Possibilities and limits of micropropagation in relation to virus-freeing in ornamental plants. [Conference paper].

Oertel C.
From the sphere of in-vitro culture of ornamental plants are chosen three approaches that are of interest to the virologist within the framework of maintaining selection, namely-meristem culture, axillary budding and callus culture. Some problems of meristem culture are discussed and the difficulties encountered in virus-freeing referred to, with the aid of examples from chrysanthemum, carnations, pelargoniums and freesias. Only with heat therapy, meristem culture and testing combined in a closed circulation can satisfactory results be expected. The in-vitro methods are compared with the traditional horticultural propagation methods and their efficiency limits discussed. By example of freesias, the reasonable combination of virus-freeing through meristem culture and testing with subsequent in-vitro propagation is demonstrated.
