摘要
采用不同质量浓度石墨烯的MS培养基,测定藜麦幼苗根系投影面积,利用回归分析法对石墨烯浓度与藜麦幼苗根系投影面积进行二次曲线回归,得到回归模型并进行检验,研究石墨烯浓度与藜麦幼苗根系投影面积变化的规律。结果表明,模型的P值小于0.05,说明该模型可以良好地反映两者之间的关系;模型的R^(2)值为0.984,回归系数达显著水平。因此该模型适合描述石墨烯浓度和藜麦幼苗根系投影面积的关系,可以对试验结果进行科学预测。
This study prepared MS medium containing different concentrations of graphene and studied the effect of projected area of quinoa seedlings.Through regression analysis which quadratic curve was used to graphene concentration and root projected area of quinoa seedlings,the relationship between graphene concentration and root projection area of quinoa seedlings was studied.The results showed that the P value of the model was less than 0.05,indicating that the model could well reflect the relationship between the two;the R^(2) value of the model was 0.984,and the regression coefficient reached a significant level.Therefore,the model was suitable for describing the relationship between graphene concentration and root projected area of quinoa seedlings,and could predict the experimental results scientifically.
