- 摘要:
- 为寻找冬凌草染色体观察的最佳染色制片方法,并确定冬凌草染色体数目,采用丙酸-铁矾苏木精染色方法,对冬凌草的根尖及下胚轴进行染色制片,通过比较不同浓度的预处理液、不同取材时间对制片效果的影响,以探寻适宜于冬凌草染色体制片的有效技术。结果表明:进行冬凌草染色体数目观察适宜选取的材料为下胚轴,且取材时间8:00-9:00为最佳,将下胚轴用0.1%秋水仙碱溶液处理1 h,并用丙酸—铁矾苏木精染色方法制片,观察到冬凌草染色体数目为16条。
- Abstract:
- In order to find the best staining method for the observation of chromosome,and to determine the number of the chromosomes of Isodon rubescens(Hemsl.)H.Hara,the root tip and hypocotyl of I.rubescens were dyed and prepared by propionic acid-iron sorghum hematoxylin staining method.By comparing the effects of different concentrations of pretreatment liquid and different materials on the effect of tableting to explored an effective technique for chromosome production of I.rubescens.The results showed that,to observe the snumber of chromosomes of I.rubescens,the experimental Materials were hypocotyls and the time was 8:00-9:00.The hypocotyls were treated with 0.1% colchicine solution for 1 h and prepared by propionic acid-iron sulphate hematoxylin staining method,and the number of chromosomes in I.rubescens was 16.
