A minimal cost micropropagation protocol for Dianthus caryophyllus L.-- a commercially significant venture.

In tissue culture, high production cost of the products restricts their reach. Though tissue culture is a major strength in floriculture it is marred by pricing issues. Hence, we developed a complete regeneration low cost micropropagation protocol for an economically important floriculture crop, carnation (Dianthus caryophyllus L.). Successful regeneration of carnation from nodal explants on cost-efficient medium indicates that psyllium husk, sugar and RO water can effectively replace the conventional medium comprising agar, sucrose and distilled water. The protocol can contribute to increased carnation production at comparatively reduced cost, and there by encourage wide scale adoption by the common growers.
