Effects of Some Inorganic Nitrogenous Substances on Growth and Nitrogen Assimilation of Young Plant Embryos in Vitro

Abstract

Young excised embryos of Anagallis arvensis L. (Primulaceae) and of the cruciferous species Arabidopsis thaliana (L.) Heynh., Oapsella bursa.pastoris (L.) Moench., and Sisymbrium orientale L. were fed with inorganic and organic nitrogenous compounds whilst they were kept in "sitting drop" cultures for periods of 48 and 96 hr.
