Synthesis of DNA and the Development of Amylase and Phosphatase Activities in Cotyledons of Germinating Seeds of Vaccaria pyramidata

Authors:	BERNHARDT D; TRUTWIG A; BARKHOLD A

Abstract:	As in cotyledons of Agrostemma githago, synthesis of DNA takesplace after germination in cotyledons of Vaccaria pyramidataand is followed by the formation of hydrolases, in particular, ${alpha}$ -amylase and acid phosphatase. If DNA synthesis is inhibitedby hydroxyurea, no, or only slight, enzyme activity develops.The possible role of this DNA synthesis is discussed. Key words: DNA synthesis, amylase activity, phosphatase activity, seed germination, cotyledons, Vaccaria pyramidata
