Conteúdo: | Three techniques of the test-tube fertilization by means of an artificial pollen tube culture are described. The essentials for each individual method are: 1. Transfer of pollen tubes from the sugar solution onto the placentae in the test tube. Placing the placentae with ovulesonto pollen tube culture. Precultivation of pollen tubes on small cellophane squares placed on the surface of a semiliquid medium and transfer of cellophane squares along with the pollen culture to the solid medium, over which finally the placentae with ovules are placed. By means of all the three techniques viable seeds were obtained in vitro. In an artificial medium pollen tubes are able to maintain their fertilizing ability even after the 24 hour cultivation, i.e. at the time after the formation of the gametes.
