Abstract: The shape, amount, and distribution of starch granules are specific to each plant. Different plants will have different shapes, quantities, and distribution of starch granules. Based on the shape, amount and distribution of starch, the types of starch producing plants can be classified. Taro (Colocasia esculenta L .) is a starch-producing plant that has the potential to be developed in the future. Colocasia esculenta L is distributed in a wide area in West Sumatra, Indonesia so that genetic variations and variations in anatomical structure are interesting to know.
