Claim:
1. A method of dispersion of clusters of plant propagules suspended in a liquid into individual plant propagules flowing through a flow channel, the method comprising: a. feeding clusters of plant propagules into a disperser for separating individual plant propagules contained in the clusters of propagules; b. subjecting the clusters of plant propagules to axially extensional strain and radially compressional strain; c. subjecting the clusters of plant propagules to fluid dynamics forces causing axially compressional strain and radially extensional strain from fluid dynamics forces; and d. repeating the subjecting steps in sequence until the individual plant propagules are separated from each other, wherein the disperser comprises a flow channel including at least two constrictions, wherein each constriction of the at least two constrictions has an inner diameter that is equal to or smaller than the inner diameter of the constriction immediately up-stream thereof, wherein each constriction of the at least two constrictions has a cross-sectional area in the interval from 0.75 to 1300 mm wherein the flow channel includes an intermediate portion between sequential constrictions, wherein the longitudinal axes of said at least two constrictions align with each other.
