摘    要:采用常规根尖压片法对甜玉米和糯玉米的染色体标本做核型分析.结果表明: 甜玉米(L-11株系)和糯玉米(L-70株系)的染色体数均为2n=20,两者均为二倍体.甜玉米核型公式为2n=2x=20=2M﹢12m﹢6sm(2Sat),染色体相对长度系数组成为2L﹢4M2﹢12M1﹢2S,按照Stebbins标准核型分类属于2B核型,不对称系数AS.K%=59.66%.糯玉米核型公式为2n=2x=20=2M﹢8m(2Sat)﹢10sm,染色体相对长度系数组成为2L﹢8M2﹢6M1﹢4S,分类属于2A核型,不对称系数AS.K%=60.41%.说明甜玉米(L-11株系)的进化程度较高.

关 键 词:核型不对称系数

Abstract:A compound which shows a significant aggregation-induced emission (AIE) phenomenon was used to make polymer by electrochemical polymerization. The structures, optical performance and surface morphology of the electrochemical polymerization (EP) films were characterized by means of infrared spectroscopy (FTIR), near ultra violet(UV), photoluminescence (PL) measurements and atomic force microscopy(AFM). The result showed that the electrochemical polymerization proceed from the 3 and 6 positions of carbazole groups, the film emitted blue fluorescence and had flat surface which the root mean square (rms) of surface roughnesses was 3nm below. It is suggested that they are potential materials for fabrication in PLED devices.
Keywords:sweet corn  waxy corn  Karyotype analysis  Asymmetrical karyotype coefficient
