The intensity of colour in generative nucleus by using Feulgen reaction was deeper than vegetative nucleus and two sperms forming later. The generative cell and vegetative nucleus gave a positive reaction to PAS stain. 生殖细胞核孚尔根染色反应要比营养核以及后来形成的两个精核的染色深,生殖细胞与营养核PAS反应均为阳性。
The embryo initials and suspensor cells showed very weak Feulgen positive reaction in the proembryo and young embryo. 在原胚及幼胚胚原细胞质中也呈现很弱的正反应。
A reinvestigation on the characteristic of preserving the original position of DNA in Feulgen reaction with different methods of hydrolysis 从不同水解方法重论Feulgen反应定位DNA的特异性
The nuclear plasm of megaspore and 2 and 4 nucleate embryosac shows a positive Feulgen reaction. 大孢子母细胞及二、四核胚囊的核质显示Feulgen正反应。
Oocytes grew in size and entered into the neck region; nutritive cord appeared. DNA showed a positive Feulgen reaction. 第2阶段:卵母细胞位于颈区,开始增大,出现了营养索,DNA呈明显的孚尔根正反应。
And the Feulgen reaction was used for micronuclei analysis. 通过Feulgen反应染色组织切片以作微核分析。
The treatment with Feulgen reaction shows that the DNA of undergo the following change: The nuclei of microspore mother cells are of fresh purply red color and the protoplasms are colorless; 用孚尔根核染色反应处理DNA的变化:小孢子母细胞的核是鲜紫红色,细胞质无色;
In proembryo stage, the Feulgen reaction is positive. The nucleolus is Feulgen negative all the time. 到原胚期,Feulgen正反应恢复正常,核仁在全部过程中均为Feulgen负反应。
An Observation on the Features of Water-washed Basic Fuchsin with Special Reference to the Quality of Schiff's Reagent and the Colour of Feulgen Reaction 对水洗碱性品红的染料性状、Schiff试剂质量和Feulgen反应色调的观察
