摘    要:以大蒜根尖为试验材料,用常规压片法制备染色体标本,研究取材时间和预处理方法对大蒜有丝分裂指数的影响.结果表明低温处理组上午9:40-10:00、8-羟基喹啉处理组上午9:00-9:20、对照组10点左右取材有丝分裂指数最高,且低温预处理效果明显好于8-羟基喹啉和对照组.

关 键 词:大蒜  有丝分裂指数  取材时间  预处理

Abstract:The chromosome specimens of garlic root-tip were made with traditional squashing method.The effects of different time for taking root and pretreatment methods on Garlic mitotic index were studied.The results showed that: The highest mitotic index is at 9:40-10:00(a.m)with low-temperature pretreatment,9:00-9:20(a.m)with 8-hydroxyquinoline pretreatment and about 10(a.m)without pretreatment.And low temperature pretreatment effect was significantly better than 8-hydroxyquinoline and controls.
Keywords:Garlic  mitotic index  time of fetching material  pretreatment
