【摘要】 <正> 本文继续对5属14种姜科植物作染色体计数观察,其中8种是染色体计数的新记录(表1,图版Ⅰ)。通过对偏穗姜(Plagiostachys austrosinensis T. L.Wu & Senjen)的根尖染色体观察,初步确定偏穗姜属(Plagiostachys)的染色体基数为12,并首次报道了阳荷(Zingiber striolatum Diels)的核型。更多还原

【Abstract】 This is the sixth paper on the chromosome numbers on Chinese Zingi-beraceae. Chromosome counts (2n, n) are reported for 14 species, belonging to 5 genera, of which 8 species are new records.Plagiostachys austrosinensis, is an octoploid with 2n=96. This suggests a basic chromosome number 12 for Plagiostachys the same as Alpinia and Amomum. The authors also describe for the first time karyotype of Zingiber striclatum Diels, which is an endermic species to China. Its karyotype formula is K(2n) = 22=20m + 2sm. The karyotype belongs to "1A" of Stebbins (1971).All the voucher speciments of the present study are preserved in the Herbarium of South China Institue of Botany, Academia Sinica.更多还原
