[Study of surface properties of chloroplasts of some beans using a binary phase polymer system]

The surface properties of chloroplasts in leaves of some leguminous plants--Pisum sativum, Trifolium paratense, Melilotus album, and Vicia cracca--were investigated, based on the analysis of phase formation kinetics of the aqueous polymeric two-phase system dextrane-500/polyethyleneglycol-6000. The surface properties of chloroplasts have been shown to display both species- and sort-specificity. A specific influence of chloroplasts of melilot and non-chlorophyllic pea lines on phase formation kinetics has been noticed.
