台灣芭蕉倍數性的研究
Study on Ploidy of Musa formosana (Warb.) Hayata in Taiwan
摘要
本研究證實台灣芭蕉[Musa formosana (Warb.) Hayata]的染色體數為2n=22，綜合先前形態特性調查資料，將台灣芭蕉歸類為Eumusa宗的二倍體野生種香蕉植物。以流式細胞儀測得台灣芭蕉體細胞核內DNA含量為1.387 pg/2C，基因組大小約為669.23 Mbp/2C，相較於尖蕉(M. acuminata)的A基因組與拔蕉(M. balbisiana)的B基因組大小，分別高出18%與26%。基因組大小的資料不僅可應用於不同物種的鑑定，尚可預測基因組間植株雜交後裔的基因組組成，而應用於雜交後裔的早期檢定。
並列摘要
The chromosome number and genome size of Musa formosana (Warb.) Hayata were analyzed. M. formosana had a diploid number of 2n=22 and is placed in section Eumusa to conform to the previous morphological studies. Nuclear DNA content or genome size of M. formosana was estimated to be 1.387 pg or 669.23 Mbp per 2C, which was larger than that of A and B genome by 18% and 26%, respectively. The difference in genome size estimated by flow cytometry can discriminate different genomes, which is reliable to identify species and to predict the genome constitution of their hybrids.
