Abstract: The experiment tried to treat garlic bulbs with different concentrations of GA₃,ETH and low temperature,in order to find out the technology and physiological characteristics of rapid release of garlic dormancy,shorten the production time of garlic without affecting the quality of garlic.The test variety was Jinxiang garlic,the dormant garlic bulb was a bulb stored at ambient temperature for 2 weeks,and the germination garlic was taken from the bulb stored at ambient temperature for 16 weeks.16 different concentrations of gibberellin and ethephon in hormone solution soaked dorment garlic for 1 hour,after soaking out,each treatment with 4,8,12,16℃ low-temperature treatment for 4,8,12,16,20 days,to compare the germination rate of different treatments and the indexes of garlic seedling height,stem coarse and bulb nutrition quality.The consequence indicated that,the germination rate of GA₃,ETH concentration of 50 mg/L and 150 μL/L in different treatments was higher than that of other treatments,the germination rate of 12℃ low temperature treatment garlic bulb was generally faster than other temperature treatment,and garlic bulbs that were treated with low temperature for 20 days break dormancy fastest.Combining all the results to conclude that garlic bulbs immersed in GA₃, ETH concentration of 50 mg/L,150 μL/L solution,and then 12℃ low-temperature treated for 20 days could effectively break the garlic dormancy,the dormant period of garlic bulbs shortened more than 40 days,the germination rate of garlic was the fastest and there was no adverse effects on the quality of garlic growth.Using this method in production could make garlic sow in advance,and improved farmers' economic benefits.
