为了给漆树的品种分类、良种选育提供细胞学依据,我们自1981年起,对漆树花粉母细胞的减数分裂进行了观察,同时,对减数分裂的取材时机和染色方法进行了探索,现将结果报道于后。一、取材。材料采自本园引种栽培漆树(Rhus verniciflua Stokes)的4个品种:火焰子、大红袍、高八尺、贵州树。 (一)减数分裂的日期。在我园栽培条件下,5种材料的减数分裂均出现在5月1日 In order to classify the varieties of Acacia catenella and provide the basis for the breeding of the elite varieties, we observed the meiosis of S. japonicum pollen mother cells from 1981, and at the same time, we explored the sampling timing and staining methods of meiosis, The results are reported later. First, drawn. Materials collected from the garden introduction of cultivated Rhus verniciflua Stokes four varieties: Flame, Dahongpao, eight feet high, Guizhou tree. (A) the date of meiosis. In my garden cultivation conditions, the five kinds of material meiosis occurred in the May 1
