【摘要】 本文报道了磨芋属(Amorphophallus Blume)六个种的染色体数目和核型,其中5个种属于首次报道。其核型公式如下: 1.滇磨芋 K(2n)=2x=26=26m.2.磨芋 K(2n)=2x=26=26m.3.攸落磨芋K(2n)=2x=26=22m(2SAT)+4sm.(2SAT).4.西盟磨芋 K(2n)=2x=26=20m+4sm+2st.5.勐海磨芋 K(2n)=2x=26=22m+4sm.6.白磨芋 K(2n)=2x=26=20m(2SAT)+6sm。更多还原

【Abstract】 Chromosome numbers and karyotypes are reported for 6 species of Amorp-hophallus (Araceae). Of these, 5 species are recorded for the first time. The karotypes can be formulated as follows:1. Amorphophallus yunnanensis K(2n)=2x=26=26m: 2.A. konjac K(2n)=2x=26=26m; 3. A. yuloensis K(2n)=2x=26=22m(2SAT)+4sm(2SAT); 4. A. ximengensis K(2n)= 2x=26=20m+4sm+2st; 5. A. bannaensis K(2n)=2x=26=22m+4sm; 6. A. albus K(2n) =2x=26=20m(2SAT)+6sm.更多还原
