Abstract


In was found that peptone of Peptobak-Bacutil brand (produced in Poland fulfills perfectly the requirements in cultures in vitro of the meristem tissues of Cymbidium in the modified Tsuchiya's medium in a concentration of 2 g per 1. A decrease in the concentration to 1 g per 1. affects the growth intensity of the tissue, but an increase of concentration up to 3 g per 1. retards the transformation of protocorms into the plant-stage. Growth of the meristem tissue of Cymbidium in the medium consolidated with agar is weaker and the number of protocorms produced 2,3 times lower than in liquid media.
