ABSTRACT

This study was conducted to obtain basic data related to the seeds, germination conditions, and physiological changes in the seeds of Thalictrum uchiyamae Nakai (Seoul Meadow Rue). The seed was elongated and tapering at both ends, and its length and width were 1.810–2.744 and 0.576–0.989 mm, respectively. When the seeded seeds were planted immediately, the germination rate was less than 5% at 15/6°C or 20/10°C, but after cold stratification for 8 weeks at 5°C, the germination rate exceeded 80% at 30/20°C, 20/10°C, and 15/6°C. Thus, it was confirmed that T. uchiyamae seeds are morphophysiologically dormant. The physiological changes in the seeds during cold stratification were investigated in terms of proteomics; the number of activated proteins increased from 330 to 353 after cold stratification. We confirmed that the disappearance of or decrease in tunicamycin and phytochrome is associated with the breaking of dormancy in T. uchiyamae seeds.
