In vitro placental self and cross pollination in some species

Abstract

Excised placentae with ovules of Primula pubescens, P. auricula, Scopolia carniolica, Digitalis purpurea, Torenia fournieri and Chionodoxa luciliae were self pollinated in vitro and the development of seeds was observed. The same method was used for obtaining hybrid globular embryos from crosses between: P. pubescens x P. auricula, Scopolia carniolica x Physochlaina praealta, Melandrium album x Silene saxifraga and M. album x Arenaria pungens.
