From Germ Cells to Apples That the potentialities of numberless new va-rieties lie hidden in the pollen grains and ovulesof a single flower-cluster is a thought that makesstrange appeal to the imagination of the intelli-gent plant developer. When he pollenizes a flower he is bringing to-gether two germinal microcosms each of which,rightly viewed, is a universe within itself. He is dealing with individual life histories and^^dth the histories of races. [186]. C >» r, O -M ~ >(^ LUTHER BURBANK He is performing, as I said before, the mostmarvelous of all experiments. He deals with the same matter with which thechemist deals in his laboratory; but with this mat-ter aggregated into new and wonderful combina-tions which alone make possible those responsesto the environment and that primeval capacity forgrowth and of self-reproduction that differentiateswhat we call living tissue from the matter out ofwhicli it is constructed.
