在被子植物中,木本植物的染色体一般较小,数目多,因而制片难度大,观察也较困难。漆树的细胞不易染色,同时,其种子不易萌发,发芽率低,造成根尖制片取材不易,所以漆树染色体的观察有较多的困难。我们用早春叶芽为材料进行漆树体细胞染色体观察,得到了较满意的结果。现将实验结果总结如下: In angiosperms, woody chromosomes are generally small and numerous, making it difficult to produce and difficult to observe. The lacquer tree cells are not easy to stain, at the same time, the seeds are not easy to germinate, the germination rate is low, resulting in apical filming is not easy, so the observation of Chromosome chromosomes have more difficulties. We use the early spring buds as the material for Solanum cell chromosome observation, obtained more satisfactory results. Now the experimental results are summarized as follows:
