摘要
为探究比重、孔隙度与饱满度之间的关系,测定了131份小麦籽粒的容重和比重,并对容重与比重和孔隙度之间的关系进行回归分析,以实现用比重、孔隙度定量描述籽粒饱满度。结果表明,籽粒容重和比重呈线性正相关,与孔隙度呈线性负相关;回归方程式分别为y_(容重)=829.84 x_(比重)-286.25和y_(容重)=-16.212 x_(孔隙度)+1414.2,对应的R_(2)值分别为0.5995和0.7202。“饱满”、“较饱满”、“一般”、“较瘪”、“瘪”的籽粒对应的比重范围分别为≥1.297、1.273~1.296、1.249~1.272、1.225~1.248、1.201~1.224 g·cm^(-3),对应的孔隙度范围分别为≤38.50%、38.51%~39.74%、39.75%~40.97%、40.98%~42.20%、42.21%~43.44%。
To explore the relationship between specific gravity or porosity and kernel plumpness,test weight and specific gravity of 131 groups of wheat kernels were determined in this research,and the regression equation for test weight and specific gravity or porosity was established.Combining with the relationship between test weight and kernel plumpness,wheat kernel plumpness was quantitatively described by specific gravity and porosity.The results showed that test weight was linearly and positively correlated with specific gravity but linearly and negatively correlated with porosity.The regression equations were y_(TW)=829.84 x_(SG)-286.25(TW means test weight and SG means specific gravity)and y_(TW)=-16.212 x_(P)+1414.2(P means porosity).The specific gravity ranges corresponding to the plumpness grades of‘plump’,‘less plump’,‘medium’,‘less shrunken’,‘shrunken’were≥1.297,1.273-1.296,1.249-1.272,1.225-1.248,1.201-1.224 g·cm^(-3) respectively,and the corresponding porosity ranges of these plumpness grades were≤38.50%,38.51%-39.74%,39.75%-40.97%,40.98%-42.20%and 42.21%-43.44%,respectively.
