Abstract

Leaf Anatomy Characteristic of Pruatjan Cultures Post In Vitro. Evaluation of anatomical characteristics regenerant planlet of purwoceng (Pimpinella pruatjan Molk.) cultivated on conservation medium was observed to determine the difference of characteristics performance of the planlet grown on conservation medium and those that was maintained on the normal medium. Stomata was microscopically observed on abaxial leaf paradermal section that preparated by whole mount method and leaf structure on cross section by paraffin method. The result showed that stomata density was greater on the planlets regenerated in the conservation medium but stomata length was lower than those on the normal medium. Upper epidermis, mesofil and lower epidermis length of the regenerant on the conservation medium were lower than those on the normal medium. Sorbitol and paclobutrazol applied reduced the performance of regenerated spesies than those of planlet maintained on the normal medium. Combination of both application resulted in anatomical character differences on the plants regenerated on normal medium.
