Bert John Neubert,Wolf-Dieter Scharfege when nuclear DNA is not replicating. In embryos of rye and wild oat, the tolerance is lost at the onset of S-phase coincident with radicle extension but in birch pollen tolerance is lost on pollen tube extension in the absence of DNA replication. The current experiments were aimed to determine wh

These studies disclosed that metabolically active and quiescent tissues can be distinguished by their biotin content. In young developing seeds, as well as in germinating seeds, there is an excess of free versus bound

High Power Laser-Matter Interactionsorption and diffusion properties of different coatings were investigated. By increasing alginate and CaCl. concentrations, and by adding mineral elements to alginate, the resistance of the matrix to rupture was increased, but the germination of somatic embryos was depressed. Alginate-kaolin or algi
