摘要: 应用5对叶绿体DNA(cpDNA)特异引物对柿及其近缘的8个种共32个基因型的cpDNA进行PCR扩增。采用7种限制性内切酶对其扩增产物酶切位点变异分析表明,在供试柿属植物中存在丰富的种间多态性,但供试22个柿种内基因型未检测到变异位点。应用NTSYS中UPGMA法聚类和主坐标分析表明:柿与金枣柿最近缘,其次分别是油柿、云南野毛柿、浙江柿和君迁子,而与美洲柿和乌柿相距较远。野柿(浙江)为柿的变种,聚类结果也表明野柿(浙江)与柿有一定差异。

Abstract: Five special primer pairs of chloroplast genome were used to amplified chloroplast DNA (cpDNA)regions in 8 Diospyros species including 32 genotypes. The products were digested by seven restriction enzymes. The results showed high interspecific cpDNA variations within the genus Diospyros. Twenty-two D. kaki genotypes were detected no visually variation in this study. D. kaki had closely relationship with‘Jinzaoshi’,followed by D. oleifera,D. artrotricha,D. lotus and D. glaucifolia,but distant from D. virginiana and D. cathayensis in diagram based on the UPGMA cluster analysis by NTSYSpc 2.10e program. Wild persimmon(Zhejiang)is a variety varietas of persimmon. The result showed that wild persimmon(Zhejiang)is not closely similar to D. kaki.

Key words: Diospyros kaki, cpDNA, PCR-RFLP, genetic diversity, genetic relationship
