Metabolism of excised embryos of Lupinus luteus L. VI. An electrophoretic analysis of some dehydrogenases in cultured embryos as compared with the normal seedling axes

J. Czosnowski


The electrophoretic patterns (disc electrophoresis) of the studied dehydrogenases: glucose-6-phosphate - (A), malate - (B), glutamate - (C), alcohol - (D) and lactate dehydrogenase (E), in the axial organs of isolated Lupinus luteus embryos and seedlings cultivated over 12 days are characterized by great similarities. With time, after the third day of cultivation the patterns begin to become less deyeloped. Analyses performed during the first 10 hours of imbibition of seed parts indicate that the maximal development of isozyme patterns occurs during the third hour after which the patterns become poorer. The most uniform type of pattern. and the lowest number of isozymes was shown by glutamate dehydrogenase, the richest pattern was shown by malate dehydrogenase. No band common for a 11 the 27 experimental elements was found.
