Abstract: | Several-years-old callus tissue derived from mature embryos of endive (Cichorium endivia Linn., Compositae) was grown on synthetic liquid and/or agar nutrient media. Incorporation of yeast extract or high concentrations of inositol, kinetin, casein hydrolysates (pancreatic and acid hydrolysates), etc., improved growth and organ formation. Rosettes of leaves, shoots and roots were differentiated on synthetic media. On agar media shoots arose first and were from marginal meristematic areas, while the roots arose later and were from pockets of meristematic tissue located in the deeper regions of the callus. In liquid media embryoids from single cells were formed which first developed roots and then shoots. |
