Shoot tip explants from germinated seeds of Alnus hirsuta were cultured on NT (Nagata and Takebe, 1971) mineral salts medium supplemented with 6% glucose, MS (Murashige and Skoog, 1962) vitamin mixture, polyvinylpyrrolidone (PVP) and $0-50;mu extrm{M}$ 6-benzylaminopurine (BAP). Five $mu extrm{M}$ BAP was found to give the highest shoot multiplication rate. Accordingly about 200 shoots were obtained for further experiments by multiplying shoots on this medium for 4-5 months. Regardless of carbon sources, NT mineral medium produced 3-12 times of shoots than MS mineral medium did. On NT mineral medium, 3% sucrose, 3% glucose and 6% glucose yielded no significant differences. It was observed that media consisting of 1/4-1/2 strength NT mineral salts, 3% sucrose and $1-8;mu extrm{M}$ IBA produced about 100% rooting rate. Almost 100% of the resulting plantlets survived after transfer to the soil by decreasing humidity stepwise.epwise.
