Ⅰ绪言据报导,花生(Arachis)在细胞学上的困难是所得结果往往染色体染色不良并且分散不好,因而不易区分。其染色体小,在有丝分裂中期仅为1.8—3微米。这是这个属在细胞遗传学方面缺乏报导资料的原因之一,虽然它包括着主要油料作物之一的花生.我们曾经常研究细胞学技术并且得到染色体着色适度而又与细胞质背景成明显反差的标木。本文的目的在于概述我们的技术,这一方法对于其他在细胞学上有困难的植物也同样是有效的。
I. INTRODUCTION It has been reported that the cytological difficulty of Arachis is that the results obtained tend to be poorly stained and poorly dispersed and therefore indistinguishable. Its chromosomes are small, only 1.8-3 microns in the metaphase. This is one of the reasons why this is a lack of information on cytogenetics, although it includes peanuts, one of the major oilseed crops, and we have often studied cytology and got a modest chromosomally colored contrast to the cytoplasmic background Standard wood. The purpose of this article is to outline our technology, which is equally valid for other cytologically difficult plants.
