Karyotype analysis for pollen mother cells meiosis diakinesis of Apium graveolens L.
摘要
Abstract
Using flower buds, karyotype analysis of Apium graveolens L during meiosis diakinesis in pollen mother cells was conducted,compared with chromosome karyotypc of root tip,and the best way to obtain diakinesis chromosomes was discussed. The results were the same: karyotype formula of Apium graveolens L. was K (2n) = 2x = 22 = 6m+2sm+8st+6t, both of which had 3 pairs of metacentric chromosomes (5,7,9), 1 pair of submetacentric chromosomes(6) ,4 pairs of with acrocentric chromosomes (2,3,8, 11 ) and 3 pairs of telocentric chromosomes(1,4,10). Relative length was 2n = 2S+2M 1 +6 M2 + 1 L, belonging to 3 B type.关键词
