In this paper , we also study the change of peroxidase isozymes of the callus were treated by adding colchicines into the medium and the regenerated tetraploid plants . the results showed that callus and the plants had different regulated modes on peroxidase . compared with the control , the band number and activity of peroxidase isozymes of callus treated with colchicines were raised obviously , and two new enzyme bands appeared , while the regenerated tetraploid plants only showed the activity raising 与对照相比，秋水仙碱处理后的辣椒愈伤组织的过氧化物酶同功酶的活性和酶带数目都发生了变化，过氧化物酶活性有所提高，并观察到新的酶带产生；而分化的四倍体植株的过氧化物酶同功酶只有表达量的提高，未见新的酶带产生。
Distribution zone of diploid individual are the most extensive in china , while no tetraploid plant is found north of 40 degree north latitude , and hexaploid populations distribute mainly along the changj iang river , is found only in three populations in the yunnan - guzhou plateau . the hexaploid cytotype of var 4细胞地理学研究表明，二倍体占据我国最广大区域，而四倍体分布区的北界则向南迁至40 n ，六倍体主要分布于25 n - 33 n的狭长地带，八倍体则在云贵高原中部及东部边缘零星分布。
