“…Shoot length, leaf area, fresh and dry weights of root and shoot were decreased by HT and drought while a remarkable reduction was observed in the combined treatments (Tables 2 and 3 ). These results were in line with those obtained by Bachiri et al and Suliman et al 24 , 26 . Drought stress reduces soil moisture, and HT increases water loss from cells, resulting in a decline of leaf RWC and turgidity 27 , 28 .…”

High temperatures (HT) and drought are two major factors restricting wheat growth in the early growth stages. This study investigated the role of glutathione (GSH) amendment (0.0, 0.5, 1.0, and 2.0 mM) to soil in mitigating the adverse effect of HT (33 °C, with 25 °C as a control), water regimes (60% of field capacity and control), and their combinations. HT decreased the length, project area, surface area, volume, and forks of the root, while drought had the reverse effect. Shoot length, leaf area, leaf relative water content, and shoot and root dry matter were significantly decreased by HT and drought, and their combined impact was more noticeable. GSH significantly promoted the root system, shoot growth, and leaf relative water content. The combined treatment reduced chlorophyll a, chlorophyll b, and total chlorophyll. However, 0.5 mM GSH raised chlorophyll a, chlorophyll b, and total chlorophyll by 28.6%, 41.4%, and 32.5%, respectively, relative to 0.0 mM GSH. At combined treatment, 0.5 mM GSH decreased malondialdehyde (MDA) by 29.5% and increased soluble protein content by 24.1%. GSH meaningfully enhanced the activity of superoxide dismutase, catalase, and ascorbate peroxide in different treatments. This study suggested that GSH could protect wheat seedlings from the adverse effects of HT and/or drought stresses.

“…The increase in seedling length and growth could be due to the improvement of SVI that occurred by 5-ALA (Table 6). Furthermore, application of 5-ALA to the soil significantly increased plant height, fresh and dry weight (Anwar et al, 2020;Suliman et al, 2021). The physiological mechanism behind 5-ALA in mitigation temperature and drought stress still need to be interpreted.…”

“…The combined effects of environmental stresses severely restricted most growth stages of plants (Hussain et al, 2019;Suliman et al, 2021). Germination is an essential developmental stage change in the life cycle of a plant, which plays an important role in crop establishment and environmental adaptation (Liu et al, 2019).…”

“…High temperature stress increased the occurrence of loss of seed quality associated with seed viability and germination (Wen, 2015). Moreover, the effects of increased temperature on wheat include growth retardation by reducing cell division and cell elongation resulting in dwarf plants as well as decreased root growth, number of roots and root diameter (Iqbal et al, 2019;Suliman et al, 2021).…”

Drought and temperature stresses are known as primary factors limiting germination and seedling growth. Seed priming with plant growth regulators is one of the popular approaches to minimize adverse environmental stresses. This study was carried out to examine the role of seed priming with 5-aminolevulinic acid (5-ALA) at different levels (0, 25, 50, and 100 mg L -1 ) in germination and seedling growth of three wheat (Triticum aestivum L.) 'Emam', 'Gomria', and 'Zakia' under high temperature and drought stresses using a range of temperatures (25, 30, and 35 ℃) and water potentials (0.0 and -0.5 MPa). Water uptake, germination and early seedling growth attributes were measured. Drought stress and high temperature decreased germination%, germination index, and shoot fresh weight by 39.2%, 35.4%, and 48.6%, respectively, as compared with 0.0 MPa and 25 ℃. Seeds of 'Zakia' primed with 50 mg L -1 5-ALA at -0.5 MPa, and 35 ℃ increased fresh and dry weights of the root by 19.8% and 68.4% relative to 0 mg L -1 . For interaction between variety and 5-ALA, the highest germination% (90.3%) was recorded in 'Emam' with 50 mg L -1 5-ALA. Treatment 100 mg L -1 5-ALA decreased mean germination time by 24.5% and 28.9% at 25 and 35 ℃, respectively; 50 mg L -1 5-ALA increased seedling vigor index by 16.3% as compared with 0.0 mg L -1 at -0.5 MPa and 35 ℃. The 5-ALA enhanced water imbibition of the three varieties under drought and temperature stresses. This study suggested that seed priming with 5-ALA is a possible way to mitigate the negative effects produced by drought and temperature stresses on germination and early seedling growth of wheat.

Melatonin (ML) is an indolamine that regulates a wide range of physiological processes as growth of roots and shoots, antioxidant enzyme activity, seed germination, photosynthetic efficiency promoting stress tolerance in plants, mitigating the harmful effects of abiotic stress. Effects of pretreatment of soybean (Glycine max (L.) Merr.) seeds with 10, 30, 60 and 90 μM ML were evaluated in seedlings under osmotic stress measuring germination speed index, and root protrusion, growth, and DM. Under osmotic stress, ML increased germination speed index at 10 (239%), 30 (194%) and 60 μM ML (189%); 5 th -day root protrusion by 290%, 214%, 185% and 85% (10, 30, 60, and 90 μM ML respectively). The application of 10 (328%), 30 (224%), 60 (265%), 90 μM ML (129%) increased root length, followed by root DM in stressed seedlings. Drought stress reduced photosynthetic efficiency, increased ROS, and reduced antioxidant enzymatic activities in soybean. In a second experiment, well-watered (100% field capacity) (WW) and drought stressed (DS) soybean plants received 30 and 50 μM ML. Melatonin increased rate of CO2 assimilation and net photosynthetic rate at 30 μM ML (WW) in 28% (2 d after application) and 50 μM ML (DS) in 48% (5 d after application). Melatonin increased antioxidant enzymes activity (catalase and peroxidase) in plants under drought stress. The ML application enhanced leaf area in WW plants, however decreased in stressed plants. An increased number of seeds, pod numbers, total seed mass, root DM were observed under WW. Drought stress increased numbers of seeds (27%), pod numbers (33%) and total seeds mass (27%) with 30 μM ML. These results demonstrated that ML mitigated negative effects produced by drought on germination and growth of soybean seedlings, and acted as a drought tolerance inducer, improving yield under stress condition.
