 note = {1. Asimina triloba DUNALの染色体は, n=8,2n=16と決定された。染色体は5型(a-e)に分類され, 各染色体の長い腕上には, 1個の狭窄が存在し, a型上にのみ, 2個の狭窄が見られる。b型には, 1個の附随体が存在する。2. 実生の腋芽に対するコルヒチン滴下処理により, 4倍体(2n=32)及び8倍(2n=64)体夫々1個が得られた。この2個体は, ミクソプロイドである事が認められた。2倍体, 4倍体及び8倍体個体の気孔の大きさは, 互に, 有意な差異を示し, 漸次, 8倍体に向つて, 巨大性を示してゐる。, 1. The chromosome numbers of Asimina triloba were determined as n=8,2n=16. The chromosome complement was classified into 5 types. The long arms of each type have a constriction and that of a type has two constrictions. The chromosomes of b type have a satellite. 2. By the colchicine treatment autotetraploid (2n=32) and auto-octaploid (2n=64) plants were obtained. These plants were shown to be mixoploids; in the leaf of tetraploid plant diploid numbered cells were found, and similarly, in the octaploid plant tetraploid numbered cells were found. The size of the stomata in the diploid, tetraploid and octaploid plants show significant differences from each other.},
