The effect of methanesulfonic acid (MSA) on the morphophysiology and biochemistry of the subantarctic species Colobanthus apetalus and the Antarctic species Colobanthus quitensis was examined. We evaluated the effects of various concentrations of MSA on the germination capacity and germination rate of seeds, seedling growth, chlorophyll fluorescence in cotyledons, and the proline content of seedlings under laboratory conditions at temperatures of 20°C (day) and 10°C (night) with a 12/12 h photoperiod. The examined C. apetalus seeds were grown in a greenhouse, and C. quitensis seeds were harvested in Antarctica and grown in a greenhouse (Olsztyn, Poland). The seeds of C. apetalus were characterized by the highest germination capacity and the highest germination rate, whereas C. quitensis seedlings were characterized by the most favorable growth and development. Only the highest concentrations of MSA decreased the intensity of chlorophyll fluorescence in the cotyledons of both Colobanthus species. The proline content of C. apetalus and C. quitensis seedlings increased significantly after MSA treatments. The results of this study clearly indicated that Colobanthus quitensis is more resistant to chemical stress induced by MSA. This is a first study to investigate the influence of MSA on the morphophysiology and biochemistry of higher plants.
