Abstract

The purpose of this study was to identify the propagation characteristics of Diabelia spathulata (Siebold & Zucc.) Landrein through seeding and cutting methods. The seed germination rate was meager (0.22~3.56%). In hardwood cutting, the highest rooting rate was 36.1% in sand + perlite (2:1) and 37.8% in 1000 PPM of IBA pre-treatment. Softwood cutting showed the highest rooting rate when the cutting diameter was 3 to 5 mm and the cutting length was 7 to 8 cm. In particular, the highest rooting rate of 80% was observed in the sand among the 8 cultivation media treatments. In the case of root cuttings, the rooting rate was 83.3~96.7% in all cultivation media. The highest rooting rate was observed when the diameter of the cutting was 7 to 8 mm, and the length of the cutting was about 10 to 11 cm. Among cutting methods, root cutting showed the highest rooting rate. Division showed a 100% rooting rate regardless of size or growth status. For Diabelia spathulata (Siebold & Zucc.) Landrein, propagation by cuttings was more efficient than seeding. However, Further research on the morphophysiological dormancy and dormancy break of seeds is needed for seed propagation.

희귀식물인 주걱댕강나무를 보전하기 위해 종자파종과 삽목을 중심으로 증식 특성에 관한 실험을 수행하였다. 종자파종의 발아율은 노천매장 저장에서 3.56%, 모래 배양토에서 2.44%이나, 이는 극히 낮은 발아율로 증식을 위해 종자의 활력검정, 휴면성 타파 등과 같은 종자의 특성에 관한 연구가 필요할 것으로 판단된다. 숙지삽은 모래(2)+펄라이트(1) 조합에서 36.1%의 발근율로 가장 높게 나타났으며, 삽수의 발근촉진제 처리는 IBA 1000 ppm에서 발근율이 37.8%로 가장 높았고, 신초의 길이, 뿌리 수, 뿌리 길이는 발근촉진제 처리와 함께 농도가 높아질수록 높게 나타나는 것을 확인하였다. 녹지삽은 모래에서 80% 발근율로 가장 높지만 캘러스 형성이 93.3%임에도 불구하고 발근율이 80%로 떨어지고 있음을 확인하였다. 녹지삽을 수행할 경우 삽수의 직경은 3~5 mm 정도를 권장하며, 삽수의 길이는 7~8 cm가 적정하여 직경이 굵으면서도 길이는 플라스틱 육묘용 상자 높이 보다 낮게 삽수를 조제하는 것이 효율적일 것으로 판단된다. 근삽의 경우 모든 배양토에서 83.3~96.7%로 삽목 방법 중 가장 높은 발근율을 보였다. 그 중 모래보다는 혼합용토가 효율적임을 확인하였으며, 모든 삽수에서 발아율이 90%를 상회할 정도로 높았다. 삽수의 직경은 7~8 mm에서 100%, 삽수의 길이는 10~11 cm와 같이 길어질수록 발근율과 지하부, 지상부 모두에서 생육이 왕성하였다. 분주의 경우 직경이 커질수록 생장이 왕성하나 분주목의 크기나 생육상태에 관계없이 100% 활착률을 보였다. 이상을 종합해 보면 주걱댕강나무는 종자파종보다 삽목이 효율적이며, 그 중 근삽과 분주의 활착률이 더욱 높은 것으로 판단된다. 그러나 종자번식에 대해서는 종자의 형태생리적 휴면, 휴면타파 등에 관한 후속 연구가 필요할 것으로 판단된다.
