The present study was conducted during the two seasons 2021 and 2022 on eight-years-old of LeConte pear cultivar for enhancing fruit set, yield and quality by preharvest foliar spray of some plant growth regulators. Preharvest treatments included: control (spray with water only), nitrophenolate sodium (NPS) at 200 ppm, GA 4+7 at 10ppm, thidiazuron (TDZ) at 5ppm, NPS plus GA 4+7 , NPS plus TDZ and NPS plus GA 4+7 and TDZ. All preharvest foliar treatments were sprayed at full bloom and after fruit set with ten days. The results showed that treatment with 200 ppm of nitrophenolate sodium increased fruit set, fruit firmness, TSS and carotenes. Increases in shoot length, fruit pedicel length and diameter, fruit set, yield, and acidity were seen after treatment with GA 4+7 at 10 ppm. Carotenes and TSS in fruit were decreased. On the other hand, thidiazuron treatment at 5ppm increased pedicel fruit diameter, fruit set, yield, firmness, fruit diameter and acidity. Fruit TSS and carotenes were decreased.

Selenium is one of the most important trace elements in animal nutrition, as it helps animals stay healthy and productive. Selenium is a vital component of poultry nutrition, and its bioefficacy is determined by the chemical form in which it is consumed. Inorganic Se, such as sodium selenite, and organic Se, such as Se-enriched yeast, DL-selenomethionine, and nano-selenium are available as Se supplements in the poultry diet. Because chickens are unable to synthesize Se, dietary supplementation is an important technique for combating commercially significant stressors. Indeed, in stressful situations, when increased selenoprotein expression necessitates additional Se, and Se provision via feed is typically reduced due to reduced feed consumption, Se reserves primarily in the muscles could help maintain an effective antioxidant and prevent stress-related harm. For commercial application, the poultry industry is looking for the most effective sources of environmentally friendly Se. The benefits and drawbacks of Se sources for poultry (inorganic, organic, and nanoparticles) are discussed in this review, as well as future directions for the development of new Se sources and the recommended levels as well as mode of actions.

Using medicinal extracts is one of the most important alternative methods for producing nanoparticles, due to it is safe, biocompatible and eco-friendly. Hyoscyamus muticus leaf extract was used in this study for the green synthesis of Magnesium Oxide nanoparticles (MgO NPs) by mixing it with a solution of magnesium nitrate. Several techniques were done to characterize the obtained material, including Scanning Electron Microscopy (SEM), Ultraviolet-Visible (UV-Vis) Spectroscopy, X-ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR). Aspergillus ochraceous (A. ochraceous) and Aspergillus niger ( A. niger) were incubated at different temperatures. The results indicated that 27°C and 35°C were the optimum temperatures for the growth, respectively. The effect of MgO NPs on the growth and metabolism (α-amylase) of A. niger and A. ochraceous were studied under optimum temperatures. It was observed by adding MgO NPs at concentrations of 0.25%, 0.5% and 1%; fungal growth was inhibited with 11%, 19% and 89% for A. niger and 67%, 76% and 100% for A. ochraceous . The metabolism of Aspergillus species as α-amylase completely prevented at all concentrations of MgO NPs. The purpose of this research is to compare the effects of climate change factor and MgO NPs on the growth of A. niger and A. ochraceous and α-amylase production.
