Impova amakhiwane - kuba indaba ethakazelisa kakhulu ukuze ube nesifundo ehlukile. Iqiniso lokuthi izimbali komkhiwane zithola impova kuphela iminyovu blastofagi. iminyovu Wingless besilisa elinde insikazi ngaphakathi imbali wesilisa. I elivundisiwe zesifazane-blastofaga iqoqa impova eningi emzimbeni wesilisa yayo imbali, ukuphuma kulo, futhi ngifuna inflorescences entsha besilisa baphathe impova ezimbalini zesifazane.

amaqiniso ezithakazelisayo
