抄録

Optimal carbamate treatment conditions were studied for flower induction in seedlings of an asparagus cultivar 'Mary Washington 500 W'. Flower induction was most accelerated by soaking seeds in 50 mg l-1 carbamate solution for 12 days at 25 °C under the fluorescent light. Longer exposure to carbamate over a 12 day period induced a higher percentage of seedlings to flower. A higher percentage of flowering seedlings were male. Flower induction frequency among seven cultivars through carbamate treatment widely ranged from 13 to 67%. 'Geynlim', 'Mary Washington 500 W' and 'Welcome' exhibited a high percentage of flowering seedlings, while 'Larac' and 'Vulkan' showed low values. Only male flowers were induced in all-male cultivars. Variation in pollen germination was found within all cultivars. 'Geynlim', 'Cito' and 'Mary Washington 500 W' showed high values of average pollen germination. Application of carbamate compound to induce flower production can rapidly produce homogenic cultivars which include both sexes. This is necessary for genetic studies and breeding purposes.
