<p>This study aimed to compare cormels and suckers to determine the better planting material (PM) and to evaluate the effects of morphology-altering treatments on both shoot growth and corm yield in taro plants. The PMs used included cormel (PMC), suckers with two leaves (PMS2) and suckers with four leaves (PMS4). Morphological alteration (MA) treatment included removal of all suckers (MAS), excising the mother plant (MAM), and non-treated control (NMA). Data were collected weekly for non-destructive and at 12, 20, and 28 weeks after planting (WAP) for destructive measurements. Results of this study indicated that the SPAD values were higher in taro plants grown using cormel and morphologically non-altered plants. Removal of all suckers caused the mother plant to increase the number of leaves. The dry weight of the leaf blades, petioles and fibrous roots of the mother plant and the number of suckers decreased after the corm enlargement process took place. Fresh and dry weights of the corm increased at 20 WAP and then slowed down at 28 WAP. The moisture content of corm was relatively constant at 75%. Cormel could form on the fibrous roots and on suckers, but the total wet and dry weights of the cormels were decreased if the suckers were periodically removed. The growth of suckers was very dominant compared to the NMA plant when the mother plant was excised. Meanwhile, if all the suckers were removed, the growth of the mother plant was relatively comparable to that of the NMA plants.</p>
