Starch and sucrose synthesis and metabolism in triploid-F, triploid-S and diploid plants. (A) Differentially expressed genes (DEGs) associated with sucrose and starch synthesis and metabolism on different leaf canopy positions when triploid-F and triploid-S plants were compared to diploid plants; (B) Starch, sucrose, glucose and fructose content on different leaf canopy positions when triploid-F and triploid-S plants were compared to diploid plants; (C) SUS, SPS, and AMS enzyme activity on different leaf canopy positions when triploid-F and triploid-S plants were compared to diploid plants. Different lowercase letters represent significant differences at p < 0.05.
