Abstract
Th e histochemical analysis of the mature ovule was performed in the species of Trollius asiaticus L. and T. ledebourii
Reichenb. Distribution of carbohydrates and RNA/DNA ratio were studied. It was found that halazal nucellus area
had a complex organization, and formed an atypical podium consisting of morphologically different cells.
Histochemical diff erences in them are minimal.
