中文摘要 | 1. 本試驗以G. javanica及G.tomentosa 等三個系統為材料,以Farmer's Solution固定,用Smear method 鏡檢,自1965年7月至1966年2月,在中興大學實施。 2. G. javanica 之染色體數有n=11及n=22 兩型,花粉母細胞分裂過程無異常現象,染色體形狀為小圓粒狀,Diakinesis時期配對良好,雙價染色體由二個單價染色體中間連有細絲構成。 3. 染色體n=11之G. javanica 其在Diakinesis時期,有三價染色體出現。 4. G.tomentosa 之染色體數n=22,花粉母細胞分裂正常,Diakinesis之配對方式和G. javanica大致相同,在Metaphase 時期染色體形成短桿狀,其他時期成小圓粒狀,但較G. javanica小且圓。 5. G.tomentosa在Diakinesis時期有一價及四價染色體出現。 |
英文摘要 | 1. Three strains from G. javanica and G.tomentosa were used as the materials. They were fixed with Farmer's solution and test with Smear method. The study was carried out from July, 1965 to February, 1966 in Chung-Hsing University. 2. There are two types of chromosome number N=11 and N=22 in G. javanica. In the process of pollen mother cell division, it showed without abnormal phenomenon. Chromosomes are small and round grain in shape, pairing normal at diakinesis, bivalent chromosomes were formed by two univalent chromosomes which connected with a thin thread. 3. Trivalents were observed at the diakinesis in meiosis of the G. javanica possessing N=11 chromosomes. 4. G.tomentosa possessed N=20 chromosomes. It's pollen mother cell division showed in normal. At diakinesis, chromosomes pairing are similar to G. javanica. At metaphase, chromosomes were formed in short rod shape, but showed smaller and more round grain than the G. javanica in chromosomes' shape at other stages. 5. Univalents and quadrivalents were observed at the diakinesis of G.tomentosa L. |
