  • 초록

    We tested various pretreatments to enhance the germination of `Sea bells' (Calystegia soldanella Roem. et Schult). One experiment, which improved the germination rate by 70%, involved first scarifying the seed coats, then immersing the seeds in 50 ppm $GA_3$ for 24 h. A $GA_3$ -alone pretreatment did not increase germination. However, the most effective method, with a 100% success rate, included 3 h of acid pretreatment with 98% $H_2SO_4$ . We also used scanning electron microscopy (SEM) to examine the seed-coat surfaces and cross-sections of dry seeds. SEM showed structural differences between seeds that were not treated and those exposed to 98% $H_2SO_4$ . The latter treatment allowed the seed coats to crack and break, thereby disrupting their physical dormancy.
