“…For instance, compared to the Castlerock and Fayrouz genotypes, the GS 12 hybrid showed higher biomass accumulation (plant height, number of leaves, and stem diameters). In this regard, various research studies showed variations in growth and development among different genotypes [50,51]. PGRs (BAP) probably enhanced the overall capability of the cells to produce essential organic compounds through biosynthesis [52,53].…”

Heat stress is one of the most critical environmental abiotic stresses that can negatively affect plant growth. This article investigates the role of a plant growth promoter (Benzylaminopurine) in tomato fields in regard to its ability to withstand high-temperature conditions resulting from greenhouse gas emissions and climate changes. Three genetically different tomato cultivars (Castlerock, GS 12-F1, and Fayrouz F1) were sprayed with 2% 6-Benzylaminopurine (BAP) at 300 and 600 ppm; then, growth and yield components, physio-biochemical characteristics, and antioxidant enzyme activities were determined. The results showed that the highest BAP concentration (600 ppm) enhanced the ability of tomato plants to withstand high temperatures and the maximum dose of BAP improved chlorophyll (71.7 spad units) in GS 12 leaves, while the same dose enhanced proline contents (24.91 mg/100g FW), total antioxidants (83.35 µmol Trolox/g dw), total phenolics (20.99 mg/g dw), Superoxide dismutase (33.74 U/g), peroxidase (46.30 U/g), and polyphenol oxidase (64.10 U/g) in Fayrouz F1 leaves. Application BAP on tomatoes moderately improved fruit quality, such as ascorbic acid and maturity degree, while BAP applications reduced TSS and acidity. In this investigation, taste index was not affected by Benzylaminopurine application but by tomato genotype. The highest number of fruits/plant (45.7), fruit yield/plant (3.98 kg), and total yield (103 tons/ha) were obtained from the GS 12 genotype.

“…For the chemical analysis of African millet, samples were taken during three phases: the phase of emergence into the tube, heading, and flowering. The plant dry matter was determined by drying to a constant weight at 100-105 • C [26]. The chemical analysis of the samples was conducted at 25 • C and at a relative humidity of 45%.…”

Introducing new forage crops such as Japanese millet (Echinochloa frumentacea) and pearl millet (Pennisetum glaucum) is crucial for mitigating the impacts of climate change in the dry steppe zone, expanding forage crop options, and obtaining nutritious feed for the development of animal husbandry. The aim of this study was to assess the productivity and feed value of these crops. Field experiments were conducted in 2021 and 2022 to investigate the changes and variations in the yields and chemical compositions of Japanese millet and pearl millet when grown as sole crops or in mixed cropping in the dry steppe zone of northern Kazakhstan. Among the annual crops sown via sole cropping, the hay of the Japanese millet, sown in the third decade of May and harvested during full heading, was observed to have a higher content of raw protein and other nutrients than Sudanese grass hay, that is, the raw protein content was higher at 1.81%, the raw oil content at 0.12, and the raw ash content at 1.88%. In addition, among the mixtures of crops, the hay of the crop mixtures containing pearl millet, sown in the above period and harvested as hay during the milky stage, the full heading stage, and the formation of spikelets in the grain family stage, differed from the hay of Sudanese grass sown in the same period and collected during full heading in terms of the contents of raw protein and other nutrients and the low content of raw ash, that is, the content of raw protein was at 2.16%, raw oil at 0.39, raw ash at 0.95, without nitrogen extractives (WNEs) at 3.78, and starch at 0.11. The calcium content was higher by 0.08% and carotene by 0.11 mg/kg, and raw lentils were lower by 0.94%. The analysis of the results revealed that the variation in the crops’ phenological phases depended on the moisture availability and the sowing time.

“…The following parameters were measured: leaf number per plant, leaf area, fresh weight (FW), and dry matter. The dry matter content was determined by drying the leaves at 50 • C till a constant mass was achieved [42]. Moisture contents (MCs) were calculated using the leaves' fresh weight and dry matter.…”

Studying the biostimulation effect of amino acids indicated their possible role in salt stress mitigation. In this investigation, six exogenous amino acids (alanine (Ala), arginine (Arg), glutamine (Glu), glycine (Gly), methionine (Met), and proline (Pro)) at 0.5 g/L were sprayed to evaluate their impact on lettuce plants cultivated under simulated salt stress conditions. Photosynthetic pigments, ion absorption, endogenous amino acids contents, catalase (CAT), and peroxidase (POD) enzyme activities were determined. A significant alleviation of salt stress was noticed when EAAs were used in the stress-induced plants, and applying Gly, Met, and Pro improved the plant status under salt stress conditions. The highest electric conductivity (568 μS/g) was testified from the control treatment (50 mM NaCl), while applying exogenous amino acids reduced electrical conductivity (EC), and the result was located between 469 and 558 μS/g. AAs alleviated Cl- anions in the lettuce leaves by 25% in comparison to control plants. Na+ cations were alleviated when the stress-induced plants were sprayed with amino acids. In contrast, applying amino acids promoted K+ uptake, and Arg presented the highest contents (3226 μg/g). AAs promoted chlorophyll (chl a and chl b) concentrations compared to the control treatment, and Met produced the maximum chl a content, while the carotene (car) contents significantly augmented when Gly, Met, and Pro were applied. AAs were highly generated in non-stressed treatment (Std) compared to the control. Under simulated salinity stress, Met and Pro application enhanced proteinogenic amino acids expression. Compared to Ctl treatment, peroxidase enzyme activities significantly diminished in the other treatments, which fell by over 40% when Gly, Met, and Pro were sprayed.
