본 연구는 항암식물로 효능이 인정되는 와송에 대한 기초적인 연구로 와송의 해부형태적 관찰, 대량증식을 위한 발아실험, 자생지의 토양분석 및 토양적응실험을 실시하였다. 와송의 잎은 끝에 가시가 있는 건생형이며, 엽세포엽록체는 유관속주위에 집중분포하고, 크고 엽록체를 갖지 않는 저수조직을 갖고 있으며 기공이 양면에 있는 양면기공엽이다. 줄기는 외사포위형유관속이며 중심주는 원기둥상이고 원생중심주이다. 뿌리는 다원형이며, 원생목부가 후생목부주위에 환상으로 배열되어 있고 외원형이다. 꽃의 구조는 꽃잎이 5개, 수술은 10개, 자방은 5개이며, 자방상위이고, 2심피 중축태좌이다. 와송종자 발아적온는 명상태 25℃ 에서 22.5%로 가장 좋았고, 휴면타파는 5℃ 에서 6~8일, GA3 100 ppm처리에서 가장 효과가 좋았다. 와송 자생지 토양분석결과 적정수준의 밭토양보다 유기물, 유효인산 석회 등은 높았고, 보비력, 치환성가리는 차이가 없었으며, 고토는 낮았다. 토양적응실험에서 돌가루 조합과 기와가루 조합에서 돌가루와 기와가루가 많이 첨가될수록 생육상태가 불량하였고, 배수가 양호한 처리구에서는 생육상태가 양호하였다.
Wasong(Orostachys japonicus A. Berger) has been used as anti-cancer medicinal plants from ancient time. This experiment was conducted to obtain some fundamental informations concerning anatomical study, germination test, soil analysis of indigenious districks, adaptaion of soil for wasong. The leaf of wasong was xerotype with spine, mesophyl chloroplast is dense surrounded vascular bundle, with a many large water storage tissue without chloroplast, and was bifacial stomata leaf type. The stem of wasong was amphicribral vascular bundle, central cylinder was cylinder type and protostele. Root was polarch type, potoxylem of it's was arranged in ring shape of annulation and metaxylem. The structure of flower was cymose, was caylyx of 5 sepals, corolla of 5 petals, roecium of 10 stames, ovules of five, placentation parietal, ovary superior, axile placenta. The optimum temperature for seed germination was 25~circC under light and germination percentage was 22.5%. Dormancy breaking was effective for 6-8 days at 5~circC and at 100 ppm level of GA3 The soil analysis of wasong local districks, content of available P2O5 , Ca were higer than optimal level of upland and C.E.C., exchangeable k was not significantly different of that, but exchangeable magnesium was very low. The growth of wasong was affected draining regardless soil combination treatment.
