Proteomic analysis of tree peony (Paeonia ostii 'Feng Dan') seed germination affected by low temperature.

Seed germination is a critical process that is influenced by various factors. In the present study, the effect of low temperature (4 °C) on tree peony seed germination was investigated. Compared to seeds maintained at 25 °C, germination was inhibited when seeds were kept at 4 °C.
