Poor crop establishment of direct-seeded rice (DSR) is one of the major constraints to wide adoption of DSR, particularly in areas prone to flooding after sowing or where fields are not level. Seed pelleting is an effective, practical and facile technique to enhance crop establishment under unfavorable environmental conditions. To evaluate the effects of seed pelleting on rice germination, seedling growth and associated metabolic events under waterlogging stress, various seed pelleting treatments including formulae, pelleting times (the weight ratio of pelleting agents: rice seeds = 1:1~7:1 (w/w) and CaO2 contents were tested in series of experiments. Naked seeds were maintained for comparison as a control. Pelleting treatments with CaO2 significantly increased seed germination and seedling growth of DSR under waterlogging conditions compared with pelleted seeds without CaO2 and naked seeds. The optimum weight ratios of CaO2 to dry seeds were found to be in the range of 0.6:1–1:1 based on seed germination and seedling growth performance under waterlogging conditions. Under waterlogging conditions, high seed germination percentage and vigorous seedling growth of DSR due to seed pelleting with CaO2 was associated with an increase in α-amylase activity, but decrease in alcohol dehydrogenase (ADH) and pyruvate decarboxylase (PDC) activities in pelleted seeds.

“…Previous studies have shown seed coating technology to be an effective approach for improving seed germination and seedling growth of crop plants (Taylor et al, 2001). In rice, seed coating improves the performance and physical properties of seeds, especially under adverse environmental conditions (Baker et al, 1987;Sono et al, 1991;Tylor et al, 1998;Manjunatha et al, 2008;Zeng et al, 2009). Seed coating with salicylic acid, paclobutrazol or humic acid has a positive effect on seed germination and seedling growth in maize (Lan et al, 2008;Wang et al, 2010;Zhu et al, 2013).…”

“…According to one study, the performance and physical properties of rice seeds are improved by coating them with liquid-based polymeric adhesives (Zeng et al, 2009). In addition, the oxygen provided to rice seeds planted under anoxic or near-anoxic soil conditions is increased when seeds are coated with peroxide compounds (Baker et al, 1987;Sono et al, 1991). Furthermore, germination and survival rates of seeds under adverse environmental conditions are promoted by coating with polymers incorporating pesticides (Taylor et al, 2001;Manjunatha et al, 2008).…”

To evaluate the potential effectiveness of plant growth regulators in improve seed germination and seedling vigor when applied during seed coating in sweet corn. 6-benzylaminopurine (6-BA), 1naphthalene acetic acid (NAA), brassinolide and gibberellic acid (GA 3 ) were added as seed coating agent, and seed germination, antioxidant capacity and seedling vigor of sweet corn were investigated. The results showed compared with the use of coating agent alone, plant growth regulators improved seed vigor and germination, especially GA 3 (200 and 250 mg L −1 ) and 6-BA (20 and 40 mg L −1 ) were added. Furthermore, 200 mg L −1 GA 3 treatment improved seed germination and antioxidant capacity and resulted in sweet corn seedlings with a better appearance. The results observed indicated plant growth regulators might be valuable agents in sweet corn seed coating.
