Abstract

A method is described for the rapid extraction of all alcohol soluble growth hormone from ground plant tissues, using absolute ethanol. The method does not involve use of ether or chloroform, and extracts can be prepared quickly for testing by standard procedures, such as Skoog's "deseeded" method or the "standard" method of Went. To date exhaustive tests have been made only on maize endosperms and entire maize seeds.
