摘要
为了弄清桃亚属中国分布植物的系统发育及演化关系,对这些种类的植物学性状以及核ITS序列和叶绿体psbA-trnH序列进行比对分析,植物学性状和ITS序列分析分别采用SPSS和MEGA构建系统树,psbA-trnH序列分析采用Network构建进化网络。结果表明:新疆桃确为普通桃的一个亚种;陕甘山桃不是山桃的变种,而是一个独立的种;桃亚属植物的演化关系为光核桃→甘肃桃,甘肃桃通过其中一支演化为山桃→陕甘山桃,另一支演化为普通桃和新疆桃。
To study the phylogeny and evolutionary path of subgenus Persica in China,the botanical characters,internal transcribed spacer（ITS）of the nuclear ribosomal DNA and psbA-trnH of the chloroplast DNA were used,and the three data were respectively analyzed by software SPSS 13.0,MEGA 3.0 and Network.Results indicated that A.ferganensis was a subspecies of A.persica,and suggested scientific name as A.persica ssp.ferganensis;A.potaninii was a independent species.The evolution sequences of subgenus Persica was：A.kansuensis evolved from the original species A.mira,then evolved through two route,one evolved to A.davidiana and then to A.potaninii,other evolved to A.persica and A.persica var.ferganensis.
