Seed Germination and Physiology

Hungary is northernmost temperate rice growing country in Europe. One of the main limiting factors is low temperature, especially at germination and seedling developmental stages. In early developmental stages, low temperature can impair and delay germination, as well as have negative impacts on seedling growth, causing poor stand establishment and non-uniform crop maturation [1]. Temperatures lower than 15 °C are generally detrimental for germination [2] under filed conditions for establishment of the crop. This article describes some key germination parameters of 165 rice accessions including breeding lines and varieties. Each genotype was grown in three replicates in a controlled cabinet under 13 °C for 4 weeks' duration. Growth was measured every 7th day. Growth traits such as coleoptile and radicle length were measured at the end of the experiment. The average data were calculated for three replicates. This dataset contains germination raw data and five germination parameters such as median germination time (MGT), final germination percentage (FGP), germination index (GI), coleoptile length (CL) and radicle length (RL). These data may provide reliable support for researchers and breeders to select the right rice genotypes for low temperature conditions.
