核酸及核朊物質在生物有机体的代谢、分化、发育和适应上都起着重要的作用。在植物发育阶段的变化上核酸物質含量的探讨,也是很有兴趣的问题。所以在1953—1954年,便进行了春化过程中小麦胚中核酸含量的测定。以了解在春化阶段核酸物变化的情况。现在将实验方法及结果简单介绍於下。一.实验方法实验材料是采用冬小麦“小红芒”及“北系3号”两品种。种子经过消毒後,分别补足水分 Nucleic acids and nuclear proteins play an important role in the metabolism, differentiation, development and adaptation of biological organisms. Discussion of changes in plant development on the content of nucleic acids is also of great interest. Therefore, in 1953-1954, the determination of nucleic acid content in wheat embryos during vernalization was carried out. In order to understand the changes of nucleic acid in the vernalization stage. Now the experimental methods and results are briefly introduced below. Experimental methods Experimental materials are the use of winter wheat “Little Hongmang” and “North Line 3” two varieties. Seeds were sterilized, respectively, make up the water
