| 摘要: |
| 贮藏期间蒜种呼吸增强,乙烯含量降低,低温贮藏促进这些变化;随空气湿度增大,蒜种呼吸及含水量有增加趋势。鳞茎形成过程中鳞茎中游离氨基酸减少,蔗糖和果糖增加,低温贮藏蒜种加快了这一进程。贮藏温度效应大于湿度效应,低温(5℃)和高湿(75％或100％RH)贮藏蒜种对初级生长及二次生长促进最显著。贮藏温度越低,外层型二次生长(SGo)越严重;内层型二次生长(SGi)与蒜种贮藏温度呈‘V’型曲线关系。低温下,高湿贮藏蒜种较低湿(25％或50％RH)贮藏蒜种SGo及SGi均极显著增加。 |

| Abstract: |
| The respiration of seed cloves was strengthened but the ethylene contents in seed cloves was decreased during the storage．Low temperature storage can encourage these changes．There was an increasing trend in respiration and water contents of seed cloves with an increase in humidity．Free amino acid was decreased but sugar and fructose were increased in bulbs daring the bulb formation,and low temperature storage can intensify the progress．The efects of storage temperature were greater than those of storge humidity．seed clove storage by low temperatnre(5℃)and high humidity(75％ or 100％ RH)can greatly encourage the primary and secondary growths of garlic.The lower the storage temperature was,the m ore serious the secondary growth of out-layer type (SGo) was．The relation between the secondary growth of inner-layer type(SGi)and seed clove storage temperature appeard to be a V-shaped curve．Under low temperature storage condition，seed cloves stored at higher humidity most significantly increased both SGo and SGi than that stored at low humidity(25％ or 50％ RH)． |
