用正红花油(Red Flower Oil,RFO)去壁,Giemsa染色法对黄果西番莲(Passifloraedulisvar.flauicarpa Degener)的染色体进行了G-显带研究和G-带带型分析.结果表明,全部9对染色体(2n=18)均显示出清晰的丰富的G-带带纹,但各条染色体的带纹数目随着有丝分裂时期的推进而逐渐减少,前期带纹数量多,早中期次之,中期最少或无带;各对同源染色体的两个成员之间带纹的位置、数目、大小、着色深浅和带间宽窄,彼此基本相似,可较准确配对,而非同源染色体之间的带型特征则各不相同,可一一区分.还对正红花油的作用机理和黄果西番莲染色体G-显带技术作了初步探讨.
The wall of Passiflora edulisvar. Flauicarpa Degener was analyzed by Giemsa staining and G-banding with Red Flower Oil (RFO). The results showed that all 9 pairs of chromosomes (2n = 18) showed a clear and abundant G-banding pattern. However, the number of bands of each chromosome decreased with the progress of mitosis and the number of pre-banding bands was earlier Medium-term, medium-term at least or without band; each pair of homologous chromosomes between the two members of the banded position, number, size, color depth and band width, similar to each other, can be more accurately paired, rather than homologous Chromosomes between the band characteristics are different, one by one distinction. The mechanism of action of safflower oil and the G-banding technique of passion fruit passiflora were also discussed.
