“…It decreases in the content of all pigments (chla and chlb, total chlorophyll, and carotenoids). this finding took the same trend found by [73][74], and , as stated in the results on parsley of [75] and [76] on the fennel plant. While the fenugreek plant showed more resistance to increasing the concentration of NaCl in the irrigation water, the effect of increasing the salt concentration was not significant except with Chl b and carotenoids, in contradiction with the result of [26] regarding the content of carotenoids.…”

Aims: To discover the resistance of the Yemeni genotype of fenugreek to salt stress and the impact of salicylic acid on alleviating salt stress. Study Design: The experimental design adopted a completely randomized block design (RCBD), with pots filled with a 1:2 mixture of sand and soil serving as the experimental units. Place and Duration of Study: in a mini greenhouse covered with white polyethylene plastic sheet at Taiz University during the spring season 2021. The average temperature ranged from 32 ℃ during the day to 29 ℃ at night. chemical analyses were performed at the pharmaceutical laboratory in Al-Saeed University. Methodology: The fenugreek genotype was subjected to varying salinity levels (0, 50, 100, 150, and 200 mM) and the impact of salicylic acid (at concentrations of 0, 0.1, and 0.5 mg/l) in alleviating salt stress effects was examined at two time points: 15 and 30 days after 2 weeks of germination. Results: Increasing salinity significantly reduced shoot and root length and exhibited slight fluctuations influenced by salinity levels above 100 mM. Salicylic acid (SA) significantly reduced shoot length but had no effect on root length. Salinity had no appreciable effect on shoot dry matter (SDM%), while the application of SA significantly decreased it. Root dry matter percentage (RDM%) showed a notable and sharp increase with salinity. However, no appreciable changes in RDM% were observed in response to the SA application. In response to salinity, the ratio of SDM% to RDM% in treated plants decreased sharply, with the lowest ratio achieved when 0.1 SA was used for treatment. There were no significant modifications observed in the amounts of photosynthetic pigments in fenugreek leaves, including chl a, chl b and total chl. Nevertheless, using high concentration of Nacl led to a signifcantly reduced in the carotenoids and the chl. b. The protein content of fenugreek plants treated with salt was much higher than that of control plants. Also, protein levels increased with SA treatment across all NaCl concentration. Proline levels sharply increased with rising salinity, reaching a peak in approximately 22.28 ug/g DW. Application of 0.1 SA led to the highest proline level in comparison to other treatments, which was the highest level of Nacl in the second measurement time. Proline levels in plants treated with 200 Nacl and 0.1 SA were the highest, averaging roughly recorded 49.95 ug/g DW. APX significantly affected on fenugreek plants, the highest APX content was found in plants treated with 50 mM NaCl, the application of 0.1 SA produced the highest level of APX (0.373nm/g protein/minuet) in fenugreek. Catalase (CA) levels significantly decreased, but SA application did not affect CA levels. The data obtained may help in determining fenugreek cultivation areas and in managing breeding programs.

“…Further confirmation of this capability was provided by the significantly negative correlation between the antioxidant enzyme activity in pollen and the pollen activity as well as that between the antioxidant enzyme activity and the germination rate. Typically, the part of a plant that is most severely damaged by exposure to high temperature stress is the cell membrane, and because MDA is one of the key products of membrane lipid peroxidation, the level of MDA elevation in the cell membrane is a good indicator for the level of heat‐stress‐induced damage incurred by a plant (Desire & Arslan, 2021; Sun et al., 2021). The results of our experiment indicated that the MDA content of pollen from plants subjected to high temperature stress was significantly higher than that of pollen from plants from the control groups, where it should be noted that the MDA elevations we measured in pollen from XY335 plants subjected to heat stress were significantly greater than those we measured in the pollen from ZD958 plants, indicating that the former had incurred more cell membrane damage from exposure to heat stress than the latter.…”

In recent years, the frequency and intensity of exposure to heat stress have increased gradually, seriously hampering the production of maize. This paper presents a study designed to analyze how the development, physiology and dispersal of pollen from the heat‐resistant maize variety Zhengdan958 and the heat‐sensitive maize variety Xianyu335 are affected by exposure to heat stress during the tasselling stage. Our results showed That exposure to heat stress significantly increased the antioxidant enzyme activity in pollen. Upon visual inspection of the pollen, we found that the lower water content had given rise to wrinkles in the pollen surface, sunken germination pores, and morphological deformations. In addition, the anther dehiscence process was hindered, resulting in a reduced amount of pollen being dispersed. We also found elevated levels of abscisic acid (ABA), jasmonic acid (JA) and its derivatives, indole acetic acid (IAA) and gibberellin‐3 (GA3) in heat‐pollens, as well as elevated ratios of IAA to ABA and ABA to GA3. Ultimately impaired pollen fertility. Summarizing, our experiment revealed that reduced pollen quantity and quality are significant contributors to fertility losses in summer maize exposed to heat stress at anthesis, and we hope that our analysis of the physiological mechanisms involved can contribute to the development of crop management measures aimed at countering the increasingly detrimental effects of heat stress on the production of summer maize.

“…AMF plays an important role in stimulating plant uptake of water and nutrients such as phosphorus and increasing the plant root surface area (Ren et al, 2019), increasing plant tolerance to adverse conditions especially salt stress (Bijalwan et al, 2021) via improving chlorophyll content, photosynthetic efficiency and capacity, hormone homeostasis and antioxidant activity (Youssef et al 2018, Bijalwan et al 2021and Wu et al, 2021 and thereby enhancing the plant growth, survival rate, yield, and fruit quality under biotic and abiotic stressful conditions. Salicylic acid, a monohydroxy-benzoic acid, is one of the strong candidates for salinity ameliorators (Khan et al 2014, Youssef et al 2018, Naeem et al 2020and Desire & Arslan 2021 that have recently been recognized as a naturally occurring plant hormone that can be involved in diverse plant physiological and biochemical processes including plant growth, flower induction, photosynthesis, thermogenesis, nutrient uptake, membrane permeability, ethylene biosynthesis, stomatal movements and enzyme activity (Hayat et al, 2010, andRam et al, 2014). Youssef et al (2018) found that salicylic acid attenuated the adverse effects of salinity on growth and yield and enhanced peroxidase isozyme expression more competently than the other osmoprotectants, proline and glycine betaine, in cucumber plants.…”

S ALINITY is one of the serious abiotic stresses adversely affecting the productivity of most crops. Arbuscular mycorrhizal fungi and salicylic acid treatments are known to ameliorate salinity stress, but their combined effect has never been examined on watermelon. Therefore, to investigate the synergetic effects of them on vegetative growth, nutrient content, physiological and biochemical characteristics, and fruit yield and quality of watermelon cv. Aswan F1 grown under saline water conditions, a split split-plot design with three replications was conducted in the North Sinai Governorate, Egypt, during the two successive growing seasons of 2020 and 2021. The main factor included irrigation water salinity regimes at three levels: 1600, 4000 and 5000 ppm. Subfactors included arbuscular mycorrhizal fungi at two levels (noninoculated and inoculated), and salicylic acid foliar spraying at four concentrations (0, 1, 2 and 4 mM) in subplots. The results revealed that saline water increasing led to evident reductions in vegetative growth parameters and fruit yield. Mycorrhizal inoculation or foliar application of salicylic acid improved the growth and productivity of watermelon plants under salinity conditions by maintaining a higher leaf relative water content and membrane stability index, enhancing chlorophyll content, and inducing the accumulation of proline and the activity of antioxidant enzymes. In addition, this study affirmed the synergistic effects of mycorrhizal inoculation and salicylic acid spraying on ameliorating the deleterious effects of saline-water irrigation on the growth and productivity of watermelon plants via generating simulative impacts on all physiological and biochemical attributes.
