典型品种花生种子尺寸及均齐性研究

选择辽宁省主栽的6种典型花生为研究对象,对种子尺寸和均齐性进行分析。使用统计学方法,以种子的三轴尺寸、平均径、百粒重为指标,分析种子三轴尺寸的统计分布特性、均齐性以及种子尺寸与百粒重的关系。结果表明,不同品种花生种子的三轴尺寸总体上存在显著性差异,但均服从正态分布;花生种子的三轴尺寸间存在线性相关;不同品种花生种子的均齐性存在差异;花生种子的几何平均径、算数平均径与百粒重的变化趋势相似。研究结果表明,不同品种花生种子的尺寸及均齐性存在差异。因此,应综合考虑多种因素对种子进行清选分级。

Size and uniform performance of seeds of typical peanut varieties

The sizes and the uniform performances of peanut seeds are the basis of seed cleaning and grading,and the core element of breeding peanut.Three axis dimensions,the average diameter and weight per 100 seeds were selected as indicators.The differences,distribution and interrelation of the three axis dimensions of the seeds,the uniform performance and the relationship between seed sizes and the weights were analyzed with statistics.The results showed that three axis dimensions obeyed the normal distribution with significant differences among different varieties of peanuts.There were linear correlations between three axis dimensions.Differences between seeds of peanut varieties were homogeneity.The geometric mean diameter of peanut seeds,arithmetic mean diameter and the trends of weight changes were basically same.The sizes and the uniform performances were significantly different among peanuts varieties.Many factors should be comprehensively taken into account on cleaning and grading of peanuts seed.
