  • Productivity of wormwood (Artemisia abrotanum) enhanced by trace elements

    • Authors: Khalid, Khalid A.;  Advisor: -;  Participants: El-Gohary, Ahmed E. (2020)

  • Obtained results showed that Fe (3 g/L), Mg (8 g/L), or Mn (300 mg/L) resulted in the greatest values of growth characters (plant height, fresh and dry weights of aerial parts), EO content (% and mL/100 plants), major constituents of EO (2-hydroxy-1, 8-cineole, β-eudesmol, and camphor), nutrient contents, and their uptakes. Different changes were found in various chemical classes of EO (mono and sesquiterpenes).

  • Impact of gasoline fuel emissions on Rhizopus stolonifer (Ehrenb.) Vuill. and Fusarium oxysporum (Schlecht.)

    • Authors: Balogun, Kayode Peter;  Advisor: -;  Participants: Aborisade, Abiola Titilola; Oladele, Oluwole Olakunle (2020)

  • Alteration in the normal composition of gasses in the atmosphere referred to as air pollution can occur as a result of different processes, including emissions from vehicles and power generators. Gasses affect living things directly and indirectly by playing roles in respiration, membrane function, synthesis, and growth. The gasses contained in fumes emitted from vehicles and generators may likely have effect on microorganisms in the environment including microfungi. Two microfungi were selected to study the effect of generator emissions on their growth.

  • Physiological and biochemical responses of soybean (Glycine max L.) to cysteine application under sea salt stress

    • Authors: Sadak, Mervat Sh.;  Advisor: -;  Participants: Abd El-Hameid, Asmaa R.; Zaki, Faten S. A.; Dawood, Mona G.; El-Awadi, Mohamed E. (2020)

  • Cysteine treatments could alleviate the adverse effect of salinity stress on growth and yield of soybean plant through increasing photosynthetic pigments; proline content; N, P, and K contents; superoxide dismutase and catalase activities; and oil% accompanied by decreases in H2O2 and MDA contents as compared with their corresponding controls. In addition, cysteine treatments and/or salinity stress exhibited differences in protein pattern from 112 to 19 kD molecular weight. The appearance of new protein bands reflected the expression of cysteine treatments and salinity stress.

  • Impact of soil application with humic acid and foliar spray of milagro bio-stimulant on vegetative growth and mineral nutrient uptake of Nonpareil almond young trees under Nubaria conditions

    • Authors: Abourayya, Mahmoud Sami;  Advisor: -;  Participants: Kaseem, Nabila Elbadawy; Mahmoud, Thanaa Shaban Mohamed; Rakha, Amal Masoad; Eisa, Ramadan Ahmed; Amin, Osama Abdelfattah (2020)

  • The results showed that different treatments improved the vegetative growth of seedlings, stem length, diameter, number of branches and leaves, leaf area, leaf fresh and dry weight, and specific leaf dry weight as well as leaf chlorophylls and minerals content comparing with untreated young trees. Soil application of 30 g humic acid along with 30 ml/l milagro per young tree as foliar spray was the promising treatment as a new fertilization technique that is non-chemical, low-cost, and environmentally safe for improving growth and nutritional status of Nonpareil almond young trees under Nubaria conditions.

  • The physiological effect of pre-soaking with tryptophan on sugar beet (Beta vulgaris L.) productivity under different levels of salinity stresses

    • Authors: Hozayn, M.;  Advisor: -;  Participants: Abd-Elmonem, A. A.; Samaha, Ghada M. (2020)

  • The results revealed that the pre-soaking in tryptophan treatments (2.5 mM) were the most effective treatments under different salinity levels and caused significant increases in all tested parameters of this study. Moreover, increasing salinity levels decreased significantly the root purity parameters and increased impurity parameters of sugar beet. The DS-9004 cultivar gave the highest values of all studied parameters compared with the LP-15 cultivar under different salinity levels with tryptophan (2.5 mM). Chlorophyll a content and chlorophyll a/b ratio, as well as carotenoids content, were highest in DS-9004 cultivar, while chlorophyll b content was highest in LP-15 cultivar at 75 days.

  • Mitigation the adverse effect of salinity stress on the performance of the tomato crop by exogenous application of chitosan

    • Authors: Ullah, Naeem;  Advisor: -;  Participants: Basit, Abdul; Ahmad, Imran; Ullah, Izhar; Shah, Syed Tanveer; Mohamed, Heba I.; Javed, Shahryar (2020)

  • The data revealed that various application of salinity had a negative effect on almost all the studied parameters. Tomato plants treated with distilled water having no salinity (control) recorded maximum plant height (cm), average number of compound leaves plant−1, leaf area (cm2), stem diameter (mm), number of fruits plant−1, fruit firmness (kg cm−2), leaf chlorophyll content (SPAD), fruit juice pH, yield plant−1 (kg) and minimum total soluble solids (Brix°). Whereas, minimum plant height (cm), average number of compound leaves plant−1, leaf area (cm2), stem diameter (mm), number of fruits plant−1, fruit firmness (kg cm−2), leaf chlorophyll content (SPAD), fruit juice pH, yield plant−1 (kg) and maximum total soluble solids (Brix°) were found in plants treated with salinity level of...

  • Growth and chemical profile of clary sage (Salvia sclarea L.) in response to algae and banana peel extracts

    • Authors: El-Gohary, Ahmed E.;  Advisor: -;  Participants: Amer, Heba M.; Salama, Adel B.; Wahba, Hend E.; Khalid, Khalid A. (2020)

  • The highest values of fresh and dry weights were detected with the treatment of 1.5 g/l (BPW) × 1.5 g/l (ALS). The maximum inhibition of free radical -cavenging activity was recorded at 1 g/l (ALS) × 0.5 g/l (BPW). 2 g/l (ALS) without BPW treatment resulted in the greatest amounts of total carbohydrates. The greatest accumulation of total flavonoids was obtained from the plants treated with 0.5 g/l (BPW) × 1 g/l (ALS). Plants exposed to 1.5 g/l (BPW) with 2 g/l (ALS) gave the greatest accumulation of total phenols. Phenolic compounds that were detected by HPLC analysis were changed due to ALS, BPW, and their interactions.

  • Physiological and biochemical role of proline, trehalose, and compost on enhancing salinity tolerance of quinoa plant

    • Authors: Ahmed, Sium;  Advisor: -;  Participants: Moni, Bilkis Mehrin; Ahmed, Shawon; Gomes, Donald James; Shohael, Abdullah Mohammad (2020)

  • Growth and yield measurements were decreased with salinity stress. High levels of both proline and trehalose recorded the highest values of total soluble sugars, proline, and free amino acids in both unstressed or salinity stressed plants with or without compost addition. The use of compost in soil for cultivating quinoa plants with either proline or trehalose treatments increased growth parameters, photosynthetic pigments, and yield attributes. In addition, these treatments improved the accumulation of some organic solutes in leaves and promoted antioxidant enzyme activities.
