Callus induction and organogenesis were evaluated in the protocorm like bodies (PLB) culture of Dendrobium lineale Rolfe (Orchidaceae). The globular PLB were cultured in Murashige and Skoog (MS) medium with half strength macronutrients QA MS), supplemented with thidiazuron (TDZ 0,1, 0,5 and 1) mg/1 and 2,4 Dichlorophenoxy acetic acid (2,4-D 0.1, 0.5, 1 and 5) mg/1 as treatments. The media containing 1 mg/1 TDZ and (1 and 5) mg/1 2,4-D was the best treatment for callus initiation (100%). The largest diameter of callus was obtained from 1 mg/1 TDZ (average 3.5 cm). Shoot buds regeneration achieved on 1 mg/1 TDZ (average 41.66 %). However roots regeneration was very low (average 6.66 %) obtained from 1 mg/1 2,4-D. The number of adventitious buds produced from the regenerated shoots on media without plant growth regulator

Study on shoots growth and development of Typhonium flagelliforme (Lodd.) Blume and T. trilobatum (L.) Schott were carried out by in vitro technique.These species produce tubers are used for cancer medication; also the whole parts of plants has been reported potential for traditional medicine. Chemicals isolated from from crude extract of whole plants of T.flagelliforme are methyl esters of hexedecanoic acid, octadecanoic acid, 9- octadecanoic acid and 9,12- octadecadienoic acid.The chemical contents inhibited/decreased the proliferation of human leukaemia cell lines in test.For medical and cosmetics industrial usage of the plants requires supply materials continously of which in turn necessitate its cultivation and planting. The planting materials can be produced efficiently by micro propagation or in vitro technique. The objective of the study was to evaluate the culture respond to the plant growth regulator (PGR) treatments effect. The experiment was designed with completely randomized designed (CRD).The study was indicated that proliferation of shoot were optimum in the growth medium was supplemented with N6-Benzyladenine (BA) 1mg/l and NAA 0,5 mg/l. Acclimatization stage and planted to the soil were successful, almost whole (90-95 %) plants were survive.

Zingiberaceae species Zingiber zerumbet var. aromaticum Val. usually propagated by vegetative part of the plant. Study on the proliferation of rhizome explants through in-vitro method were conducted on this species for propagation.The explants were cultured in MS (Murashige & Skoog) composition medium in normal and half strength concentration of macro elements, supplemented with micro elements and vitamins. Plant growth regulator (PGR) cytokinin (kinetin, adenine sulphate) were added in initiation stage.Benzyl adenine (BA), thidiazuron and 2,4D (dichlorophenoxy acetic acid) added in medium as treatments to induce shoot multiplication and adventitious shoot development or rooting plants.The media for induced multiple shoot and roots (plantlets) development, supplemented with PGR BA, thidiazuron, Indole butyric acid (D3A) as treatments and activated charcoal were added as antioxidant.In general, most of cultures were indicated have positively responds to PGR treatments. The ability of culture to produce multiple shoots and roots such as in medium with BAP (8 mg/1) + thidiazuron (0.1 mg/1) + IBA (1 mg/l)-indole butyric acid would give a better opportunity of rhizome explants proliferation and plantlets development of Z. zerumbet var. aromaticum.

Caryota no Becc,(fish-tailpalm) is considered vulnerable palm, Its population is declining from the habitat by destructive exploitation but also to some extent by local people who remove the edible apex or 'cabbage 'as a vegetable and also obtain sago from the pith of the trunk,so kill the tree.A though its biological characteristics have not been fully studied,this species is also potentially for ornamental plant Thus conservation measures should be taken to improve the status of this threatened species. Tissue culture techniques may provide ways either to propagate or to conserve itin-vitro. Naturally Caryota no Becc.palm fruit after 20years and they can germinate more than 3 months after sowing with low germination value.In this experiment,the tissue culture response of this species are studied using the explant of embryo from (relatively) young fruit (juvenility fruit).The effect ofBA and 2,4D on the shoot growth, root growth and calluses was evaluated, while the evaluation of the effect ofactifated charcoal was discussed. The satisfactory results have not been achieved.
