Abstract

This study aimed to select the media for water flooding culture of Pinus thunbergii Parl., Juniperus chinensis L. var. sargentii Henry, Osmanthus fragrans Lour., and Chaenomeles japonica Lindl. ex Spach planting into quartz Porphyry and Hydroball. The survival rate of Pinus thunbergii Parl. and Chaenomeles japonica Lindl. ex Spach in hydroball 80%+quartz porphyry 20% was 100%, also the ratio of Juniperus chinensis L. var. sargentii Henry and Osmanthus fragrans Lour. in hydroball 20%+quartz porphyry 80% was 100% and 80%. However survival rate of full water and decomposed granite was less than 80% in Pinus thunbergii Parl., Juniperus chinensis L. var. sargentii Henry, and Chaenomeles japonica Lindl. ex Spach and thee rate of Osmanthus fragrans Lour was less than 50%. The increasing rate of fresh weight for Pinus thunbergii Parl. and Chaenomeles japonica Lindl. ex Spach in hydroball 80%+quartz porphyry 20% was 58.6% and 15.8% which was higher than others, and the fresh weight was increased as increasing the content of hydrobol. However the fresh weight of Juniperus chinensis L. var. sargentii Henry and Osmanthus fragrans Lour. in hydroball 20%+quartz porphyry 80% was 71.4% and 59.7% which was higher than others, and the fresh weight was increased as increasing the content of quartz porphyry. The increasing rate of fresh weight of decomposed granite as control was the lowest by 32.7%, 48.0%, 33.3% and 7.0%, respectively in Pinus thunbergii Parl., Juniperus chinensis L. var. sargentii Henry, Osmanthus fragrans Lour., and Chaenomeles japonica Lindl. ex Spach. Therefore the survival rate and fresh weight was lower at water and decomposed granite. However the survival rate and increasing fresh weight of Pinus thunbergii Parl. and Chaenomeles japonica Lindl. ex Spach was higher as increasing the rate of hydrobol. And the survival rate and fresh weight of Juniperus chinensis L. var. sargentii Henry and Osmanthus fragrans Lour was higher as increasing the rate of quartz porphyry.

담수재배 시 배양토로 하이드로 볼과 맥반석의 부피 비율이 도자기 분 식물의 생장에 미치는 영향을 알아보기 위하여 해송(Pinus thunbergii Parl), 진백(Juniperus chinensis L. var. sargentii Henry), 목서(Osmanthus fragrans Lour.), 장수매(Chaenomeles japonica Lindl. ex Spach) 등 4종에 대하여 실험을 하였다. 배양토 비율에 따른 해송, 진백, 목서, 장수매의 생존율은 해송과 장수매는 하이드로볼 80% + 맥반석 20%에서 100%였으며 진백과 목서는 하이드로볼 20% + 맥반석 80%에서 100%와 80.0%로 높은 생존율은 보였으나 대조구인 물 및 마사토의 생존율은 해송, 진백, 장수매에서 80%이하의 생존율을 보였으며 특히 목서의 경우 50%이하의 낮은 생존율을 보였다. 배양토 비율에 따른 생체중 증가율은 해송과 장수매가 하이드로볼 80% + 맥반석 20%에서 각각 58.6%와 15.8%로 가장 높았으며 하이드로볼의 함량이 증가할수록 생체중 증가율이 높은 것으로 나타났다. 진백과 목서의 경우 하이드로볼 20% + 맥반석 80%에서 생체중 증가율이 각각 71.4%와 59.7%로 높게 나타났으며 맥반석의 함량이 증가할수록 생체중 증가율이 높아지는 것으로 나타났다. 대조구인 마사토의 생체중 증가율은 해송, 진백, 목서, 장수매에서 각각 32.7%, 48.0%, 33.3%와 7.0%로 가장 낮은 생체중 증가율을 보였다. 이와 같이 담수재배 배양토로 대조구인 마사토는 낮은 생존율과 생체중 증가율을 보였다. 하지만 하이드로볼의 비율이 높아질수록 해송, 장수매는 생존율과 생체중의 증가율이 높게 나타났고 맥반석의 비율이 높아질수록 진백, 목서의 생존율과 생체중은 높았다.
