EXPERIMENTAL STUDIES OF YOUNG G1NKGO EMBRYOS——THE EFFECT OF CASEIN HYDROLYSATE, GLUTAMINE, ASPARAGINE, 2,4-D, AND ADENINE SULPHATE ON EMBRYOS GROWN IN VITRO

In the investigations of young embryos and other reproductive organs cultured in vitro, casein hydrolysate, glutamine, and asparagine have been used as supplementing growth substances. 2,4-D has been used to induce callus from rye embryos cultured in vitro. Adenine sulphate also has been used in embryo culture. The present report deals with the effects of casein hydrolysate, glutamine, asparagine, 2,4-D, and adenine sulphate on young Ginkgo embryos. In the dissection and disinfection of the material and the preparation and sterilization of basic medium the methods used this
