¹⁾ uRo, unripe Rubus occidentalis L; uRc, unripe Rubus chingii Hu; Ro; ripe Rubus occidentalis L..
²⁾ Data are presented as the mean±SD.
³⁾ The data were statistically evaluated using one-way analysis of variance (ANOVA) followed by Dunnett’s Multiple Comparison test to compare significant differences between the groups at ^NSp>0.05 (NS=not significant), ^*p<0.05, ^**p<0.01, and ^***p<0.001.
⁴⁾ Statistically significant from the uRO groups at ^NSp>0.05.
