초록

Background : Cynanchum wilfordii is a perennial species of climbing vine belonging to the family Asclepiadaceae. Cynanchum wilfordii native to Korea has been cultivated and used for medicine with tuber root. Direct seeding and seedling transplanting and tuber root seed (below ∅10 ㎜) planting have been performed for cultivation. This experiment was carried out to investigate growth and yield characteristics of Cynanchum wilfordii according to planting method.
Methods and Results : Direct-seeding and tuber root seed (TRS) planting were performed in early April and seedling transplanting with seedling grown for 40 days was performed in early may. TRS size was 2 – 3 ㎝ in length and 10 ㎜ and 20 ㎜ in diameter respectively. Seedling establishment rate was similar as 97.3% - 99.0% in all treatments. Vine length, branch number, node number and chlorophyll content were not significantly different in all treatments. Stem diameter, leaf length, and leaf width were higher in TRS planting. Main root number was more as 4.5 - 4.3 in seedling planting and TRS planting (∅20 ㎜) respectively but first lateral root number was not significantly different in all treatments. Root diameter was thicker as 23.3 ㎜ in TRS planting (∅20 ㎜). Total yield in TRS planting (∅20 ㎜) was higher as 1,041 ㎏/10 a, 25% increased compared to 830 ㎏/10 a of direct seeding and with higher commercial yield rate of 75.7%.
Conclusion : It was considered that higher total yield and commercial yield in TRS planting (∅20 ㎜) was resulted from bigger size of stem diameter, leaf length, and leaf width and bigger main root size related to root yield and commercial value.
