1问题李金安[湖北省武汉市新洲区城关高中(430400)]人教版高中《生物·选修1·生物技术实践》P.37:采用花药培养的方法,使花粉发育为单倍体植株,再经过人工诱导使染色体数目加倍,重新恢复到正常植株的染色体数目。P.40:在花药培养中,特别是通过愈伤组织形成的花粉植株,染色体组数目常常会发生变化。因此还需要对培养出来的植株作进一步的鉴定和筛选。不知道在月季的花药培养过程中,究竟通过哪种方法获得染色体加倍的植株?
1 problem Li Jinan [Wuhan City, Hubei Province Chengzhou high school (430400)] PEP High School “Biology · Elective 1 · Biotechnology Practice” P.37: The method of anther culture, the pollen developed into haploid plants, After artificial induction, the number of chromosomes is doubled and the number of chromosomes in the normal plants is restored. P.40: In anther culture, especially in pollen plants formed by callus, the number of chromosome sets often varies. Therefore, the cultivated plants need to be further identified and screened. Do not know in the rose anther culture process, what method to obtain chromosome doubling plants?
