Abstract
Neither the incubation of the flower scapes of garlic (Allium sativum L.) in tetracycline solution nor the extirpation of the bulblets from the inflorescences led to the development of fertile binuclear pollen. Higher tetracycline concentrations than 125 mg per litre showed a clearly phytotoxic effect. The removal of the bulblets from the inflorescences improved the survival of flowers but it enabled only the initial stages of seed development. The seeds obtained were defective and not able to germinate. The hypothesis on infectious nature of the factors causing sterility in garlic is discussed.
