Abstract

This study was conducted to clarify the effects of the different substrates in terms of perlite (100%), peat moss (100%), granular rock wool (100%) and mixing perlite (50%) with peat moss (50%) on the growth responses and mineral contents of hydroponically grown Plantago asiatic in aggregate culture. Overall early plant growth such as plant height, stem diameter, number of leaves, root length, fresh and dry weight of shoot and root were increased in the order of that miked perlite and peat moss (50%:50%, v/v)>peat moss (100%)>granular rock wool (100%)>perlite (100%). Ca and Mg contents in plants became highest in the plants grown in the peat moss, however, Mg and Na in the granular rock wool. $P_2O_5$ content in plants were most increased in proportion to the plant growth increment in the peat moss (100%) and the mixing substrates of perlite and peat moss (50:50, v/v).

질경이를 공시하여 펄라이트, 펄라이트와 피트모스 1:1 혼합, 입상암면 및 피트모스 등 4종의 고형배지경에서 배지에 따른 생장반응과 무기성분 함량을 비교 분석하였다. 배지종류별 생육반응은 초장, 경경, 엽수, 최대근장, 지상부와 지하부의 생체중 및 건물중 등 전반적인 초기생장이 펄라이트와 피트모스 혼합배지>피트모스 배지>입상암면 배지>펄라이트 배지 처리구 등의 순인 것으로 나타났다. 식물체내 Ca와 Mg함량은 피트모스 배지에서, Mg와 Na 함량은 입상암면 배지에서 가장 높은 것으로 나타났다. 식물체내 $P_2O_5$ 함량은 식물 생장과 비례적으로 증가하여 펄라이트와 피트모스 1:1 혼합 배지 처리구와 피트모스 배지 처리구에서 높게 나타났다.
