【摘要】 本文报道了我国4个地理品系卤虫的染色体倍性组成及卵径分布,分析了卤虫染色体的非整倍性,讨论了卤虫种的分布。 天津卤虫有2倍体(2n=42),占33.3％和5倍体,占16.2％;染色体数的波动为21—108;卵径为262±17μm。 海南卤虫有2倍体(2n=42),占8％;4倍体,占17.7％;5倍体,占18.3％;染色体数的波动为16—111;卵径为285±15μm。 新疆卤虫有2倍体(2n=42),占39.2％;染色体数的波动为17—106;卵径为269±15μm。 山西卤虫有2倍体(2n=42),占45.1％,染色体数的波动为17—84;卵径为234±13μm。更多还原

【Abstract】 This paper reports the chromosomal ploidy composition and cyst diameter distribution of 4 Chinese Anemia populations (from Tanggu salterns, Tianjin; Yinggehai salterns, Hainan; Aibihu Lake, Xinjiang and Yuncheng Salt Lake, Shanxi). The possibility of aneuploid in Ar-temia populations and the geographical distribution of Anemia species are discussed.Anemia from the population of Tianjin includes 33.3% of diploid (2n = 42) and 16.2% of pentaploid (5n = 105), the chromosome number fluctuating from 21-108; the cyst diameter is 262±17μm. Anemia from the population of Hainan consists of 8% of diploid (2n = 42), 17.7% of tetraploid (4n = 84) and 18.3% of pentaploid (5n = 105); the chromosome number (?)arying from 16-111; the cyst diameter is 285±15μm. Anemia from the population of Xinjiang includes 39.2% of diploid (2n = 42), the chromosome number fluctuating from 17-106; the cyst diameter is 269±15μm. Anemia from the population of Shanxi includes 45.1% of diploid (2n = 42), the chromosome number fluctuating from 17-84; the cyst diameter is 234±13μm更多还原
