Abstract

This experiment was conducted to select the right artificil soil for the purpose of artificial cultivation by effect of NaCl and different artificial soil treatment on plant growth in Salicornia herbacea that live in coastal areas. The experimental plants were planted in light and easy-to-use artificial porous soil, vermiculite, perlite, and mixed soil and were cultured for 4 month treated by hyponex solution fertilizer and 200 mM NaCl. The height, fresh weight, and dry weight of plant growth was good in a mixed soil of porous soil and pearlite. NaCl treatment on growth and chlorophyll contents, regardless of soil type decreased. Proline content of control was showed higher than salt treatment in planted by poros soil and perlite and antioxidant activity was similar value in all treatment. The antioxidant of Salicornia in different soil and salt treatment was not affected.

해안지대에 서식하는 염생식물인 퉁퉁마디의 염처리와 인공토양에 따른 생육반응을 조사하여 시설 내 인공재배상에 적합한 토양을 선발하고자 본 연구를 실시하였다. 토양은 가볍고 인공재배상에서 이용이 간편한 난석, 버미큘라이트, 펄라이트 및 혼용처리로 하였으며 염처리는 NaCl 농도를 200mM로 처리하였으며 복합비료를 시비하여 4개월간 재배하였다. 초장, 생체중, 건물중에 있어서 식물 생육은 다공성 난석과 펄라이트를 혼합한 토양에서 생육이 좋았으며 NaCl 처리 시 생육과 엽록소 함량은 토양종류에 관계없이 감소하였다. 프롤린 함량은 보습성이 낮은 난석과 펄라이트의 경우 대조구 값이 염처리에 비해 높은 것으로 나타났다. 항산화활력은 처리별 그 차이가 거의 없었고 퉁퉁 마디의 경우 염처리가 항산화물질의 증가에 영향을 미치지는 않는 것으로 나타났다.
