| Abstract: |
| In this paper,the chromosome numbers of 10 species of 3 genera in Zingiberaceae were reported. The results are as follows:(1)5 species of Zingiber:Z.xishuangbannaense 2n=22,Z.recurvatum 2n=22,Z.orbiculatum 2n=22,Z.zerumbet 2n=22,Z.purpureum 2n=22;(2)4 species of Globba:G.racemore 2n=24,G.marantina 2n=48,G.schomburgkii 2n=48,G.lancangensis 2n=32;(3)1 species of Boesenbergia:B.albomaculata 2n=36. The chromosome numbers of Z.recurvatum,Z.orbiculatum,Z.purpureum,G.lancangensis,B.albomaculata were reported for the first time. |
