在研究PICCH(丙酸—铁—洋红—水合三氯乙醛)染色剂在蔬菜作物染色体的染色技术上已经取得了良好的效果。丙酸不仅是一种良好的固定液,而且在配制洋红染液时,用丙酸作溶剂,可以溶解较多的洋红和铁,对于媒染和染色都非常有利,再加上水合三氯乙醛起透明的作用,所以在经过对蔬菜作物小染色体染色试验后,效果非常明显。但其染色效应在其它作物和果树上如何,我们于1979—1980两年中分别用小麦、水稻、玉米和果树的枣、杏为材料进行了探讨性的试验,也取得了良好的效果。一、试验材料和方法果树的染色体很小,而且难于染色。我们采用了我校标本园的麦黄杏品种作为
In the study PICCH (propionic acid - iron - magenta - chloral hydrate) stains in the vegetable crop chromosome staining technology has achieved good results. Propionic acid is not only a good fixative, but also used as a solvent in the preparation of magenta dye, which can dissolve more magenta and iron, which are very beneficial for mordanting and dyeing. Coupled with hydrated trichloroacetaldehyde Play a transparent role, so after a small chromosome staining of vegetable crops, the effect is very obvious. However, the dyeing effect on other crops and fruit trees, we in 1979-1980 respectively, wheat, rice, corn and fruit jujube, apricot as a material of the exploratory test, but also achieved good results. First, the test materials and methods Fruit trees chromosomes are small, and difficult to stain. We use the sample of our school apricot variety as apricot
