XIAO Gui-zhi,FENG Yong-ping,Hou Jin (Chengde Medical College,Hebei Chengde,067000 China)  
Objective:To investigate the optimum condition of Allium sativum L.of the high mitotic index of root-tip.]Methods:Resumptive cultivating method and unresumptive cultvating methods were used.Fetch materials by the length of the same root-tip,at different time and the same time from the different lenth roots.Results:The root length of unresumptive cultivation group is 2cm~4cm and the lenth of the other is 2cm~5cm.The highest mitotic index is at 8 oclock(a.m) and 2 oclock(p.m).Conclusion:Allium sativum L. mitotic index corralats with the root-tip length and the time of fetching material.
