Abstract

Buds, planlets and bulblets formation from excised bulbscales was the preferredmethod for vegetative propagation of Lilium sp (Liliaceae). The ex vitro techniqueswith Gibberellic acid (GA3) pretreatment was induced buds formation on scalescutting which planted on sterilized sand media. Buds rised from basal scales 7days after planted. However scales untreated GA3 obtained in 35-42 after planted.In vitro methods to promote buds initiated from bulbscales explants, was inducedon media MS (Murashige and Skoog) supplemented with GA3 1 mg/l. Media forinduced buds formation, MS contained Benzyl adenine (BA) 1 mg/l and 2 mg/lincreased multiple shoots formation significantly compared cultured on mediawithout BA. Roots growth improved on media contained NAA, but the highestplanlets achieved on cultured MS media without BA. Bulblets formation obtainedon media contained higher concentration of BA (5 mg/l).

Abstract

Vegetative propagation from bulb excised of Eleutherine sp. (Iridaceae) were cultured in Murashige and Skoog (MS) medium supplemented with plant growth regulator (PGR) Benzyl adenine (BA) 1 mg/l at initiation stage, BA (2 and 5) mg/l for induced shoot buds formation at multiplication stage. In this study also BA 2 mg/l and BA 2 mg/l combined with naphthalein acetic acid (NAA) 0.5 mg/l were treated for rooting planlets formation. Calli formation were induced with auxin PGR picloram 1 mg/l combined with 2,4 dichlorophenoxy acetic acid (2,4-D) 0.5 and 1 mg/l in concentrations. The media contained 2 mg/l cytokinin (BA) without auxin (NAA), resulted the highest shoot buds formation. Rooting planlets were produced in MS medium combined with BA and NAA.MS medium contains Picloram 1 mg/l and 2,4-D 1 mg/l was optimal for frequency oncalli initiation (100%) and the largest diameter of calli also represented in cultured MS medium with picloram 1 mg/l and 2,4-D 1mg/l. In acclimatization stage, 100% of planlets survived and successfully transplanted to soil medium in the field.Key words: in vitro, Eleutherine sp.

Abstract

Sambung nyawa [Gynura procumbens(Lour.)Merr.]is one of the traditional medicine sources.The plants are not cultivated intensively in the field. One of the efforts to maintain and to propagate this species is by multiplication through tissue culture method. Nodes explants were cultured in MS normal and half strength concentration macroelements, supplemented with microelements and vitamins; combination of cytokinin BA (2 mg/1), thidiazuron (0.01 mg/1 and 0.1 mg/1) and adenine sulphate (5 mg/1).Auxin (2,4D 0.5 mg/1) in combination were added in media as treatments and activated charcoal (2 g/1) as antioxidant. Young leaves explants were also cultured in the same basic medium (MS and A MS) in treatments with cytokinin (BA and thidiazuron).The results from nodes and young leaves explant indicated that the highest number of survival cultures were obtained from combination between BA (2 mg/1) and thidiazuron (0.01 mg/1) in MS normal strength basic medium.In acclimatization stage, 100% of plantlets survived and successfully transplanted to soil medium in the field; maintenance study indicated that subculture was prolonged until 52 weeks.

Abstract

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.
