“…The non-toxicity of PEG 6000 in relation to living objects and its lack of participation make it promising for use in laboratory evaluation of the tree crops' sustainability. PEG 6000 reduces the water potential of the nutrient medium but does not penetrate the cell itself (Kovalikova et al, 2020, Mohanlal et al, 2021. The PEG effect includes the structural and functional restructuring of the photosynthetic apparatus and inhibition of photosynthesis.…”

Background: Droughts during the growing season are becoming increasingly common due to climate change and global warming. The study’s goal study was to assess the adaptation mechanisms of C. coggygria Scop. under simulated water deficit conditions using indicators characterized changes in the leaf stomatal apparatus and photosynthesizing system. Methods: The influence of osmotic polyethylene glycol 6000 on the research object C. coggygria regenerants was studied in vitro. Such indicators as morphological changes, pigment content, stomatal density and size and stomatal slit size were quantified. Result: Due to the influence of osmotic stress, there was a pigment content increase in the leaf plate on osmotic media. Stomatal density raised by 27.0-29.8% in explant cells cultivated on PEG 4.0-6.0%. Under the osmotic influence, there was a drop in the stomatal cells’ area and shape and the ratio of stomatal length to width in the regenerant leaves decreased from 1.5 to 1.0-1.1. These results indicate the adaptation of C. coggygria regenerants to stress caused by an artificial drought in vitro. The changes’ identification in the stomatal apparatus and the C. coggygria pigment ratio will accelerate the selective screening of drought-resistant plants for use in protective forestry.Background: Droughts during the growing season are becoming increasingly common due to climate change and global warming.

Background: Nickel can act as micronutrient essential for nitrogen fixation in legume crops or it can cause toxicity when present in high concentration. Rhizospheric supplement of Nickel be at a dose not beyond its beneficial level. Methods: An experiment was conducted for mash bean genotypes to evaluate the toxic level of Nickel concentrations. Seeds of four genotypes were sown in earthen pots filled with homogenized loamy soil. Nickel was added as its chloride salt solutions at the age of twenty days @ 15.0, 30.0, 45.0, 60.0, 75.0 and 90.0 mg kg-1 soil. Yield plant-1 and its contributing factors were recorded at physiological maturity of crop. Result: At low concentration, Nickel appeared to be non toxic and high doses reduced yield attributes. The lowest significantly effective dose which affected the parameters was 45 mg kg-1 except for number of legumes plant-1 for which same was true at 60 mg kg-1. While, the most effective dose was 45 mg kg-1 for each attributes. The observations were excluded from the ongoing trend when 15 mg kg-1 Nickel reflected positive role. Of the genotypes, MASH 80 was the least productive while MASH 88 was the most productive. In terms of grain numbers, MASH 97 was the least sensitive.
