构成芝麻产量的农艺性状较多,如株高、腿高、分枝数、叶腋蒴数、全株蒴数、蒴粒数以及千粒重等,它们之间是相互联系又相互制约的。研究分析这些关系,对育种和栽培技术有一定的意义。1979年我们用河南省提供编写《中国芝麻品种志》的49个品种,进行产量构成因素相关性分析,其结果与1962、1963年的研究基本一致。相关性的分析研究,使我们对芝麻产量及其构成因素间的关系,有了进一步的了解。
There are many agronomic traits that make up sesame yield, such as plant height, leg height, number of branches, number of leaf axils, number of bolt per plant, number of bolls and grain weight, which are interrelated and mutual restraint. Studying and analyzing these relationships has some significance for breeding and cultivation techniques. In 1979, we used 49 varieties of “Chinese Sesame Breeds” prepared by Henan Province to analyze the correlation of yield components, and the results were basically consistent with those of 1962 and 1963. The analysis of the correlations has given us a better understanding of the relationship between sesame production and its components.
