Abstract

Field studies of seasonal sprouting of wild garlic (Allium vineale L.) bulbs showed that all the soft offset, aerial, and central bulbs sprouted, but only 20 to 34% of the hardshell bulbs sprouted after a short after-ripening period. Each fall, a percentage of the remaining hardshell bulbs sprouted, but after 4 years 16% of the hardshell bulbs were still dormant. Embryonic shoots of all bulb types sprouted when excised following the after-ripening period. In addition to a short after-ripening period, hardshell bulbs had a prolonged dormancy due to some mechanism which resides in, or was controlled by, the tissue surrounding the embryonic shoot.
