초록

해안사구식물은 다양한 미생물과 외생균근과 내생균근의 도움으로 효과적으로 생존할 수 있다. Penicillium citrinum KACC43900를 이용하여, 해안사구식물인 갯메꽃과 갯쇠보리에 대해 생장 촉진효과를 조사하였으며, 지상부길이, 식물체길이 그리고 식물체건량을 분석하였다. P. citrinum KACC43900 배양액을 20일간 처리 시, 지상부길이는 16.30 cm와 10.56 cm이었으며, 대조구는 8.60 cm과 8.12 cm인 것을 확인 하였다. 마찬가지로 P. citrinum KACC43900 배양액을 20일간 처리 시, 갯메꽃과 갯쇠보리의 식물체길이는 24.06 cm와 17.06 cm인 것을 확인 하였고, 대조구는 14.90 cm과 14.80 cm인 것을 확인 하였다. 갯메꽃의 식물체건량은 배양여과액 처리의 경우, 0.163g이었고 대조구가 0.123 g이었다. 그리고 갯쇠보리의 식물체건량은 배양여과액 처리의 경우, 0.032 g이었으며 대조구가 0.027 g이었다. 갯메꽃과 갯쇠보리의 지상부길이는 P. citrinum KACC43900의 배양여과액에 의해 89.54%와 29.60% 촉진되었다.

Coastal sand-dune plants can survive very effectively with the help of various microbes, especially ecto- and endomycorrihizae. Penicillium citrinum KACC43900 was screened according to growth promoting activity on sand-dune plants Calystegia soldanella and Ischaemum anthephoroides. In this study, coastal sand-dune plants were treated with a fungal culture filtrate of endophytic fungus P. citrinum KACC43900 to confirm the promotion of plant growth. C. soldanella and I. anthephoroides were used as representative coastal sand-dune plants, and their shoot length, plant length, and dry weight were analyzed. The shoot lengths of control C. soldanella and I. anthephoroides were 8.60 cm and 8.12 cm, and those of samples treated with fungal culture filtrates of C. soldanella and I. anthephoroides for 20 days were 16.30 cm and 10.56 cm, respectively. The plant lengths of control C. soldanella and I. anthephoroides were 14.90 cm and 14.80 cm, and those of samples treated with fungal culture filtrates of C. soldanella and I. anthephoroides for 20 days were 24.06 cm and 17.06 cm, respectively. The dry weight of C. soldanella and I. anthephoroides treated with fungal culture filtrates of C. soldanella and I. anthephoroides for 20 days were 0.163 g and 0.032 g, respectively. It was shown that the growth of shoots in C. soldanella and I. anthephoroides was promoted, 89.54% and 29.60%, by culture filtrate of P. citrinum KACC43900.
