Summary
Heterospecific chimeralSolanum nigrum (+)Solanum tuberosum plants were obtained by cell grafting in protoplast co-cultures. Periclinal, sectorial, and mericlinal chimeras have been identified by various morphological and cytological characteristics.
Morphogenesis predominantly began in periclinal chimeral organization. Cells of different species have been found to be interconnected by secondary plasmodesmata. Plantlets of all chimeral lines were grown to flowering under tissue culture conditions and some also in the greenhouse. Aspects of organogenesis and interspecific cooperation are discussed.
