Fig.10 Correlation analysis between growth, photosynthetic and soluble sugar content and yield of sweetpotato
Note: A: The Violet variety. B: The Hami variety. VG: Vine length. LA: Leaf area. T/R: Vine ratio. Pn: Net photosynthetic rate. Gs: Stomatal conductance. Tr: Transpiration rate. Ci: Inter cellular CO2 concentration. SSC: Soluble sugar content. SC: Sucrose content. FC: Fructose content. GC: Glucose content. YLD: Yield. * indicate when the confidence level (double test) is 0.05, the correlation is significant. ** indicate when the confidence level (double test) is 0.01, the correlation is extremely significant.
