초록

This study was conducted to examine the vitality of Bletilla striata Rchb.f. seed treated with different concentrations sodium hypochlorite (NaOCl) for different lengths of time. This study also examined the effect of NaOCl treatment times and concentrations on swelling formation and seed germination of B. striata seed. The non-treated B. striata seed had the highest survival rate (82.7%) Treatment with more than 1.5% NaOCl negatively affected the seed survival rate, as compared to concentrations of less than 1%. The swelling formation and seed germination percentages were highest (90.1% and 94.1%, respectively) when seeds were treated with 0.5% NaOCl for 20 min. These results can be used as important basic data for the growth and restoration of B. striata and further suggest the possibility of individual restoration in habitats.
