New Hybrids from Incompatible Crosses in Datura Through Culture of Excised Embryos on Malt Media

Abstract
The technic of cultivating hybrid Datura embryos on artificial media was improved by use of the "embryo factor," the application of the method of van Overbeek and Conklin which allows Datura embryos to be excised and cultivated earlier, and by the use of malt extract as a more convenient source of the "embryo factor" than coconut milk.
