“…The study aimed to evaluate the role of growth stimulants viz., salicylic acid, hydrogen peroxide (H 2 O 2 ), calcium chloride (CaCl 2 ), and succinic acid in accelerating seed germination and improving the morphological, physiological, and biochemical characteristics of amaranth seedlings at low positive temperature. Seed treatment with growth stimulants significantly reduces the negative effects of cold by regulating the antioxidant potential and mechanism through increase amaranth synthesis of ascorbic acid and the total content of water-and alcohol-soluble compounds (Platonova et al, 2018). Numerous studies have shown that, as a result of seed treatment with growth stimulants, the values of the seed germination parameters, i.e., germination index, viability index, seed vigor index, as well as, the shoot length of the hypocotyl, root length, seedling fresh weight, and seedling dry weight were enhanced in various crop plants (Gaba et al, 2018;Cao et al, 2020;Mewar et al, 2020;Ahmad et al, 2020;Vdovenko et al, 2021).…”

The recent research evaluated the effects of growth stimulant seed treatment on the morphological traits of Amaranthus hypochondriacus L. cv. ‘Krepysh’ grown under optimal and low positive temperature conditions. The seeds were continuously soaked for 4 h in five different solutions of growth stimulants, i.e., salicylic acid (SAA - 138 mg/L), hydrogen peroxide (H2O2 - 10 and 50 mmol/L), calcium chloride (CaCl2 - 3000 mg/L), succinic acid (SUA - 500 mg/L), and control (distilled water). The stimulant-primed seeds were germinated at optimal temperature (23°C) and continued to germinate at low temperatures of 10°C (T10) and 23°C (T23). The results showed that seed germination rates viz., germination potential (GP), germination rate (GR), germination index (GI), viability index (VI), and seed vigor index (SVI), were significantly improved with seed quality potential compared with the control. Under low positive temperature, seeds treated with succinic acid, H2O2, and CaCl2 had the most significant effects on improving seed quality and induced cold resistance in the seeds. The morphological indicators of amaranth seedlings, i.e., biomass, hypocotyl, and root length, were also significantly improved with seed treatment by growth stimulants. Priming of amaranth seeds with hydrogen peroxide and succinic acid showed a greater increase in seedlings’ biomass at room (23°C) and low (10°C) temperatures. The seed treatment with SUA and SAA significantly contributed to enhancing the hypocotyl length. The amaranth roots achieved maximum length after seed treatment with SUA and CaCl2. In general, the seed treatment effects on seedling's biomass under chilling stress were associated with the potential of inducing cold tolerance in seedlings.
