydrates due to CHT treatments are the same as the results of previous researches (Zohreh et al, 2017;ShafieiMasouleh, 2019;Elansary et al, 2020;Ashour et al, 2021;Salachna and Pietrak, 2021). While, the beneficial increase in total carbohydrates due to BRs treatments are in agreement with earlier studies (Mohamed, 2020;Pacholczak et al, 2021).…”

“…Chitosan (CHT) is a deacetylated derivative of chitin. It is a natural polymer and biodegraded by bio logical agents and it is environmentfriendly used in agriculture (ShafieiMasouleh, 2019). Under stressed conditions, CHT has the efficiency to mitigate the harmful effects of drought by promoting chlorophyll, carbohydrates, proline content and the capacity of antioxidant activities (Pirbalouti et al, 2017;Vosoughi, et al, 2018;Elansary et al, 2020).…”

Pot experiment was conducted to evaluate the effect of chitosan or brassinolide applications on morphology and physiology parameters of Azadirachta indica grown under water deficient stress. The plants received different irrigation intervals, and were sprayed monthly with either chitosan or barrasenolide each at concentrations of 50, 100 and 200 ppm, while the control plants were sprayed only with tap water. The results showed that water stress reduced all growth parameters, chemical constituents of pigments content, total carbohydrates, N, P and K %, total indoles, while proline and total phenols content were increased. Instead, the plants sprayed with the higher concentrations of chitosan or brassinolide resulted in significant increase in growth parameters, pigments content, total carbohydrates, proline content, N, P and K %, total indoles while reduced total phenols content. Based on the obtained results it can be concluded that, foliar application of chitosan or brassinolide at 200 ppm can alleviate the adverse effects of water deficient stress on the growth and physiology parameters of Azadirachta indica.

“…Furthermore, iron as the determinant element plays a role in other key biochemical processes, including respiration, symbiotic nitrogen fixation, electron transport system, biosynthesis of chlorophyll and cytochrome, nutrient uptake, and DNA and protein synthesis as well as photosynthesis as an activator. Alkaline soils may cause iron deficiency in many plant species (Nemati Lafmejani et al 2018 ; Hatamzadeh and Shafiei-Masouleh 2019a souleh 2019 ; Shafiei-Masouleh 2019 ; Haydar et al 2022 ). Iron is a low-mobile and more important micronutrient than other micronutrients for plants.…”

Goldenrod ( Solidago virgaurea L.) is considered for their medicinal properties for humans. These properties are attributed to some volatile compounds that can be extracted from above- and underground organs of plants. More ingredients of medicinal plants are undoubtedly considered by herbal medicine activists. The study aimed to promote Solidago yield and quality under foliar application of Fe 2 O 3 nanoparticles that can be considered as a safe and healthy fertilizer on the basis of US Food and Drug Administration (FDA) regulatory process about color additives. The experiment was performed with concentrations of Fe 2 O 3 nanoparticles (0, 0.5, or 1 mg L −1 ) and foliar application times (1, 2, 3, 4, or 5 times) on 4- to 5-leaf plants of Solidago virgaurea . Results showed that 4 times foliar application of 1 mg L −1 caused the best plant growth and mineral element contents (nitrogen, phosphorous, potassium, copper, and zinc) except for Fe content that the more the times of foliar application, the more the Fe content increased. However, the flavonoid (rutin and quercetin) and essential oils (caryophyllene, alpha-pinene, camphene, limonene, linalool, myrcene, and terpinene) as biochemical and medicinal qualities of the treated plants were remarkably promoted when 1 mg L −1 of nanoparticles was sprayed 5 times. Furthermore, the more the element contents, the more the ingredients. Finally, based on the goals of herbal medicine activists for the production of the essence, extract, or herb, both 5 and 4 times of foliar applications of ferric oxide nanoparticles are safe and may be economic and recommendable.
