The electrostatic interactions of the cationic dyes Pyronin B (PyB) and Pyronin Y (PyY) with the negatively charged colloidal silica was investigated by molecular absorption and steady state fluorescence spectroscopy. Both dyes indicated changes in the absorption and emission spectra upon interactio

The recombination frequency was measured between two linked marker loci a (anthocyaninless) and hl (hairless) in control and irradiated developing buds in Cluster I on the main stem in tomato. The buds which corresponded to early prophase I of meiosis showed significant increase in recombination fre
The spectrophotometric characteristics of analytically pure pyronin Y have been investigated. Addition of metal ions (Fe3+, Zn2+, and Mg2+) and of dextrin were shown not to influence the absorption characteristics. The composition of the solvent strongly influenced the value of the extinction coeffi
