Abstract: Chrysanthemum is the one of popular houseplants commodityies from subtropical regions and it have already widespread in Indonesia, moreover it begins to develop from plateau untill lowland. One of the problems in the lowland is a slight decrased quality of the flower. Giving improvement of the chrysanthemum flower quality in the medium plain, it used the suitable seeds. During this time, there is no available special variety of chrysanthemum flowers for medium plain and lowland, even though chrysanthemum flower has developed in many lowlands in Indonesia. The technology which was used for PEG osmolitikum (Poly Ethylene Glycol) in tissue culture can be used for marking the flowers which could be growth either in high temperature or low temperature. The main purpose of this research is a quantitative research investigation for the variety of explants and the optimal compotition of matter to stimulate the plantlet regeneration post irradiation and PEG grapped. The method that was used for this research is examining ZPT dosis thought several explants which had already irridated and grapped by gamma ray an PEG. The result of this research showed that chrysanthemum plantlets was stimulated with ZPT IAA+1.5 ppm 0.5 ppm BA throught the corner explants to stimulate growth of shoot height, leaf, root number and root length.
