an in vitro plant regeneration protocol was successfully established in aphyllorchis montana , a saprophytic achlorophyllous orchid by culturing immature seeds. among the six basal media evaluated for seed germination, bm-tm medium was found to be the best followed by kc medium. after 40 days, all the media turned brown and the growths of the protocorms were arrested. activated charcoal, 1 g/l ...

Lilium ledebourii (Baker) Boiss. (Liliaceae) is a critically endangered lily species native tonorthern Iran, where it is protected by law. In order to develop a cost effective method for largescalepropagation, the effects of three culture systems (solid, liquid and temporary immersion)and two types of cytokinins [6-Benzyladenine (BA) and Thidiazuron (TDZ)] were studied onthe in vitro plant rege...

Subinhibitory concentrations of the neuroleptic drug thioridazine (TDZ) are well-known to enhance the killing of methicillin-resistant Staphylococcus aureus (MRSA) by β-lactam antibiotics, however, the mechanism underlying the synergy between TDZ and β-lactams is not fully understood. In the present study, we have examined the effect of a subinhibitory concentration of TDZ on antimicrobial resi...

gavane-gaz-angubin (persian manna) belongs to astragalus genus (leguminosae). this plant is one of the most important species in iran for its medicinal value. considering the low propagation rate of this plant from seed and cutting, the feasibility of in-vitro propagation of this plant was investigated. effect of different types and concentrations of cytokinins such as bap, kin, and ze (0.5, 1,...

Thidiazuron (1-phenyl-3(1,2,3Thiadiazol-5-yl) urea; TDZ) is one of the several substituted ureas that have been investigated recently for their cytokinin-like activity. TDZ is known to be more active than zeatin for stimulating the growth when added to a tissue culture medium at a low concentration. In this study, effect of TDZ on several In vitro growth parameters in Solanum tuberosum cvs. Des...

The gerbera market would benefit from an efficient and simple protocol for high rate regeneration for propagation and genetic engineering. With these objectives, this investigation was done on shoot regeneration via direct organogenesis from leafy petiole explants of Gerbera jamesonii ‘Royal Soft Pink’. Murashige and Skoog (1962) (MS) medium was supplemented with 0.1 mg L-1 indole-3-acetic acid...

Annona glabra is a tropical species that has significant agronomic potential in terms of furnishing fruits for in natura consumption and for the production of phyto-pharmaceuticals. In vitro cultivation has been considered the most promising form of propagation for this species, although large scale utilization of this technique is currently limited by high rates of leaf abscission, reduced rat...
