“…After filtration, the hormone components were dried with nitrogen and dissolved in phosphate buffered saline (PBS, pH 7.5) containing 0.1% (v/v) Tween 20 and 0.1% (w/v) gelatin, and then analyzed by ELISA. IAA, Z, ZR, and ABA hormone determination kits were provided by the crop chemical regulation research center of China Agricultural University [82].…”

Salt stress inhibited the growth of maize. B46 and NC236 were chosen as materials and NaCl concentrations (0, 55, 110, 165, and 220 mmol L−1) were set. We found the activities of SOD, POD, CAT, APX, GR, MDHAR, and DHAR decreased under NaCl stress. Compared with NC236, the contents of AsA and GSH, AsA/DHA and GSH/GSSG of B46 decreased. The content of O2−, H2O2, MDA, and EL of B46 increased. The contents of NO3− and NO2− decreased, while the content of NH4+ increased under high NaCl concentration. The activities of NR and NiR decreased, while the activities of GS and GOGAT increased first and then decreased. For B46 and NC236, the maximum of NADH-GDH and NAD-GDH appeared at 165 and 110 mmol L−1 NaCl concentration, respectively. Compared with B46, and the GOT and GPT activities of NC236 increased first and then decreased. With the increase of NaCl concentration, the contents of proline, soluble protein, and soluble sugar were increased. The Na+ content of B46 and NC236 increased, and the K+ content and K+/Na+ decreased. Compared with NC236, B46 had higher IAA content in leaf, higher Z + ZR content in leaf and root, and lower ABA content in leaf and root.

“…In their review, Kesavan et al (2013) have described the importance of phytohormones in determining seed size and as a target for breeding. Endogenous cytokinin (CK), indoleacetic acid (IAA), and abscisic acid (ABA) are positively correlated with grain-filling rate and duration (Li et al, 2020;Wang et al, 2006;Wei et al, 2019;Yang et al, 2003;Yang et al, 2004;Zhang et al, 2016). The application of CK, auxin, and ABA during the early grain-filling stage also has a positive effect on grain size and yield components.…”

“…The application of CK, auxin, and ABA during the early grain-filling stage also has a positive effect on grain size and yield components. Application of CK to rice, wheat, maize, and triticale increased the grain weight, grain-filling period, and rate (Basunia and Nonhebel, 2019; Li et al ., 2020; Panda et al ., 2018; Sivakumar et al ., 2001). Similarly, IAA treatment of rice enhanced the grain filling rate and grain weight (Yang et al ., 2003; Zhang WY et al ., 2016).…”

Teff is an Ethiopean cereal that has the potential for increased global production. However, as a very small-seeded grain, it experiences high levels of post-harvest loss. As ethylene is reported to have a negative effect on grain size, this study sought to test whether 1-methylcyclopropene (1-MCP), an ethylene action inhibitor, is a suitable molecule to improve grain size of teff as well as to determine the optimum application time and concentration. The 1-MCP treatment was evaluated on well-watered plants as well as plants subjected to moderate water stress, with the stress treatment imposed one week before the expected flowering date. Application of 1 PPM 1-MCP to individual panicles improved grain size and thousand-grain weight (TGW) by 22% and 29% under moderate water stress and 10% and 16% under well-watered conditions, respectively. It also increased yield per panicle. However, when applied to whole plants it was not effective, due to the extended flowering time of teff and differing responses of panicles at different developmental stages. These observations suggest that genetic modification leading to lower production of endogenous ethylene could benefit grain size in teff. However, 1-MCP treatment is unlikely to be effective in the field. Keywords: grain size, TGW, 1-MCP, teff, panicle, yield-related traits
