有丝分裂是植物细胞增殖的最普遍分裂方式,对植物个体的生长和繁衍极为重要。植物育种工作中,观察染色体形态,染色体结构变异及确定染色体数,必须在有丝分裂过程中寻求,而对樟子松有丝分裂规律的研究,迄今报导甚少。本实验通过樟子松有丝分裂的大量观察,系统了解有丝分裂过程,寻求木本植物细胞分裂的旺盛时期,尤其是中期分裂相,对指导木
Mitosis is the most common mode of division of plant cell proliferation and is extremely important for the growth and reproduction of individual plants. Plant breeding, observation of chromosome morphology, chromosomal structure variation and the number of chromosomes must be sought in the process of mitosis, while the study on the mitosis of Pinus sylvestris var. Mongolica has reported little. In this experiment, through extensive observation of mitosis of Pinus sylvestris var. Mongolica, the process of mitosis was systematically studied to find out the exuberant period of cell division of woody plants, especially the metaphase,
