Influence of Soil Moisture on Germination and Growth of Corn (Zea Mays L. Var. Tainung No. 351)

Te-Chen Kao

Summary

　　A new high yield corn variety, i.e., Tainung No. 351, is released recently which provided as a substitute for paddy rice. This preliminary study is aimed to evaluate the flooding resistant ability of Tainung No. 351. As compared to check varieties, Tainan No. 5, Tainan Yu-6 and Tainan No. 11, Tainung No. 351 could germinate well in a wide soil moisture range between 45.2% to 86.2% of maximum holding capacity (MHC) and checks only showed good germination at 72.7% MHC. Tainung No. 351 could also get 45.0% of higher germination rate than others after a 2-day flooding treatment. It was found that CaO₂ seed-coating material could not improve the low germination tendency caused by flooding.

　　However, CaO₂ coated seeds reduced microorganism infection by 41.3%. While different ages of seedlings were under a 5-day flooding treatment, 10 days old seedlings were more sensitive to flooding than other stages. Flooding treatment caused lower leaves to wilt and show yellow color. In conclusion Tainung No. 351 is more suitable for a substitute in paddy field than check varieties.
