Abstract

Addition of growth inhibitors such as ancymidol, ABA, chloromequat, and pachlobutrazol into MS medium had no effect to preventing vitrification in cultures of Rehmania glutinosa. Anatomical investigation revealed that vitrified thick leaf tissue in vitro had larger intercellular space with poor development of sponge and pallisade tissue compared to those of in vitro grown glaucous and field grown plants. In vitro grown glaucous leaf had smaller and round type stomata showing distinguishable guard and subsidiary cell than those of reestablished plantlets into soil whereas abnormal stomata and poor development of epicuticular wax on the surface of leaf was observed in verified plantlet.

배지내 생장억제제의 첨가는 투명화 방지에 효과가 없었다. 기내에서 생산된 건전묘와 투명화묘에 있어서 잎과 기공의 구조적 및 형태적 특징을 조사해본 결과 기내건전묘나 포장활착묘는 책상 및 해면세포의 발달이 양호하고 세포간극이 차지하는 면적이 적었으나 기내 투명화묘는 책상세포의 발달이 불량하고 세포간극이 차지하는 면적이 현저히 많았다. 기공의 특성을 조사해본 결과 기내 건전묘는 포장활착묘에 비해 기공의 크기가 작았으며 둥근형태를 띄고 있었으나 투명화묘에 비해 공변세포와 부세포의 구별이 명확하였다. 또한 투명화묘에서는 기공의 형태가 비정상적이었고 표피 왁스의 발달이 전혀 관찰되지 않았다.
