Abstract

We have also clarified the effects of the different substrates; (perlite, peatmoss and granular rock-wool) on the plant growth and the mineral contents of Campanula takesimana until 70 days after transplanting. Overall plant growth in terms of plant height, stem diameter, number of leaves, root length, fresh and dry weight of shoot and root were increased in the order of that mixed perlite and peat moss (50 : 50, v/v)>peat moss (100%)>perlite (100%)>granular rock wool (100%). Mineral contents in plants were much more in the order of potassium $(15.38-43.91cmol^+/kg)$, calcium $(5.48-7.78cmol^+/kg)$, magnesium $(4.38-6.55cmol^+/kg)$ and sodium $(1.25-1.69cmol^+/kg)$. The higher mineral contents of plants were also most made in the mixed substrates of perlite and peat moss (50 : 50, v/v).

섬초롱꽃을 공시하여 4종의 고형배지(펄라이트 1호 단용, 펄라이트 1호와 피트모스 1 : 1 (V : V)혼용, 입상암면 단용 및 피트모스 단용 배지)에서 70일간 재배하면서 배지에 따른 생장반응과 무기성분 함량을 비교 분석하였다. 생육반응은 초장, 경경, 엽수, 근장, 지상부와 지하부의 생체중 및 건물중 등 전반적인 부분에서 펄라이트와 피트모스 1 : 1(v : v) 혼용 배지 >피트모스 배지 >펄라이트 배지 >입상암면 배지 처리구 순으로 좋게 나타났다. 식물체내 무기성분은 $K(15.38-43.91cmol^+/kg),\;Ca(5.48-7.78cmol^+/kg),\;Mg(4.38-6.55cmol^+/kg),\;Na(1.25-1.69cmol^+/kg)$ 순으로 많았다. 무기성분 함량은 생육이 우수한 것으로 나타난 펄라이트와 피트모스 혼용 처리구에서 재배한 섬초롱꽃에서 많게 나타났다.
