아피오스(Apios americana M.) 도입 생산을 위한 기초 연구

Abstract

Newly introduced two lines of apios (Apios americanaMedikus, red-vine and green-vine)were grown in Jeju island, to clarify their growth and production characteristics as well asto develope as a new edible crops in Korea. Both lines bloomed but did not develop to podand seed. The red- viny line showed the habit of more early growth and maturity comparedwith green-viny line. Fresh tuber yields per 10a harvested in late November ranged fromabout 500㎏to 800㎏as according to the lines and cultural condition. Fresh tuber yield ofred-viny line was relatively greater than that of green-viny line, mainly due to their highertuber number per plant. Among the planting dates(April 1, April 16 and May 1) of seedtubes, highest tuber yield was obtained on May 16 planting. And the stacking cultivationculture was better than non-stacking cultivation in respect of tuber yield and diseaseavoidance. These results indicate that apios can produce in Jeju island, and in order toextend its cultivation to farmers it will be needed to develope some cultivars with high yieldsas well as labor-saving cultivation methods.
