利用Giemsa C-分带和荧光原位杂交的方法对龟甲竹根尖细胞有丝分裂中期染色体进行了研究.结果表明:龟甲竹的核型公式为2n=48=26m+14sm+4st(2SAT)+4t,核型分类属ⅡB型;带型公式为2n=48=4CI+2CI+T+2CT++IOCT++4I+2I++6T++6C+8T+2IT+2I+T,每条染色体都显示出了可以明显区别的特征带,带纹强弱差异明显.以45S rDNA为探针对龟甲竹根尖染色体进行了荧光原位杂交,杂交位点定位于1对染色体上.将染色体c-带带型和45S rDNA FISH带型相结合可以将龟甲竹的每条染色体区分开. 相似文献

甘薯台龟甲与寄主植物之间关系研究结果表明,甘薯台龟甲嗜食旋花科植物.强迫取食试验发现,甘薯台龟甲能少量取食薇甘菊,但不能满足其生长发育;而在旋花科植物上取食力和繁殖力强,对旋花科杂草的生物防治有一定作用.选择性取食试验结果表明,在甘薯台龟甲的寄主范围内,任何世代的成虫和幼虫对供试寄主群中各种植物的选择性差异不明显. 相似文献
