Changes in Vitamin E and β-Carotene Contents in Various Edible Cassava Leaves (Manihot esculenta Crantz) of Different Ages across Multiple Seasons

Figure 1

Total vitamin E of edible cassava leaf variety at different harvest ages. Values are given in micrograms per gram of sample dry weight (μg/gdw); MAP: months after planting. Cassava leaves varieties were harvested at 6MAP (onset of dry season, 15–20°C, 00 mm), 9MAP (main dry season, 35–40°C, 00 mm), 12MAP (onset of rainy season, 20–30°C, 300–500 mm), and 15MAP (rainy season, 15–25°C, 9500–1100 mm) months after planting. Values are expressed in microgram tocopherol equivalent per gram dry weight basis (μgα-TE/gdw). Values are mean ± standard deviation; n = 4; bars followed by different lowercase letters are significantly () different for the same harvest age. Two-way ANOVA: variety ( value = 0.040); MAP ( value = 0.000); variety × MAP ( value = 0.731).
