The morphological characterizations of ‘Bendi’ (a) and ‘Zhuye’ (b) cultivars cultured at 42 °C for 0 day, 3 days, 6 days, 9 days, and 12 days, respectively. Carbohydrate profiles of ‘Bendi’ and ‘Zhuye’ cultivars grown in long-term heat stress. Glucose content (μmol/g) (c), fructose content (mg/g) (d), starch content (mg/g) (e), and protein content (mg/g) (f) obtained from ‘Bendi’ and ‘Zhuye’ cultivars cultured at 42 °C for 0 day, 3 days, 6 days, 9 days, 12 days and 15 days, respectively. The data presented are average ± SE of three independent extractions from three replicates. The statistical analyses were conducted in the two varieties at the same time point and the significant one was labelled with asterisks (*)
