가시오갈피의 GA3처리에 따른 종자발아와 유묘생존

초록

This experiment was carried out to investigate the effects of GA₃and cold stratification as presown treatments on seed germination, seedling emergence and inal survival rate of Acanthopanax senticosus Maxim. Seeds collected 45 days after-ripening period followed by 0 days of cold stratification was effective in promoting germination. Dehisced seeds treated with 500 ppm of GA₃for 3 days was also effective in promoting germination. However, seedling emergence rate remained low in both treatment. Seedling emergence rate was higher for seeds germinated in Heungnong-Bio and Klasman-Bio than in vermiculite, perlite, vermiculite-perlite mixture, or sand. After 40 days of cold stratification, seedling emergence was significantly higher in the 500 ppm GA₃treatment than nontreatment for both dehisced and non-dehisced seeds. However, for dehisced seeds, GA₃treatment before sowing resulted in deceased final seedling survival rate.
