Abstract
Esterases, leucine aminopeptidases, catalases and acid phosphatases from pollen of Oenothera organensis were studied electrophoretically. A study was made using several different extraction media to see the effect it had on esterase migration and stainability. It was found that different extraction media resulted in significant changes in migration rates and stainabilities of the esterase isozymes.Anodal esterases and leucine aminopeptidases from 13 inbred lines of maize were studied and are reported. Preliminary genetic studies of two of the esterase isozymes from maize pollen are reported.A survey of anodal esterases and leucine aminopeptidases from the pollen of 11 genera of diverse angiosperms is presented.
