本文为漆树解剖学系统研究的第二篇报道,叙述根尖的结构、初生结构的分化以及次生结构的形成过程。材料及方法研究材料1981年采自陕西省平利县胜利公社。以漆树农家品种红皮高八尺为主,并以其它农家品种作对比。材料以FAA溶液固定,石蜡法制片,连续切片厚度为10微米,铁矾——苏木精染色,桔红G纯酒精溶液复染,并以番红——固绿双重染色对比。 This article is the second report of the study on the anatomical system of Rhus Andesite. It describes the structure of the apical root, the differentiation of the nascent structure and the formation of the secondary structure. MATERIALS AND METHODS Materials 1981 was collected from Shengli Commune, Pingli County, Shaanxi Province. To Rhus typhina Pei-breed high eight feet mainly, and other farm varieties for comparison. Materials FAA solution fixed, paraffin method of production, continuous section thickness of 10 microns, alum - hematoxylin, orange G pure alcohol solution stained, and the saffron - solid green double staining comparison.
