Effects of $GA_3$ on Seed Germination and Seedling Survival Rate of Acanthopanax senticosus Maxim.

This experiment was carried out to investigate the effects of and cold stratification as presown treatments on seed germination, seedling emergence and final survival rate of Acanthopanax senticosus Maxim. Seeds collected 145 days after-ripening period followed by 10 days of cold stratification was effective in promoting germination. Dehisced seeds treated with 500 ppm of for 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 treatment than nontreatment for both dehisced and non-dehisced seeds. However, for dehisced seeds, treatment before sowing resulted in decreased final seedling survival rate.
