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 ㎝ and 8.12 ㎝, and those of samples treated with fungal culture filtrates of C. soldanella and I. anthephoroides for 20 days were 16.30 ㎝ and 10.56 ㎝, respectively. The plant lengths of control C. soldanella and I. anthephoroides were 14.90 ㎝ 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 ㎝ and 17.06 ㎝, 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.
