In order to investigate the Possibility of utilizing corm as a seed corm In taro, the corm classified by the weight was planted on April 20, 1984. The effect of weight of corm (30, 50, 70, 90, 110, 130150r and 170g) on the growth, yield, and quality of taro was compared to those raised from cornel.The corm showed a better emergence rate than cermets regardless of its size. The larger the size ofcorm wasi the more the number of leaves developed, and the fisher the yield was. It was consideredthat the higher yield and better quality of taro was obtained by using larger corm as a mother corm( in the following year) due to the increase in the production of large taros.

In order to investigate the possibility of utilizing small cermet as a seed corm in taro, the small cermets classified by the weight were planted on April 30,2000. The effect of weight of small cermets(5,10, If,20,25, and 30g) and corms on the growth, yield, and quality of taro was compared to those raised from cermets. The larger the size of cormel was, the more number of leaves developed, and the higher the yield was. Also the growth of small cormel was normal, so we forecast that it is possible to use small cermet as seed corm in mass production of taro.

In order to investigate the possibility of utilizing cermet piece as a seed corm in taro, the cermet piece classified by the weight were planted on April 30, 2000. The effect of weight of cermets cutting by two pieces (5, 10, 15, and 20g) and four pieces (15g) on the growth, yield, and quality of taro was comparing with cormel follows as: The larger the size of cormel pieces was, the more number of leaves developed, and the higher the yield was. Also the growth of small cormel pieces was normal, so we forecast that it is possible to use small cermet pieces as seed cermet in mass production of taro.

Morphological and physiological differences of $Colocasia$ $esculenta$ were investigated in the cultivation of hydorphonic and soil culture. $C.$ $esculenta$ grown in Hoa.+IAA (indole-acetic acid) showed higher growth activity representing 9%, 32%, 38% and 60% than those of the cultivation of vermiculate, Hoagland solution, soil and water, respectively. In case of $F_v/F_m$ ratio experiments, the value $F_v/F_m$ of $C.$ $esculenta$ cultivated in the water showed 0.55 after 6 weeks. $F_v/F_m$ values of $C.$ $esculenta$ cultivated in Hoagland+IAA, vermiculate and soil were between 0.84 and 0.80 indicating $F_v/F_m$ values were about 45% higher than that of $C.$ $esculenta$ cultivated in the water. Diffusion resistance was 45~35% lower in $C.$ $esculenta$ grown in Hoa.+IAA solution than that of $C.$ $esculenta$ grown in water only after 5 and 6 weeks. Therefore, the high standing levels of the growth rate, fluorescence activity and transpiration rate were Hoa.+IAA, vermiculate, Hoagland, soil and water. The distinct morphological differences of $C.$ $esculenta$ cultivated in hydorphonic and soil culture were the appearance of the seed corm and root hair. The development of seed corm was well established in soil culture but the corm in hydorphonic was slowly hydrolyzed and then disappeared. The fibrous root systems of hydorphonic were very well distinguishable compared with that in soil culture. Outstanding results of this experiment were appeared in $C.$ $esculenta$ which was cultivated in the field provided with enough mineral nutrition, organic fertilizers and compound fertilizers. The most height taros were almost 2m and the numbers of seed corm were 30~40 after 7 months.
