Physiological aspects of steroids in pollen of Pinus elliotti Engelm /

Abstract

Biochemical Aspects of Sterols in Higher PlantsDimethyl sulphoxide (10 -4 M) increased the relative germination to 82%, further addition of pregnenolone, estradiol, estriol or corticosterone (each 10 -5 M) restored germination to almost optimum levels. Animal steroid hormones increased the conductance of the pollen media; however, there was no discernible relationship between increased germination and
