Abstract: The growth characteristics of garlic bulb and main agronomic traits were revealed by observing the agronomic traits of garlic at different developmental stages.The white garlic T261,T36-1 and the purple garlic ZhongsuanNo.1,Tuodusuan,T17 were used as materials. From the bulb swelling initial period to the maturation stage,the plant height,plant width,leaf length,leaf width,leaf number,root hair length,bulb diameter,bulb height,fresh bulb weight,aboveground part weight,bulb weight,dry weight of aboveground and bulb part and dry weight of root hair of five varieties were measured by 15 plants randomly selected from three replicates in each seventh day from 20th March to 15th May,2015. The bulb diameter,bulb height and dry weight of underground of all the varieties increased throughout. However,the dry weight of root hair and aboveground part weight increased in the earlier stage and decreased in later. ZhongsuanNo.1 was superior to other varieties in most phenotypic traits. After 8th May,the dry weight of underground part of T261,T17 and T36-1 had a little decline,while Tuodusuan and ZhongsuanNo.1 increased,that means maturation time was different among varieties,and different optimum harvest dates should be set to the different varieties to obtain the highest bulb yield. ZhongsuanNo.1 and Tuodusuan belong to the late-maturing garlic,while T17,T261 and T36-1 belong to the early-maturing garlic.The increased of the bulb diameter of ZhongsuanNo.1,Tuodusuan garlic and T17 was faster than that of white garlic T261,T36-1. Besides,the bulb dry weight of purple garlic was also significantly higher than that of white garlic close to maturation,and the value of dry matter utilization was higher.The dry weight of aboveground was positively related with the dry weight of bulb in the earlier stage and decreased later.By the observation of multiple traits of garlic varieties,and according to the change of dry weight,fresh weight of garlic bulb,the key point period of garlic growth was found. The study will benefit the breeding and production of garlic.
