Stimulation of Seed Germination at Suboptimal Temperatures through Biopriming with Biofilm-Forming PGPR KT2440.

This study investigated the germination response to temperature of seeds of nine ecotypes. They are characterized by a similar temperature dependency of seed germination, and 10 °C and 29 °C were found to be suboptimal low and high temperatures for all nine ecotypes, even though they originated from regions with diverse climates. We tested the potential of four PGPR strains from the genera and to stimulate seed germination in the two ecotypes under these suboptimal conditions.
