Abstract

e checked the emergence rate and early growth characteristics of young rice plants according to the germination length and seed damage ratio in direct seeding. The emergence rate was reduced according to the longer germination length and higher seed damage ratio. The emergence rate was further reduced under high-temperature conditions. The leaf number did not show a significant difference according to germination length and seed damage ratio. However, shoot and root dry weights were reduced according to the germination length and seed damage ratio. The root dry weight was highly correlated with the shoot dry weight. Based on these results, we concluded that a longer germination length and seed damage could induce the loss of nutrients and affect poor root growth, consequently inducing poor emergence and growth in the early growth stage of rice seeds. Therefore, in rice direct seeding, seed conditions of less than 1 mm of germination length should be checked for a sufficiently high standing rate and adequate growth characteristics after seeding.
