열대란중의 한 종인 헤마리아의 생장점배양을 통하여 기내에서 유묘를 대량증식 시키고자 몇가지 배양조건에 관해서 검토하였다. 생장점 초기배양용 배지는 MS배지에 비해 H$_3$P$_4$배지에서 생존율이 전반적으로 양호하였으며 H$_3$P$_4$배지 에 kinetin 1.0 mg/L를 단용한 배지에서 생육상태가 양호하였다. 유묘의 증식은 줄기(의구경) 상부의 마디를 포함한 줄기를 2분할하여 H$_3$P$_4$배지에 2ip 0.1 mg/L kinetin 0.1 또는 1.0 mg/L를 단용한 배지에서 명배양했을때 액아로부터 줄기의 신장이 가장 양호하였다.

The experiments were conducted to obtain culture conditions on optimal cultural conditions for propagation of a topical orchid, Haemaria discolor, through shoot tip cultrue in vitro. Survival percentage of shoot tip explant, in initial culture media was higher in H$_3$P$_4$ medium than in Murashige and Skoog's medium. Explants, cultured in H$_3$P$_4$ medium containing 1.0 mg/L kinetin, showed more shoot elongation when compared with those on other media. When the distal part of stem (pseudobulb) was longitudinally sectioned into half and cultured in H3P4 medium containing 0.1 mg/L 2ip, 0.1, or 1.0 mg/L kinetin, shoots from axillary bud were much more elongated under light condition.
